Timken 104CC Power Steering Pump Shaft Bearing

The Timken 104CC is a deep groove ball bearing used in steering-related applications where smooth rotation and stable support matter. It is built for low noise and vibration, with tight tolerances and a refined surface finish that support higher operating speeds when properly lubricated.

Compatible with 1985-1986 BMW 735i and 1979-1981 BMW 528i applications, this bearing follows ISO dimensional standards for straightforward replacement. The Timken 104CC also cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Key Features

• Deep groove ball bearing for steering pump shaft support
• Noise and vibration control for smoother operation
• Tight tolerances and finished race surfaces for consistent performance
• ISO-standard dimensions for interchangeability
• Timken quality control for global aftermarket use

Detailed Description

Timken 104CC is a power steering pump shaft bearing engineered as a direct-fit replacement in select BMW applications. It is designed to maintain shaft alignment and reduce rotational friction in the steering pump assembly, helping preserve smooth steering system operation in 1985-1986 BMW 735i and 1979-1981 BMW 528i models.
