Product Overview:
The 30BCS36-2MT2N C3 RICH is a high-performance single row deep groove ball bearing specifically developed for automotive transmission and differential applications. This component is an essential replacement part for Toyota and Subaru vehicles, engineered to match the precise tolerances of the original equipment. It features double-sided contact rubber seals that provide an airtight barrier against moisture, road salt, and fine particles, preserving the high-quality internal lubricant. The outer ring is equipped with a dedicated groove for a snap ring, ensuring a secure axial lock within the bearing housing. With C3 internal clearance, this bearing is designed to maintain smooth rotation and prevent seizure during the intense thermal expansion typical of long-distance driving and heavy-load conditions.
Key Performance Advantages:
- Maximum Contamination Protection: Double-sided contact seals (2MT/2RS) offer superior resistance to environmental ingress compared to standard shields.
- Thermal Expansion Management: C3 clearance provides the necessary internal space to handle high-temperature gearbox environments.
- Secure Housing Integration: The outer ring groove ensures stable positioning and prevents axial migration under vibration.
- Multi-Brand Compatibility: Precision-engineered to meet the strict technical standards of both Toyota and Subaru drivetrain systems.
Transparency Note: This bearing is manufactured under the RICH brand. The code 30BCS36-2MT2N C3 and the OE references listed are used solely for identification and do not imply affiliation with other manufacturers.
