Needle Roller Bearing

Overview

Uni-Drive Needle Roller Bearings are compact, high-performance bearings that use cylindrical needle-shaped rollers with small diameters and extended lengths. Their unique structure provides high load capacity, rigidity, and precision while maintaining a low cross-sectional profile, making them ideal for applications where space and weight reduction are critical.


Product Features

Key Features

  • High Load Capacity in Compact Size – Handles heavy radial loads with minimal bearing space.
  • Low Cross-Section Height – Enables more compact and lightweight machinery designs.
  • Excellent Rigidity & Rotational Accuracy – Long, slender rollers ensure smooth rotation and minimal deflection.
  • Low Inertial Force – Ideal for oscillating and reciprocating motion, providing stable performance at varying speeds.
  • Easy Replacement – Can be used to replace sliding or plain bearings for improved efficiency and reduced friction losses.
  • Wide Range Available – Drawn-cup, solid, cage-guided, and thrust needle types offered to suit different operating conditions.

Applications

  • Automotive transmissions and gearboxes
  • Pumps, compressors, and reduction gears
  • Power tools, robotics, and small precision equipment
  • Construction and agricultural machinery

Size Range & Availability

  • Inner bore diameters: from 3 mm up to 120 mm
  • Outer diameters: up to 150 mm (depending on type)
  • Widths: typically 8 mm – 60 mm
