Linear rail system takes a maximum horizontal load of 1,000N

November 06, 2012 // By Julien Happich
Haydon Kerk Motion Solutions' BGS08 ball guide screw linear rail is designed to position heavy loads and maintain tight accuracy and repeatability even in applications requiring significant cantilevered loading.

The BGS08 was designed specifically for high loading capability with maximum roll, pitch, and yaw moments of 30.5Nm, 26.3Nm, and 30.2Nm respectively. Maximum horizontal load is 1,000N. Lead screw resolution available for the BGS08 ranges from 2.50 to 25.40mm per revolution. When combined with a 200 step/rev stepper motor, linear positioning resolution is greatly enhanced to a range of 0.0125mm to 0.127mm per input pulse. Stroke length of the BGS08 is 25 to 760mm. At the heart of the BGS08 is a Haydon size 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. The result is a rigid, smooth operating motion system. Depending on the load requirements, the BGS08 linear rail is available with the size 23 single stack or double stack stepper motor.
