Custom lead screws for transportation applications
Kerk Motion Products is offering its custom lead screw and nut for automatic door actuation.
The LR Series system consists of a centreless 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 0.05mm per foot.
The typical radial clearance between shaft and bushing is 0.013mm on noncoated assemblies and 0.025mm on TFE coated assemblies.
Bushings are manufactured with standard retaining ring grooves.
Standard configurations for the LR Series include 0.25, 0.375, 0.5 and 0.75in nominal diameters.
Kerk Motion Products can provide custom diameters and bushings, including multifunction bushings and combined lead screw/linear rail assemblies.
