Product Features
- Single-row deep groove ball bearing design supports radial loads and moderate axial loads in both directions. Simple and robust construction requires little maintenance and is suitable for high-speed applications.
- Open design allows for easy lubrication and maintenance in transmission applications.
- Manufactured to OE specifications with chrome steel rings and balls, and a pressed steel cage for durability and fatigue resistance.
- Direct interchange with multiple major brand equivalents including SKF 6309-Z, NTN 6309ZZ/5K, and NSK 6309ZZCMP6.
- Designed for transmission input shaft positions requiring high reliability and moderate load capacity.
- Available for product customization – logo, code, pattern, or words can be applied to the bearing or packaging.
Installation Notes
- Confirm bore diameter (45.00 mm) and outer diameter (100.00 mm) match your housing and shaft before installation.
- This is an open bearing – pack with high-quality grease or transmission oil compatible with the application before installation.
- Inspect the housing and shaft surfaces for wear or damage before installing new components.
- Apply even pressure when pressing the bearing into the housing or onto the shaft – never apply force directly through the rolling elements. Do not use a hammer to strike the bearing.
- Install in a clean environment to prevent contamination. Even small particles entering the bearing can shorten its service life.
- Refer to the vehicle or transmission service manual for torque specifications and installation procedures.
