Power Train Components PTHM903210 Tapered Roller Bearing Cup Bearings & Seals

The Power Train Components PTHM903210 is a tapered roller bearing cup (outer race) designed for high-load automotive and industrial applications. This precision-engineered component is manufactured from high-quality steel to deliver superior strength, wear resistance, and long service life in demanding operating conditions.

Key Specifications:

• Outer Diameter: 3.750 inches (95.25mm)
• Cup Width: 0.875 inches (22.23mm)
• Maximum Fillet Radius: 0.030 inches
• Bearing Type: Single Cup (Outer Race)
• Material: Case Carburized Steel

This bearing cup is part of the HM903200 series and is commonly used in wheel bearing assemblies, differential bearings, and axle applications. Tapered roller bearings excel at handling combined radial and thrust loads, making them ideal for automotive axles, transmissions, and heavy-duty equipment. The cup must be paired with a compatible cone (inner race) assembly to form a complete bearing set.

Important: Always replace bearing cups when installing new bearing cones. Never reuse an old race with a new bearing, as worn races can cause premature bearing failure and reduce load capacity. Power Train Components manufactures precision bearings that meet or exceed OEM specifications for reliable performance.
