SKF BR111 Automatic Transmission Pinion Bearing - Front

SKF BR111 Automatic Transmission Pinion Bearing

SKF BR111 is an automatic transmission pinion bearing built for front-position applications on select Audi models. With precise dimensions and a tapered roller design, it supports smooth, quiet operation in transmission service where bearing fit and surface finish matter.

Key Features

• Inside diameter: 1.378 in.
• Outside diameter: 2.441 in.
• Width: 0.657 in.
• Tapered roller bearing set design for transmission use
• Logarithmic roller raceway profile with a smooth surface finish
• Engineered for consistent rotation and reduced noise

Detailed Description

The SKF BR111 automatic transmission pinion bearing is specified for front applications on 1990-1995 Audi 100, 1991-1992 Audi 80, 1991 Audi 90, 1993-1995 Audi 90, and 1992-1994 Audi 100 Quattro. This part number, BR111, is built around a tapered roller bearing construction that helps maintain accurate support under transmission loads while promoting quiet operation. The listed dimensions—1.378-inch inside diameter, 2.441-inch outside diameter, and 0.657-inch width—are important for proper bearing selection and fitment in the transmission assembly.

SKF has more than a century of engineering and manufacturing experience, and its bearing products are produced to strict quality standards for durability and safety. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Bearing Helps Address

• Transmission bearing noise from worn pinion support surfaces
• Excessive play or looseness in the pinion bearing location
• Rough rotation caused by bearing wear or surface damage
• Fitment issues when replacing a front transmission pinion bearing on Audi 100, Audi 80, or Audi 90 models
• Restoration of proper bearing support during transmission service

Installation Notes and Tips

Verify the inside diameter, outside diameter, and width against the removed bearing before installation. Confirm front-position fitment for your vehicle and compare the application details for 1990-1995 Audi 100, 1991-1992 Audi 80, 1991 Audi 90, 1993-1995 Audi 90, or 1992-1994 Audi 100 Quattro. Clean the bearing bore and surrounding components thoroughly, and inspect related transmission parts for wear before assembly. Use proper bearing installation practices to avoid damage to the raceways and rolling elements.

Quality Assurance

SKF manufactures this bearing to high quality standards with a focus on long service life, smooth operation, and safety. The tapered roller design and refined raceway profile reflect SKF’s established bearing engineering approach for transmission service.
