About Aerospace Bearings

Aerospace bearings are designed to meet the rigorous demands of aircraft control and aerospace applications. They are usually manufactured in accordance with U.S. government military specifications (MIL-SPEC) and made from stainless steel or other metals or materials that are resistant to corrosion, shock, and temperature extremes. Aerospace bearings are available in several different shapes and with varying load and axial load capacities. Important measurements for Aerospace bearings include bore size, outside diameter, and overall width. Metric and English or imperial pitch bearings are available. Typically, manufacturers use a standard numbering system for bearings with metric diameter bores. For bore sizes 04 and up, multiplying the size by 5 yields the bore in millimeters. Hexagonal bores are measured across the flats. Tapered bores are measured by the smaller diameter.

Products & Services Related to Aerospace Bearings

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

Needle Roller Bearings

Needle roller bearings are designed for radial load applications where a low profile is desired.

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.
