Product Overview

The RA-30470020 RICH is a specialized **Double Row Angular-Contact Ball Bearing** specifically engineered for rugged use within the automotive **Air Conditioner (A/C) compressor clutch**. Manufactured by RICH, this unit is built to manage the high radial forces, bidirectional axial loads, and thermal expansion inherent to A/C clutch operation.

This model is equipped with two critical features for reliable performance: **double-sided rubber contact seals (2RS)** and **C3 internal clearance**. The 2RS seals offer superior, maintenance-free protection, aggressively keeping out abrasive contaminants like road dust and moisture while retaining the internal high-performance grease. The **C3 clearance** is greater than normal, which is essential in a hot engine environment as it prevents the bearing components from binding when they expand due to high operating temperatures. With precise dimensions of 30 x 47 x 20 mm, the RA-30470020 RICH offers a high-quality, direct interchange for references like Nachi 30BG04S21-2DST, ensuring the quiet and dependable function of the A/C system.

Key Performance Advantages:

• C3 Internal Clearance: Optimized for thermal expansion resistance, crucial for A/C clutch operation in hot environments.
• Contact Sealing (2RS): Provides robust, maximum defense against moisture and fine particle contaminants.
• A/C Specialized: Double row angular design efficiently handles the combined radial and axial loads of the clutch pulley.
• Precision Fit: Manufactured to exact specifications (30x47x20 mm) for reliable interchangeability.

Transparency Note

The RA-30470020 bearing is manufactured by RICH in China to meet stringent quality and dimensional standards, ensuring reliable interchangeability and performance.
