Timken 41286 Tapered Roller Bearing Single Cup 2.8593 Inch OD

The Timken 41286 is a single cup (outer ring) component of a tapered roller bearing assembly from Timken's 41000 Series. This precision-engineered cup pairs with a matching cone (inner ring assembly, sold separately) to create a complete single-row tapered roller bearing capable of supporting both radial and axial loads in demanding industrial applications.

Key Specifications:

• Outside Diameter: 2.8593 inches (72.625mm)
• Cup Width: 0.6875 inches (17.462mm)
• Precision Level: ABMA Class 2 (Standard Tolerance)
• Material: High-alloy steel construction
• Operating Temperature Range: -54°C to 120°C (-65°F to 250°F)
• Configuration: Open design for field lubrication
• Standard: Meets ISO 355 and ABMA 19.2 standards

Features and Benefits:

• Separable design allows for easy installation and precise adjustment of bearing preload
• Tapered roller geometry efficiently distributes loads along roller length, minimizing friction
• High-alloy steel construction provides exceptional durability and heat tolerance
• Resists deformation under heavy loads and extreme operating conditions
• Open configuration enables field lubrication and maintenance flexibility
• Typically mounted in opposing pairs on shafts to evenly distribute radial and thrust loads

Timken tapered roller bearings are widely used across automotive, construction equipment, agricultural machinery, gearboxes, wheel hubs, industrial machinery, and power transmission applications where reliability and precision are critical. The 41286 cup must be matched with an appropriate cone based on load requirements and thermal expansion considerations.
