About Moment Loads

Standard Carriage

Flanged Carriage

Load Fastening from Top

Load Fastening from Bottom

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.

Flanged carriages have threaded mounting holes on the flanges rather than the carriage body, so you can fasten loads from both the top and bottom. When fastening from the bottom, use the mounting hole as a through-hole.

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.

Anti-Reflective Ultra-Corrosion-Resistant Ball Bearing Carriages and Guide Rails

Carriage

Load Fastening from Top

Guide Rail

A black chrome plating diffuses light, preventing reflecting light from causing equipment to malfunction. They're great for precision positioning systems that use photosensors or cameras, which are sensitive to light. The finish also resists rust two times better than 440 stainless steel alone. They have ball bearings, so they operate with less friction than sleeve and roller bearing carriages for accurate movement in high-speed, high-load applications. However, they don’t hold up to dusty and wet environments as well as sleeve bearings. These carriages have a standard profile that’s narrower than flanged carriages, making them better for confined spaces.

Note: Each carriage can only be used with its corresponding guide rail. Load capacity is diminished when carriages are mounted upside down or on a vertical surface.

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. 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.

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.

Mount 1 mm wd. rails with mounting brackets (sold separately; order one for each end of the guide rail).

High-Cycle Low-Profile Ball Bearing Carriages and Guide Rails

Carriage

Load Fastening from Top

Guide Rail

Run many cycles in tight spaces before replacing or re-greasing carriages. These low-profile carriages have a plastic cage surrounding the ball bearings to keep them from colliding with each other. This reduces the noise, heat, friction, and dust they produce, so carriages can travel back and forth along the rail many times. The cage also traps grease around the balls and makes sure they roll in the same direction. Ball bearings provide accurate movement and positioning at high speeds under heavy loads. Made of stainless steel, all of these carriages and guide rails are corrosion resistant. Each carriage has end seals to keep lubricant in and dirt out.

Mounting hole plugs protect mounting fasteners from corrosion.

10 mm carriages and guide rails include mounting hole plugs.

Miniature Pass-Through Drawer Slides

The size of a finger, these tiny slides open in both directions. All have ball bearings for smooth operation.

Stainless steel slides resist corrosion, so they're commonly used in medical, laboratory, and other fixtures that are often cleaned.
