This stainless steel MGN12H carriage from KB3D carries a Z1 Preload to match our standard house brand rails!  To be used as a spare or second carriage. Sold Each.

NOTE: These carriages are offered for those looking to utilize KB3D branded linear rails in an IDEX or similar configuration. If you are aiming to replace the carriage on an existing KB3D rail please leave the tolerance markings in the notes during checkout. This can be found on the underside of the carriage with the rail removed. Avoid using our carriages with other rail manufacturers -- not all rails are created equal!
