Ball Bearing - Spindle Bearings

Spindle ball bearings are single-row large ball bearings characterized by their particular design engineered with either a 15° or a 25° angular contact. They contain raceways in both the inner and outer rings which can be displaced in relation to the bearing axis and in relation to each other. These rings are assembled with a stationary cage, and the balls cannot be dismantled from the ball bearing housing.

Spindle ball bearings are designed to provide the utmost support for a number of different types of loads making them popular mining bearings. The mechanism's loading capacity proportionally increases with the augmentation of the contact angle. Due to the device's eminent and relentless accuracy, these ball bearings are often utilized when there is a need for utmost precision, high bearing capacity, high-speed and an impeccable accuracy. As a result, they are primarily used as machine tool spindle bearings and mining bearings.

 

Models

There are two primary kinds of spindle bearings:

Open Spindle Bearings: These types of spindle bearings contain large balls inside the bearing housing in order to maximize its performance capacity. The external ring in these large ball bearings usually has only one shoulder.

Closed Spindle Bearing: This model has the same external dimensions as open large ball bearings, but is often packed with small balls, reducing the capacity yet increasing the axial rigidity and speed.
