Product Overview

The 32BG04S3G RICH is a specialized **Double Row Angular-Contact Ball Bearing** designed for critical operation within the automotive **Air Conditioner (A/C) compressor clutch**. Manufactured by RICH, this lightweight unit is built to manage the unique stresses of A/C systems, including the high speeds and the combined radial and axial loads generated by the clutch pulley and belt tension.

This bearing is engineered with two performance features essential for A/C use: **C3 internal clearance** and **two-sided rubber, non-contact seals** (often designated 2RSL or similar). The C3 clearance is greater than normal, which is crucial for preventing binding and premature failure caused by the significant thermal expansion experienced in a hot engine bay. The non-contact seals effectively guard against dust and moisture while minimizing rotational friction, supporting the high-speed demands of the compressor. With precise dimensions of 32 x 47 x 18 mm, the 32BG04S3G RICH is a reliable, high-quality interchange for references like Nachi 32BG04S3G-2DL and NSK 32BD4718DU.

Key Performance Advantages:

• C3 Internal Clearance: Optimized for A/C clutch use to accommodate thermal expansion and prevent binding.
• Non-Contact Sealing: Provides necessary contamination protection with reduced friction for cooler, high-speed performance.
• A/C Specialized: Double row angular design efficiently handles the combined radial and axial loads of the clutch pulley.
• Precision Fit: Manufactured to exact OE specifications (32x47x18 mm) for reliable interchangeability.

Transparency Note

The 32BG04S3G bearing is manufactured by RICH in China to meet stringent quality and dimensional standards, ensuring reliable interchangeability and performance.
