FAQ

Question?
What carriage or runner block is compatible with this R044580431 guide rail?

This rail is a size 9 MNS rail. It is compatible with Bosch Rexroth MNN and MNS series runner blocks of size 9, such as the R04428xxxx series. Always check the datasheet to ensure the accuracy class and preload match your application requirements.

According to standard Bosch Rexroth specifications for MNS size 9 rails, the standard hole pitch (T) is 20 mm. For a 76mm rail, the end dimensions (T1) would typically be 8mm, resulting in a hole pattern of 8-20-20-20-8 mm from the end. It is crucial to verify this against the official manufacturer drawing for precision mounting.

While it is physically possible to cut a hardened steel rail, it is not recommended. Cutting can compromise the rail's straightness, introduce burrs that interfere with the carriage movement, and damage the hardened raceways. It is always best to order a rail manufactured to the exact required length from the factory.
