SKF BR25578 Tapered Roller Bearing Cone Differential Carrier Bearing

The SKF BR25578 is a single-row tapered roller bearing cone designed for differential carrier and drivetrain applications. The cone assembly — comprising the inner ring, tapered rollers, and cage — pairs with a separately sold cup (outer ring) to form a complete tapered roller bearing assembly.

Key Specifications:

• Inside Diameter: 1.687 in
• Outside Diameter: 3.265 in
• Width: 1.000 in
• Type: Single-Row Tapered Roller Bearing Cone
• Sub Type: Differential Carrier Bearing

Features & Benefits:

• Conical inner ring raceway and tapered rollers enable the bearing to handle both radial and axial (thrust) loads simultaneously
• Precision geometry minimizes sliding between raceways and rollers, reducing wear and extending service life
• Separable cone and cup design allows for easy installation and precise adjustment of end play or preload during assembly
• Manufactured to SKF's OE-quality standards for reliable performance in demanding drivetrain environments
• Open configuration supports in-place lubrication and maintenance
