Timken M88010 Tapered Roller Bearing Cup

Product Description

The TIMKEN M88010 is a tapered roller bearing cup - the outer ring component of a tapered roller bearing assembly - engineered to handle both radial and axial (thrust) loads simultaneously. The cup seats in the housing bore and provides the hardened raceway surface against which the tapered rollers travel. Built to TIMKEN's manufacturing standards, this cup delivers reliable performance in high-load, variable-speed applications. It measures approximately 2.89 inches in length, 2.86 inches in height, and 1.11 inches in width, and weighs 0.369 pounds. Installation is typically performed by drivetrain and axle technicians in automotive or light-truck service settings.

The M88010 cup is designed for front axle and pinion applications across a range of vehicles. Documented fitment includes Audi cars from 1986 to 1988, BMW 3 Series cars from 1988 to 1991, Mitsubishi trucks from 1989 to 2008, and Porsche vehicles from 1990 to 2000 in 4WD front axle configurations. It is sold as a single unit and is intended to be replaced together with its matching cone (inner race) to restore full bearing assembly integrity and service life.

Key Features

• Outer cup ring engineered to manage combined radial and axial loads
• Hardened raceway surface designed for durability under heavy drivetrain loads
• Compact geometry: 2.89 x 2.86 x 1.11 inches, weighing 0.369 pounds
• Sold individually (quantity 1 per package)
• Designed for use in front axle and pinion positions in light automotive and truck applications

Compatibility

Documented fitment includes Audi cars (1986-1988), BMW 3 Series cars (1988-1991), Mitsubishi trucks (1989-2008), and Porsche vehicles (1990-2000) in 4WD front axle configurations. Always verify the matching cone part number before installation to ensure proper bearing assembly pairing.

Installation Notes

Bearing cup replacement is typically performed by a licensed automotive or drivetrain technician. Disconnect power and secure the vehicle before beginning axle disassembly. The cup should always be replaced together with its matching cone to maximize service life and prevent premature failure. Press the cup squarely into the housing bore using an appropriate bearing driver or hydraulic press - never drive it in at an angle or strike it directly with a hammer.
