This cold drawn profile is produced by Rathbone Precision Metals, Inc. for the linear motion industry. This carriage insert profiles are produced in bearing quality 52100 steel and requires exacting tolerances and surface finish to provide low-weight solutions for critical high performance applications.
Rathbone produces this carriage insert to a profile of line tolerance of 0.002” with a critical web dimension that is held to within .001” over the length of the 8 foot bars provided by Rathbone to the customer. Straightness of the 8 foot bars we supply is held to 0.015” per foot maximum.
Being that this for a wear application, surface hardness and surface finish of the carriage insert are both critical. Rathbone produces this profile with a surface decarburization limit of partial and full being held to with 0.002”. This supports the customer achieving the required surface hardness when heat treating the insert. The surface finish as supplied Rathbone is 63 µRa maximum.
