BEARINGS Bearing Quality All bearings meet or exceed AFBMA standards and ISO standards. The latest testing equipment is in use at each of our sources. FIT Bearings continually inspects and surveys each plant's facilities, production equipment, and instrumentation to assure that they have the capabilities to meet the highest quality standards. Their commitment to quality is also reviewed. Lubrication can be specified to meet your requirements, whether using oil, U.S. grease, or any other grease. Steel used is bearing quality vacuum degassed 52100 or 440c stainless. Balls are grade 5 or better. Bearing parts are cleaned with modern equipment, then assembled, lubricated and packaged in a controlled environment.
