Kerk Motion Products Offers Extended-Wear LR Series Linear Rail System for a Variety of Applications



Low cost, precision system is ideal for many industries

Kerk Motion Products, one of the world's premier manufacturers of non-ball lead screws, offers the LR Series linear rail system. The LR Series is designed for light load applications where minimal frictional drag, long-wear life and low cost are the primary concerns. Ideal applications include: office automation, bench top automation, medical analysis equipment, data storage equipment, general purpose positioning in pick and place equipment, general and electronic assembly and dispensing systems.

The LR Series System consists of a centerless ground and burnished stainless-steel shaft mated with a graphite- and PTFE-filled thermoplastic bushing, formulated so that thermal fluctuations have minimal effect on system performance. Kerk's LR Series is available with or without TFE coating, and requires no lubrication or maintenance. This proprietary coating increases lubricity, extends life on support shafts and is available with both the stainless and alloy steel models.

Kerk's LR Series features a standard shaft straightness of .002"(0.05mm) per foot. The typical radial clearance between shaft and bushing is .0005" (0.013mm) on non-coated assemblies and .001"(0.025mm) on TFE coated assemblies. Bushings are manufactured with standard retaining ring grooves.

Standard configurations for the LR Series include ¼", 3/8", ½" and ¾" nominal diameters. Kerk Motion Products can provide custom diameters and bushings, including multifunction bushings and combined lead screw/linear rail assemblies.
