Product Overview

The RA-32520020/18 RICH is a highly reliable **Double Row Angular-Contact Ball Bearing** specifically engineered for operation in the demanding environment of an automotive **Air Conditioner (A/C) compressor clutch**. Manufactured by RICH, this unit is built with high precision to effectively manage the substantial combined radial and axial loads generated by the clutch pulley.

This model combines two essential performance characteristics: **C3 internal clearance** and **double-sided rubber contact seals (2RS)**. The 2RS contact seals offer superior, maintenance-free protection, actively locking out moisture and road debris while retaining the crucial internal lubrication. The **C3 clearance** is greater than normal, a design feature critical for A/C bearings to compensate for the significant thermal expansion that occurs in hot engine compartments. With its precise dimensions of 32 x 52 x 20 mm and an outer ring width of 18 mm, the RA-32520020/18 RICH offers a high-quality, direct interchange for references such as the INA L32/52 2RSOH03, guaranteeing dependable function of the A/C system.

Key Performance Advantages:

• C3 Internal Clearance: Optimized to prevent bearing binding and failure due to thermal expansion in high-temperature conditions.
• Contact Sealing (2RS): Provides robust, maximum defense against moisture and fine particle contaminants, ensuring longevity.
• A/C Specialized: Double row angular design efficiently handles the high combined radial and axial clutch loads.
• Precision Fit: Manufactured to exact specifications (32x52x20 mm) for reliable interchangeability with INA and NTN references.

Transparency Note

The RA-32520020/18 bearing is manufactured by RICH in China to meet stringent quality and dimensional standards, ensuring reliable interchangeability and performance.
