Product Overview

The 30BG04S22 RICH is a specialized **Double Row Angular-Contact Ball Bearing** designed for critical operation within the **Air Conditioner (A/C) compressor clutch** assembly. Manufactured by RICH, this unit is engineered to manage the demanding combination of high-speed rotation, significant thermal expansion, and the heavy combined radial and axial loads imposed by the clutch pulley.

This model features two essential components for reliable performance: **double-sided rubber contact seals (2RS)** and **C3 internal clearance**. The 2RS contact seals offer superior, maintenance-free protection, effectively sealing out water, dust, and road grime while retaining the high-performance internal grease. The **C3 clearance** is greater than normal, which is a crucial design feature for A/C bearings to compensate for the significant thermal expansion that occurs in the high-heat environment of the engine bay, preventing bearing binding and premature failure. With precise dimensions of 30 x 45 x 18 mm, the 30BG04S22 RICH offers a reliable, high-quality direct interchange for references like NSK 30BD4518T12DDUKCG21.

Key Performance Advantages:

• C3 Internal Clearance: Optimized to resist failure caused by thermal expansion in hot engine environments.
• Contact Sealing (2RS): Provides maximum defense against water and fine contaminants, ensuring maintenance-free longevity.
• A/C Specialized: Double row angular design efficiently handles the high combined loads of the clutch pulley.
• Precision Fit: Manufactured to exact specifications (30x45x18 mm) for reliable interchangeability.

Transparency Note

The 30BG04S22 bearing is manufactured by RICH in China to meet stringent quality and dimensional standards, ensuring reliable interchangeability and performance.
