Linear rail system

The BGS04 linear rail system from Haydon Kerk Motion Solutions handles high moment loads.

The BGS04 linear rail system from Haydon Kerk Motion Solutions handles high moment loads. Its roll, pitch, and yaw-moment load capability lets it maintain tight accuracy and repeatability, even for applications requiring cantilevered loading.
• A linear actuator drives a 303 stainless-steel precision leadscrew. The leadscrew, coated with Black Ice TFE for permanent wear-resistant dry lubrication, drives an antibacklash nut embedded in a machined aluminum carriage mounted to a stainless-steel ball rail.
• Depending on 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.
• Designed to maintain accuracy while moving heavy loads, the unit’s maximum roll, pitch, and yaw moments are 5.72 lb-ft (7.75 Nm), 4.88 lb-ft (6.60 Nm), and 5.68 lb-ft (7.70 Nm), respectively. Maximum horizontal load is 22 lb (100 N). Leadscrew resolution ranges from 0.025 to 1.00 in. (0.635 to 25.40 mm) per revolution.
• When combined with a 200 step/rev stepper motor, linear positioning resolution is enhanced to 0.000125 to 0.005 in. (0.003 to 0.127 mm) per input pulse. Stroke length is 1 to 18 in. (25 to 460 mm).
