The unique lock mechanism provides a strong holding force that is equivalent to doubled thrust force (with working pressure of 0.4 MPa)

Powerful rod holding force

Tie rod cylinder with brake

The same mechanism as the popular JSC3 Series has been adopted for the brake section to ensure a reliable durability. This achieves reliable endurance.

Compact, reliable, and proven brake

Small-size switchA T-type switch, smaller than the conventional type, has been incorporated. This eliminates the protruding switch and saves space when installing.

Ports and needles on the same surfaceAir provision and evacuation ports are located on the same surface with the cushion needle. Cylinder attachment and adjustment have been made easier.

Magnet provided as standard <LN and LH>

Switches can be additionally mounted on all products (LN and LH).

Compatibility of mounting dimensions sizes <except for LH>

Compatible mounting dimensions with the conventional type (JSC3) for ease of maintenance * Piping port positions have been changed.

Unified to aluminum colorSilver (aluminum color without paint) has been adopted for the product surface color to match various devices.

Usage example

Applications

When different-sized products flow to the conveyor, etc., and many cylinders are set, the stroke must be changed. Using the middle bore size brake cylinder, a cylinder compatible with different strokes is created electrically.

When a hopper has to be closed at a specific weight, such as in a milling process, the hopper is closed just before it is fully closed to accurately measure the powder, and then it is fully closed.

When locking a workpiece on a jig, using a brake cylinder keeps the workpiece locked after the air pressure or power supply is cut off.

If there is a vertical load that could drop of its own weight when the pressure source is turned off, brakes are applied to the lock position.

When welding steel plates, etc., linearly at several points, this cylinder can be used to move and position the slide table or welding gun.

When locking a workpiece on a jig or installation unit, it can be locked without the air pressure and power supplies. The workpiece can be transferred while locked to the jig.

Electric signal immediately stops the cylinder when an opera-tor enters a dangerous area.

Brakes can be applied and held instantly when the air pressure source or power is turned OFF during power failure or accident, preventing damage to equipment and ensuring safety.

High stoppage accuracy is achieved for many target positions.

■ Structure so that nothing directly touches the driven object or movable sections of the cylinder with brakes.Provide a protective cover so that no human-body directly touches the unit. If parts contact is possible, provide safely measures by placing a sensor to stop the cylinder or sound a warning to report danger.

■ Use a balance circuit considering piston rod protrusion.When activating brakes at any position in the stroke, if pneumatic pressure is applied to only one side of the cylinder, the piston protrudes at high speed when brakes are released. This involves risk to personnel such as pinching a limb and damage to equipment. Use a balance circuit, such as the basic circuit, to prevent protrusion.When using the low hydraulic pressure type brake cylinder, always apply the brakes with the pneumatic pressure.

■ Holding force (maximum static load) refers to performance to hold a static load without vibration or impact when brakes are activated in a no-load state.Take care when constantly using near the upper limit of the holding force.

■ Do not apply loads with impact, strong vibration, or torque while brakes are activated.If a load with impact, strong vibration, or torque is applied externally, holding force drops.

■ Put the stoppage accuracy and overrun length in consideration when braking.A mechanical lock is applied, so the cylinder does not stop instantly when the stop signal is issued, but stops with a time-wise delay. The stroke caused by this delay is the overrun length. The width of the minimum and maximum overrun length is the stoppage accuracy.● To achieve the required stop position, move the limit

switch forward by the overrun distance.● The limit switch must have a detection length (dog length)

● When using the CKD cylinder switch, the working range is 7 to 16 mm, depending on the switch. If overrun distance exceeds this, provide self-holding of the contact at the switch load.

■ To improve stopping accuracy, minimize the time from stop signal output to brake stoppage.Use a high-response DC control electricity circuit or solenoid valve, and set the solenoid valve as close to the cylinder as possible.

■

disturbance during cylinder reciprocation, stop position dispersion increases. Take measures to keep piston speed constant just before the stop position. Speed changes are large during the acceleration range, compared to during the cushion stroke and when starting operation, so dispersion in the stop position increases.The stoppage accuracy is ±1.0 mm (reference) with piston speed of 300 mm/s without load. This value varies depending on the device used. For details, see the page of “Stoppage accuracy and overrun.”

■Basic circuitWhen using this cylinder for position locking or emergency stop, use the circuits below. The 2-position valve cannot be used since cylinder thrust is also applied to brakes when slopped.Use the circuit shown below to keep balance of the thrust and the load. Brakes may not be released when load is applied to brakes.● Parallel loadIf piping is as shown in Fig. 1, equalizing pressure is applied to both ends of the piston when stopped to prevent the rod from protruding when brakes are released. Install a regulator with a check valve on the head end to keep balance of the thrust.

■Stoppage accuracy● Stop pitch and load ratioStopping accuracy differs with the stop pitch and the load factor.The table below lists the recommend load factors.

■ Do not make major changes in load weight when stopped with brakes, or the stopping position may change. Doing so may change the stopping position.

● Vertical downward loadIf the load faces downward as shown in Fig. 2, the rod malfunctions in the load direction when brakes are released. Place a regulator with a check valve on the head to reduce thrust in the load direction and balance the load.

● Vertical upward loadIf the load faces upward as shown in Fig. 3, the rod malfunctions in the load direction when brakes are released. Place a regulator with a check valve on the rod to reduce thrust in the load direction and balance the load.

■ Release brakes before coupling the load to the end of the rod.If coupled while brakes are applied, torque or load exceeding holding force may be applied to the piston rod and damage the brake mechanism.

■ If brakes are released when air is pressurized on only one side of the cylinder, the piston may protrude at high speed, causing a hazard. When releasing the brake for maintenance etc, follow the following precautions.● Check that no one is in the movable range of the load and that

no problem arises if the load moves when brakes are released.● Take the following measures to prevent the load from

dropping when brakes are released:- Place the load on the lowering end- Put pressure on both sides- Place a supporting postPerform the drop prevention actions above.

●cylinder when releasing brakes.

■ How to release the brake manually

Note: How to release the brake● To release the brake, screw in a release bolt (attached to

the product) a few rounds into the screw at the top of the brake (next to the brake release port).(Always remove the releasing bolt during normal use.)

● Always use the release bolt attached to the product when you manually release the brake. Using any other bolt may damage the brake by over-tightening. Observe the degree of tightening indicated in the table below when using a general bolt.

■ Brakes are released manually or by pressurizing the brake release port. With a load, the load may drop if brakes are left released with either of these operations. Before attaching the load, check that brakes can be applied from the initial state when using manual release or from when air is not applied to the brake release port.

■ Do not apply torque to the rod in locked state because holding force drops and create a hazard. Use a mechanism that does not rotate the rod.

■ Do not apply brake holding force to the cylinder exceeding that indicated in the catalog.

JSC4 SeriesIndividual precautions

■ Adjust the cylinder air balance.With brakes released, place a load on the cylinder and balance the load by adjusting air pressure applied to the cylinder rod and head. Faults such as cylinder protrusion during brake release or improper brake release are prevented by accurately balancing the load.

■ Adjust the installation positions of detectors such as the cylinder switch.When using braking, consider overrun distance for the required stopping position, and adjust the position of detectors such as the cylinder switch.

■ leads to changes in the piston speed, which in turn increases dispersion in the stop position. Adjust the installation so that there is no load change just before the cylinder stops in the back-and-forth movement.

■ Speed changes are large during the acceleration range compared to during the cushion stroke and when starting operation, so dispersion in the stop

therefore not be attained in step operation with a short stroke from the starting position to the next position.

■ Load on piston rodCompared to using a general-purpose air cylinder, check that load applied totally to the piston rod is applied in the axial direction. Limit load movement using guides so that play or torsion does not occur.

■ Maintenance of rod sliding sectionHandle carefully to prevent scratching or denting the piston rod sliding section These can result in damage to packing, leaks, or brake faults.

■ If there is any play, such as looseness, in the brake signal dog, stopping accuracy is affected. Securely

■ If piston speed is fast, the detection dog must be long enough to match relay response time. If the dog is short, the stop signal is not output and operation does not stop.

Caution

■ The brake section can be removed from the cylinder body. Do not disassemble or inspect brakes or hazards may result when brakes are used again.

■ Avoid applying extra grease and do not wipe grease off. Do not wipe off greases on the brake shaft, neither.

■ Adequate amount of grease is applied to spare brakes, so you need not to put grease on the rod when replacing a brake.

■ To prevent faults, use a dust cover during operation except when manually releasing brakes.

■ If you remove the manual releasing bolt when the piston rod is removed, you cannot screw in the manual release bolt. If you have removed the piston rod, supply air from the brake release port when you screw in the manual release bolt.
