CGB Precision Products (www.cgb.com.au), a specialist supplier of super precision ball bearings and related components, has announced that it is offering a series of Barden precision bearings, such as angular contact bearings for machine tooling applications.
With one ring shoulder totally or partially removed, angular contact bearings ensure higher speed capabilities and greater load capacity by allowing larger ball complement than those found in comparable deep groove bearings.
The spindle bearings are assembled to a contact angle by altering the radial clearance and feature nominal contact angles of either 15º or 25º, which enables them to deliver improved radial rigidity and capacity.
The angular contact bearings are available in two variants — non-separable and separable.
In a separable bearing, the cage keeps the balls in place to separate the outer ring assembly, which holds the cage and the balls, from the inner ring.
Ideal for use in applications where bearings must be integrated in blind holes, the separable angular contact bearings are also used in applications where press fits are needed both in the housing and on the shaft.
The separable variant of angular contact bearings permit a dynamic balance between a rotating component and an inner ring mounted in place, and the housing and the outer ring.
Angular contact bearings support combinations of thrust and radial loading or thrusts loads alone. Angular contact bearings, however, do not accept radial loads only.
