KSS

STOBER Drives Inc. is proud to offer our quality-proven, high-efficiency “K” Series Helical/Bevel speed reducer in a stainless steel housing. Theadaptability of the well known double wobble-free bushing, with expanded bore sizes, makes this unit necessary for the toughest washdownapplications. The footprint is smaller (30% less) than the standard unit but the “KSS” uses the same high quality helical gearing which is casehardened to 58-62 Rockwell C and precision finished for low noise and long service life. The high efficiency (97%) assures realibility plus costsavings in energy and maintenance.

Performance Specifications:• Torques up to 3,100 in.lbs. (350Nm) • Maintenance free – Lubricated for Life

• Output Bore Diameters up to 11/2 inch • Application Specific Mounting Position

• Ratios up to 178:1 • Bushing allows mounting from either side

• Totally Enclosed – no breather to allow contaminates in or oil out • Shipped filled with Mobile CIBUS SHC 220-H1 Food Grade Oil

• 304 Stainless Steel Housing • ALL Stainless Steel Hardware

• 3 Year Warranty Standard • Laser Etched Nameplate Data

Uses the patented (U.S. Patent Number 5,496,127) Stainless Steel Double Side Bushing mounted into stainless steel output quill – easily installsonto standard stainless steel shafting

E12 E34 EL5 EL6

E12 Side 1 or side 2 can be the down side with this mounting position.

E34 Side 3 or side 4 can be the down side with this mounting position.

EL5 Side 5 is the side opposite the motor. Side 5 is the down side for EL5.

EL6 Side 6 is the input or motor side. Side 6 is the down side for EL6.

DO NOT MOUNT any STOBER reducer in a position other than specified on the order.All STOBER units are filled with the correct amount of lubrication before shipping. In order to provide the proper lubrication quantity the mountingposition must be specified at the time the unit is ordered.

For oil quantity in each size and mounting position, see our web site: http://www.stober.com/pages/lubrication-quantity.

Motor Mounting SpecificationsSTOBER servo gearheads will fit the motor of your choice by assembling a motor mounting plate between the motor and the gearhead. Whenordering a gearhead, specify the motor manufacturer and part number, provide the motor drawing with dimensions, or specify themotor mounting dimensions. The motor plate thickness (L9) is determined by the motor shaft length. For a precise dimension on a specificmotor, contact STOBER Technical Support.The following dimensions are required to provide the correct motor mounting plate:1. D6 Shaft Diameter (If an adapter bushing is required it will be supplied with the motor plate.)2. D7 Pilot Diameter3. D8 Bolt Circle Diameter4. D9 Bolt Diameter5. L11 Motor Shaft Length6. L12 Pilot Length7. L14 Square Flange (Optional – Motor plate will typically be made to match.)

MaintenanceWith STOBER reducers very little maintenance is required under normal operating conditions. Units supplied without breathers are lubricated for lifeand maintenance free.
