Curved Linear Rail System (CR40 Series)
For applications where you don’t want to move in a straight line, we offer our curved linear rail guide products.
The rails are machined from carbon steel blanks, then surface heat treated to provide a hard wear resistant surface. Additional post treatment results in a satin black color appearance. Among the standard catalog products available now are straight, 90-degree turn, and 180 degree turn rail sections, as well as curved linear rail sections for building systems. CR40 Series Carriages are designed with three cam roller wheels for smooth movement.
For many applications our standard catalog offering of linear curved rail products, listed below will allow you to construct a complete system.
Below is a list of components required to make the example closed loop curved rail system in the sketch below. These systems often include a variety of curved linear rail sections.
Rail sections for any of the straight or turn pieces can be “butt” join together to allow smooth transition of the carriage as it moves along the curved linear rail track.
To assist in making the best possible alignment on your end during installation, it is advisable to purchase an alignment tool.
It is important to also note that the base upon which you install the rail sections should be machined flat and of good structural integrity to support the curved linear rail system.

Carriage and Rail Assembly Photos
Carriage assembly is made of square shaped plate (12.7 mm thick) with three cam roller bearings attached. It is made of unhardened steel to allow for additional machining if customer wishes to add their own mounting holes.
Total height from bottom of rail to top of carriage is 28.7 mm.
Clearance between the bottom of each cam roller to the bottom of the rail is approximately 1.3 mm.

Lubricant Requirements
Applying a small amount of an NLGI #2 lithium-based grease with no solid additives such as MoS2 (molybdenum disulfide) along the surface where the cam roller wheel contacts the curved linear rail is recommended for quiet operation and long life.
