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 result is a rigid, smooth operating motion system. Depending on the load requirements, the BGS04 linear rail is available with either the Size 11 (28mm) double stack or Size 17 (42mm) single stack hybrid linear actuator. The BGS04 is carefully designed to maintain accuracy while moving heavy loads. Maximum roll, pitch, and yaw moments are 7.75Nm, 6.60Nm, and 7.70Nm, respectively. Maximum horizontal load is 100N. Lead screw resolution available for the BGS04 ranges from 0.635mm to 25.40mm per revolution. When combined with a 200 step/rev stepper motor, linear positioning resolution is greatly enhanced to a range of 0.003 to 0.127mm per input pulse. Stroke length of the BGS04 is 25mm to 460mm.
