About Moment Loads

Standard Carriage

Load Fastening from Top

Guide Rail

Suitable for clean room use, these carriages and guide rails are made entirely of stainless steel. Ball bearings provide accurate movement and positioning at high speeds under heavy loads. Mount in any orientation without affecting load capacity. End seals keep lubricant in and dirt out.

Standard carriages are narrower than flanged carriages, making them better for confined spaces.

Add mounting hole plugs to protect mounting fasteners from corrosion.

For made-to-order guide rails, please specify the length of the rail (in 1 mm increments). The mounting holes will be centered along the rail.

Made of stainless steel, these carriages and guide rails are more corrosion resistant than steel carriages and guide rails. An internal reservoir continuously supplies grease for maintenance-free operation, making them great for hard-to-reach places.

Hand Brake

Designed for use on horizontal surfaces, the contact angle of the ball bearings on the rail allows these carriages to last longer than other carriages. The ball bearings operate with less friction than sleeve and roller bearing carriages to provide accurate movement and positioning at high speeds under heavy loads. However, they’re worse than sleeve bearings in dusty and wet environments. A plastic cage separates the ball bearings to minimize noise, reduce heat buildup, and eliminate ball collisions. End seals keep lubricant in and dirt out.

Flanged carriages have mounting holes on the flanges rather than the carriage body, so you can fasten loads from both the top and bottom.

For made-to-order guide rails, please specify the length of the rail (in 1 mm increments). The mounting holes will be centered along the rail.

Add a hand brake to lock carriages in position. To install, fasten the brake to the same mounting surface as your carriage.

Mounting hole plugs protect mounting fasteners from corrosion.
