Haydon Kerk Motion Solutions BGS08 designed for high loading capability.
Haydon Kerk Motion Solutions introduced its BGS08, the latest addition to the company’s BGS linear rail product line, designed for high loading capability. Maximum roll, pitch, and yaw moments are 22.5 lb-ft (30.5 Nm), 19.4 lb-ft (26.3 Nm), and 22.3 lb-ft (30.2 Nm) respectively. Maximum horizontal load is 225 lbf (1,000N).
Lead screw resolution available for the BGS08 ranges from 0.098-in (2.50mm) to 1.00-in (25.40mm) per revolution. When combined with a 200 step/rev stepper motor, linear positioning resolution ranges from 0.00049-in (0.0125mm) to 0.005-in (0.127mm) per input pulse. Stroke length is 1-in (25mm) to 30-in (760mm).
At the heart of the BGS08 is a Haydon size 23 (56.4mm) 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. Depending on the load requirements, the BGS08 linear rail is available with the size 23 single stack or double stack stepper motor.
