Angular Contact Ball Bearings

Angular contact ball bearings can carry both Radial and Axial loads. These loads are transferred from one raceway to the other through the bearing balls along a specifically designed contact angle. GMN inventories both 15°(C) and 25°(E) contact angles, but many specials are available when the application demands. It is GMN’s philosophy to offer the best possible bearing for each application. This can be achieved by explicitly specifying each aspect of the Spindle Bearing to fulfill a particular application’s requirement.

Precision Angular Contact Ball Bearings for Machine Spindles

GMN is a worldwide leading producer of high frequency machine spindles, so we know firsthand the demands in modern bearing systems. Using our angular contact ball bearings (sometimes called spindle bearings), with grease lubrication in particular, many spindles reach the highest processing speed at low production and maintenance costs. GMN can offer an additional increase in speed by using our hybrid ball bearings.

Range of Angular Contact Bearing Series

GMN’s “S” bearing Series exceeds most requirements in speed ability, load capacity and both radial and axial stiffness. However, as technology progresses so does GMN to keep pace with the multitude of applications that require Super Precision Bearings. With this in mind GMN can offer multiple bearing series to meet one’s application:
