Product Overview

The 30BD6227 RICH is a specialized **Double Row Angular-Contact Ball Bearing** specifically engineered for rugged use within the **Air Conditioner (A/C) compressor clutch** assembly. Manufactured by RICH, this unit is built to withstand the high rotating speeds, heavy radial forces, and significant thermal expansion encountered in the hot environment of the engine bay.

This model features two essential components for superior reliability: **double-sided rubber contact seals (2RS)** and **C3 internal clearance**. The 2RS contact seals provide a superior, maintenance-free barrier, aggressively sealing out moisture, road grime, and contaminants while ensuring the high-performance internal grease remains effective. The **C3 clearance** is greater than normal, which is critical for A/C bearings as it prevents the components from binding and failing prematurely due to expansion under high operating temperatures. With precise dimensions of 30 x 62 x 26.99 mm, the 30BD6227 RICH offers a high-quality, dependable direct interchange for references like Koyo BD30-11A and NSK 30BD6227.

Key Performance Advantages:

• C3 Internal Clearance: Optimized to prevent bearing failure caused by thermal expansion in high-temperature environments.
• Contact Sealing (2RS): Provides maximum defense against water and fine contaminants, ensuring longevity.
• A/C Specialized: Double row angular design efficiently handles the high combined loads of the clutch pulley.
• Precision Fit: Manufactured to exact specifications (30x62x26.99 mm) for reliable interchangeability.

Transparency Note

The 30BD6227 bearing is manufactured by RICH in China to meet stringent quality and dimensional standards, ensuring reliable interchangeability and performance.
