High Performance Bearings
Needle roller bearings are a specialized type of bearing engineered for high performance in applications where space is limited and heavy radial loads must be supported. Unlike traditional ball bearings, needle bearings use long, thin cylindrical rollers which increases contact surface area and maximizes radial load capacity while minimizing cross-sectional height.
At Ritbearing, we carry various high quality needle roller bearings engineered by leading manufacturers to meet your specific application needs.
What Is A Needle Bearing?
A needle bearing is a form of roller bearing characterized by its small diameter, cylindrical rollers. These rollers reduce friction between moving parts and support high radial loads in a compact design. Because of their narrow profile and high load-handling capability, needle bearings excel in applications with limited radial space where conventional bearings are too bulky.
Key Features of Needle Bearings:
- High radial load capacity, despite a low profile
- Slim cross-section ideal for tight installation spaces
- Multiple configurations, including single row, double row, solid, or split cage types
- Available in inch and metric sizes, with open or closed ends
- Offered in open, single seal (U) or double sealed design (UU)
- Relubrication holes are available on larger sizes (above 10 mm bore)
- A limited range is offered in AISI 440C Stainless Steel
- Excellent performance in oscillating motion applications
Needle Bearing Types
Needle roller bearings come in a variety of styles depending on the application:
- Drawn Cup Needle Bearings: Lightweight outer rings, great for space-restricted designs
- Machined Ring / Solid Needle Bearings: Enhanced rigidity for higher loads
- Caged Needle Bearings: Rollers guided by a cage for improved lubrication and speed performance
- Full Complement Needle Bearings: Maximum load capacity with more rollers and no cage
- Cam Type Track Roller / Cam Follower: Specialized needle configurations for guiding cam and track elements
- Thrust Needle Roller Bearings: Engineered to handle axial loads, rather than radial loads, and manufactured with a compact, flat design
Common Applications for Needle Bearings
- Automotive
- Lawn and Garden Equipment
- Machine Tool
- Oil & Gas
- Power Tools
- Primary Metals
- Printing Machines
- Semiconductor
