NTN NBHM88542 Differential Pinion Bearing Tapered Roller

The NTN NBHM88542 is a high-quality tapered roller bearing cone designed specifically for differential pinion applications in automotive drivetrains. This precision-engineered bearing is built to handle the demanding combination of radial and axial loads encountered in differential assemblies, providing reliable performance under severe operating conditions.

Key Specifications:

• Bore diameter: 1.25 inches (31.75mm)
• Width through bore: 1.0938 inches (27.783mm)
• Chrome steel race construction for durability
• Stamped steel cage for roller retention and spacing
• Dynamic load rating: 103,000N
• Static load rating: 111,000N

Design Features:

• Single cone (inner ring) assembly with tapered rollers
• Separable design allows for easy installation and maintenance
• Precision tapered rollers evenly distribute loads to reduce friction and wear
• Low-friction operation ensures smooth performance and extended service life
• Manufactured to OE quality standards for reliable fitment

This bearing is commonly used in front and rear differential pinion configurations across a wide range of vehicles. The NTN NBHM88542 is equivalent to industry standard HM88542 and is interchangeable with other manufacturers using this designation. When replacing differential bearings, it's recommended to replace both the cone and cup (outer ring, sold separately) as a complete set for optimal performance.
