Ball bearings:Thrust ball bearings | Products by Type:Rolling bearings…

High-speed duplex angular contact ball bearings (for axial loads) These are used in back-to-back duplex (DF) arrangement and can support only bi-directional axial loads. They are superior to double-direction thrust angular ball bearings in high-speed properties, with low axial rigidity.

Technical Information: Ball bearing types, selection factors, and bearing …

Consider an ABEC 3 single row, radial ball bearing having 10 balls of 1/16" diameter, 0.330" inner race diameter and 0.452" outer race diameter in a single shield configuration. This means that for a load of P =143 lbs. the rating life of this ball bearing will be one million revolutions and 90% of a group of such ball bearings will be expected to complete or exceed this value.

Modelling of angular contact ball bearings and axial displacements for high-speed spindles …

1/1/2010· This paper presents modelling of moving sleeve and spindle tip displacements in spindle bearing systems equipped with angular contact ball bearings. The balance of axial forces produced in high-speed bearings is examined, with a particular consideration of centrifugal forces, gyroscopic moments, contact deformations, and contact angles.

Hybrid Ball Bearings

Hybrid ball bearings are able to counter all of these negative attributes resulting in a stronger, longer lasting piece of equipment. The balls in these new bearings are either made of silicon nitride or zirconium oxide. They are stronger than steel yet they weigh less resulting in a higher operating speed and increasing efficiency.
