About Radial Ball Bearings

Radial ball bearings are probably the most widely used and most recognized ball bearing. These bearings have one row of balls (referred to as a single row), which revolves around the ball path. This feature provides another name for the bearings; they are commonly called deep groove ball bearings. Although designed to primarily carry radial loads, a radial ball bearing’s raceways are deep enough that it can also carry reasonable thrust loads. (However, if thrust loads are excessive, an alternative type of bearing should be considered.)

Most ball bearings, including single row, deep groove ball bearings (SRDG), are assembled using the Conrad method of construction. As an historical note, the inventor of this bearing assembly procedure, Robert Conrad, was given British patent no. 12,206 back in 1903, and U.S. patent no. 822,723 in 1906. This method of construction first takes an inner ring and outer ring and places the inner ring inside of the outer. With the rings oriented in the same direction, the inner is positioned so that it touches the outer ring at one point. This creates a crescent-shaped open area between the rings where the proper number of balls of the appropriate size are placed. The inner ring is then snapped into its proper position in relationship to the outer ring. The balls are evenly distributed around the raceway and the retainer is assembled or inserted into place.

Products & Services Related to Radial Ball Bearings

Aerospace Bearings
Aerospace bearings are designed to meet the rigorous demands of aircraft control and aerospace applications.
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.
