NTN NBNTA1625 Thrust Needle Roller Bearing Assembly

The NTN NBNTA1625 is a precision-engineered thrust needle roller and cage assembly designed to handle high dynamic axial loads in demanding applications. This bearing features a spoke-like configuration of small diameter needle rollers that are equally spaced and guided by a hardened steel cage, providing reduced friction, vibration, and noise during high-speed operation.

Key Features:

• 1" bore diameter, 1-9/16" outer diameter, 5/64" width (25.4mm x 39.675mm x 1.984mm)
• Hardened steel cage provides superior strength, rigidity, and heat resistance
• Through-hardened, high-carbon chromium steel needle rollers for durability under heavy loads
• Contoured roller ends optimize contact stress distribution
• Smaller cross-section than standard thrust bearings for use in restricted spaces
• Maximum rotational speed of 11,000 RPM
• Static load capacity of 12,100 lbf and dynamic load capacity of 3,110 lbf

This thrust needle roller assembly transmits thrust loads between two relatively rotating objects while greatly reducing friction. It can be used independently or unitized with lipped washers (such as TRA1625) to serve as raceway surfaces. Commonly used in automotive and truck transmissions, agricultural and construction equipment, pumps, compressors, and two-cycle engines. Meets ANSI/ABMA 21.2 standards for quality assurance.
