Haydon Kerks BGS04 linear rail system

Haydon Kerks BGS04 Linear Rail System is designed specifically for high moment loads. The roll, pitch and yaw moment load capability of the BGS04 allows the system to maintain tight accuracy and repeatability, even in applications requiring significant cantilevered loading.

The product is designed to maintain accuracy while moving heavy loads. Maximum roll, pitch and yaw moments are 7.75, 6.60 and 7.70 Nm respectively. Maximum horizontal load is 100 N. Stroke lengths are 25 to 460 mm, with screw pitches ranges from 0.635 to 25.40 mm/rev.

At the heart of the product is a Haydon linear actuator driving a Kerk 303 stainless steel precision lead screw. The screw is coated with Black Ice TFE coating, providing a permanent wear-resistant dry lubrication. The lead screw drives an anti-backlash nut embedded in a machined aluminium carriage mounted to a stainless steel ball rail. The result is a rigid, smooth-operating motion system.

Depending on the load requirements, the linear rail is available with either the size 11 (28 mm) double stack or size 17 (42 mm) single stack hybrid linear actuator.

When combined with a 200 step/rev stepper motor, linear positioning resolution is greatly enhanced to a range of 0.003 to 0.127 mm per input pulse. The product can be further customised to better suit the user’s design. This includes custom wire harnesses, load carriages and mounting configurations.
