About Needle Roller Bearings

Needle roller bearings are roller bearings, which have a high load carrying capacity with a very small section height. They are available with or without an inner ring.  In all needle roller bearings, except for full complement needle roller bearings, the needle rollers themselves are guided parallel to the axis by a dimensionally stable cage.   Airframe needle roller bearings are specified by MIL-B-3990 and National Academy of Sciences (NAS) standards.

Radial airframe bearings are designed for static loads and oscillation or slow rotation. They consist of an inner and outer ring with a full complement of needle rollers in a single or double row. These bearings must be supported by housings and mounted on high-strength shafts for maximum load capacity. Self-aligning designs can typically accommodate up to ±5° of dynamic misalignment.

Products & Services Related to Needle Roller Bearings

Aerospace Bearings
Aerospace bearings are designed to meet the rigorous demands of aircraft control and aerospace applications.
Angular Contact Bearings
Angular contact bearings are designed so that a contact angle between the races and the balls is formed when the bearing is in use.
Ball Bearings
Ball bearings are used to provide smooth, low friction motion in rotary applications. Ball bearings types include radial ball bearings (deep groove and angular contact) and thrust ball bearings.
Insert Bearings
Insert bearings and wide inner ring bearings mount to shafts via setscrews or locking collars.
Miniature Bearings and Instrument Bearings
Miniature bearings and instrument bearings carry moderate radial and thrust loads at low operating torque while providing high performance in a small envelope design. These types of bearings are single row ball bearings available in up to 1 1/8" outer diameter (OD) sizes
Roller Bearings
Roller bearings are used in rotary applications to replace sliding movement with low friction, rolling motion. The principal types of roller bearings are cylindrical, spherical, and tapered.
Thin-section Bearings
Thin-section bearings have small cross-sections with respect to their diameter.
