A company manufactures a linear rail platform 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. At the heart of the BGS04 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 aluminum carriage mounted to a stainless steel ball rail. The BGS04 linear rail is available with either the Size 11 (28 mm) double stack or Size 17 (42 mm) single stack hybrid linear actuator.
