DryLin® N Low Profile Linear Guide Systems

The DryLin® N series offers extremely low profiles in several widths, and is therefore ideal in tight spaceconstraints. Like all DryLin® products the carriages are designed to glide smoothly on anodized alu-minum rails without the need for messy lubricants. They are also available in preloaded versions forreduced running clearance. DryLin® N is a particularly low-cost alternative to miniature ball bearingsystems, and is more precise and economical when compared to many custom-machined or simpleplastic parts.

� Small mounting height and width

� Maintenance-free and self-lubricating

� High resistance to dirt

� Corrosion-resistant

� Low wear and low coefficient of friction

� Lightweight due to aluminum polymer combination

� Very high speed and acceleration possible

� Replaceable polymer sliding elements made of iglide® J

� Base structure of the carriage made of plastic (size 17)or zinc, chromated (size 27, 40 and 80)

� Anodized aluminum rails

� Available from stock

NW 80

The largest of the DryLin® N series permits low installation heightswhile offering high load-bearing capacity. The lubrication free designis capable of running at high linear speeds.

NW 40

Compared with smaller series, NW 40 is able to withstand significantlyhigher loads. Like all other DryLin® N series, the lubrication free designis capable of running at high linear speeds.

NW 27

The NW 27 series is available in 2 different versions: As a slide with aplain bore, and as a slide with a threaded bore. The lubrication freedesign is capable of running at high linear speeds.

NW 27 PreloadLike NW 17 Preload, this larger NW 27 Preload model of DryLin® Npossesses the special feature of automatic pre-tension.

OvermoldedThis version is practically identical to the standard slide NW-01/02-27. Overmolded with iglide® J, however, it is easier to assemble andstore large quantities.

Quick assembly

Easier handling

NW 17

The smallest size of the DryLin® N range is designed to have minimumdimensions coupled with a high load capacity. In addition, this rangeis free from lubrication and can run at high speeds.

NW 17 PreloadThe NW 17 Preload model of the DryLin® N series provides for anautomatic pretension to the rail.

http://www.igus.com/RoHS.asp

When using systems with 2 parallel rails, one side must be designated as the “fixed” rail, and the opposite side the “floating” rail.

Why use floating bearings?• promotes smooth gliding performance and maximizes bearing life• prevents binding caused by parallelism and angle errors• decreases necessary drive force and wear by minimizing friction-forces• Enhances the precision of the system over the bearings’ lifetime.• Reduce assembly time and cost

Fixed BearingsThe “fixed” bearing rail should be positioned closest tothe drive force. This rail will determine the precision ofthe system; no system should contain more than two“fixed” bearings.

Floating/Self-Aligning BearingsThe “floating” rail should be the rail located furthest fromthe drive force. It is to act only as a guide, and willcompensate for any misalignments or angle errors in thesystem ensuring proper functionality.

Mounting SurfacesThe mounting surfaces for rails and bearings should havea very flat surface (e.g milled surface) in order to enhanceperformance. Variations in these surfaces may becompensated for by using floating bearings.

Fixed and Floating Bearing Mounting Instructions

Eccentric Forces

2:1 Rule =

permissible distances

of the applied forces


The 2 :1 RuleWhen using linear plain bearings it is important to ensure that the acting forcesfollow the 2:1 Rule (see drawing). If either the load or the drive force (F) isgreater than twice the bearing length (1X), then a binding or interrupted motionmay occur.If the location of the drive force or load cannot be changed, simply increasethe distance between the bearings, or create a counterbalance to move thecenter-of-gravity back within the 2 to 1 ratio.
