Detailed Description

Timken 203FF is a deep groove bearing engineered for steering and pump-related rotating loads. Its dimensional profile makes it a direct match for many power steering pump shaft repairs, including applications found on Chevrolet Corvette, Chevrolet S10, Cadillac Eldorado, Buick Riviera, and other listed vehicles. The bearing design emphasizes consistent rotation, controlled vibration, and dependable fitment where the shaft and housing dimensions must remain precise.

This part cross-references SKF 6203-2RS15 for the same application. Timken 203FF also follows ISO dimensional standards, which helps simplify replacement when servicing OE-style assemblies or rebuilding a pump that uses a 6203-size bearing format.

Common Repair Uses

• Replacing a worn power steering pump shaft bearing

Installation Notes and Tips

Verify the bearing dimensions before installation: 17.00 mm inside diameter, 40.00 mm outside diameter, and 12.00 mm width. Inspect the shaft, housing, and lubrication condition during service, since contamination or scoring can shorten bearing life. For best results, install the bearing into a clean, properly prepared pump assembly and confirm free rotation after assembly.

Quality Assurance

Timken deep groove ball bearings are manufactured to rigorous worldwide quality standards and built to ISO dimensional requirements for interchangeability. The 203FF uses tight tolerances and a refined surface finish to support stable operation in steering pump service.
