About Moment Loads

Hand Brake Shown Installed

Standard Carriage

Load Fastening from Top

Operating with less friction than sleeve and roller bearing carriages, ball bearing carriages provide accurate movement and positioning in high-speed, high-load applications. However, they don’t hold up to dusty and wet environments as well as sleeve bearing carriages. Mount in any orientation without affecting load capacity. End seals keep lubricant in and dirt out. Add optional guide rail bellows to protect the rails from contaminants as carriages move across them.

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

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. Carriage and guide rail systems for 5 mm-12 mm wide rails include mounting hole plugs with the guide rails.

Note: Each carriage can only be used with its corresponding guide rail.

Clean Room Ball Bearing Carriages and Guide Rails

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.

Miniature Ball Bearing Carriages and Guide Rails

These tiny carriages and guide rails are sized for electronic and other precision applications. They come furnished as a complete unit (a carriage on a guide rail). Mount in any orientation without affecting load capacity.

Note: Ball bearings do not have a cage, so they’ll fall out if the carriage is removed from the guide rail.

Anti-Reflective Miniature Ball Bearing Carriages and Guide Rails

Load Fastening from Top

Small enough to fit in a camera zoom lens and other precision motion applications, these carriages and guide rails have a black chrome-plated finish that diffuses light to prevent reflecting light from causing equipment to malfunction. They are also useful in positioning systems that use photosensors, which are sensitive to light. The finish gives you two times more rust resistance than 440 stainless steel alone. The carriage comes already installed on the guide rail. However, the ball bearings don’t have a cage, so they’ll fall out if you remove the carriage from the guide rail. Mount them in any orientation without affecting load capacity.
