Product Description

What is the specifications of Deep groove ball bearings?

Deep groove ball bearings are the most typical rolling bearings with the characteristics of simply designed structures,convenience in operation and extensive application.They are designed as non-separable bearings.The raceways in both of the rings are in arc groove form which can carry radial load and double directions axial load. They are of features of low friction factor, and high limit rotational speed and they can be applied in the situations where high rotational speed and low noise and low vibration are required. Applications of these bearings can be found in automobiles, machine tools, motors, instruments, construction machinery, railway vehicle, agricultural machinery and other special machinery.

Features	Deep Groove ball bearings are the most popular of all the ball bearing types because they are available in a wide variety of seal, shield and snap-ring arrangements.The bearing ring grooves are circular arcs made slightly larger than the radius of the ball. The balls make point contact with the raceways (elliptical contact when loaded). The inner ring shoulders are of equal height (as the outer ring shoulders). Deep Groove ball bearings can sustain radial, axial, or composite loads and because of simple design, this bearing type can be produced to provide both high-running accuracy and high-speed operation. Standard ball retainers (cages) are made from pressed steel. Machined cages are used in bearing operation at very high speed or for large diameter bearings.
