Detailed Description

FAG 102570 is a first-generation wheel bearing designed as a sealed, maintenance-free unit with preset internal clearance and permanent lubrication. Its angular contact ball bearing design supports wheel loads while helping maintain smooth, controlled rotation in both front and rear wheel positions. With its 45 mm inside diameter, 83 mm outside diameter, and 45 mm height, this bearing is sized for select Mazda driveline applications where compact packaging and durable sealing are important.

This part is used on 2001-2002 Mazda Millenia rear, 2001-2002 Mazda Millenia front, 1995 Mazda Millenia rear, 1992-1995 Mazda 929 rear, and 1993-1995 Mazda RX-7 rear. Search terms such as Mazda Millenia rear wheel bearing 102570, Mazda 929 rear wheel bearing, and Mazda RX-7 rear wheel bearing 102570 align with this application coverage.

Common Problems This Part Can Address

• Wheel bearing noise such as humming, growling, or rumbling
• Excess wheel play caused by worn bearing surfaces
• Rough wheel rotation from damaged or dry bearings
• Seal failure that allows contamination into the bearing assembly
• Reduced bearing life in high-load or high-heat service

Installation Notes and Tips

Verify the vehicle position, dimensions, and OE reference before installation. Press-fit wheel bearings should be installed with proper bearing service tools to avoid damage to the races or sealing surfaces. Inspect the hub, spindle, and surrounding components for wear or scoring before fitting the new bearing.
