Product Overview

The 30BGS32G RICH is a highly reliable **Double Row Angular-Contact Ball Bearing** specifically engineered for use in the clutch pulley of an automotive **Air Conditioner (A/C) compressor**. Manufactured by RICH, this robust unit is designed to provide smooth operation while expertly managing the high speeds, radial forces, and bidirectional axial loads typical of A/C systems.

This model is built with two essential features for thermal stability and longevity: **double-sided rubber contact seals (2RS)** and **C3 internal clearance**. The 2RS contact seals offer superior, maintenance-free protection, effectively sealing in the internal high-performance grease while forming an aggressive barrier against moisture, dust, and engine contaminants. The **C3 clearance** is greater than normal, which is crucial for preventing bearing failure by allowing the bearing components to expand safely under the high operating temperatures of the engine bay. With precise dimensions of 30 x 52 x 20 mm, the 30BGS32G RICH serves as a high-quality, direct interchange for references like NSK 30BD5220 and Nachi 30BG S32G02 DST.

Key Performance Advantages:

• C3 Internal Clearance: Optimized for thermal expansion resistance, preventing component binding and extending service life in hot environments.
• Contact Sealing (2RS): Provides maximum defense against water and fine contaminants, ensuring maintenance-free operation.
• A/C Specialized: Double row angular design efficiently handles the high combined loads of the clutch pulley.
• Precision Fit: Manufactured to exact OE specifications (30x52x20 mm) for reliable interchangeability.

Transparency Note

The 30BGS32G bearing is manufactured by RICH in China to meet stringent quality and dimensional standards, ensuring reliable interchangeability and performance.
