BB1-0078 PFI Deep Groove Ball Bearing 22x52x15 mm

What is the BB1-0078 PFI Bearing?

The BB1-0078 PFI is a single row deep groove ball bearing designed primarily for automotive gearbox applications. Its deep raceway geometry allows it to support radial loads together with moderate axial loads in both directions while maintaining smooth operation at high rotational speeds. The bearing is factory lubricated and equipped with double-sided contact rubber seals, providing maintenance-free performance and reliable protection against dust, moisture and contaminants.

Construction and Operating Principle

The BB1-0078 belongs to the family of single row deep groove ball bearings used in automotive transmissions and rotating equipment.

Key design features include:

• Single row deep groove ball bearing
• Factory pre-lubricated
• Double-sided contact rubber seals (2RS type)
• Steel cage
• Cylindrical bore
• Maintenance-free under normal operating conditions

The deep groove raceway enables low-friction operation while efficiently supporting both radial and moderate axial loads, making the bearing suitable for high-speed automotive applications.
