Deep Groove Ball Bearings

Highly versatile, deep groove ball bearings are made in a simple structure. They are suitable for supporting high or very high speeds, radial loads, as well as moderate axial forces, and allow low noise levels and friction torque.
They are available in single or double row, in open version and with seal.



As these are precision components, they strongly influence performance, form, the radius and surface finish of the raceway, roundness and waviness of the latter and of the rolling elements.

Both rings have deep grooves, with a radius slightly greater than the radius of the ball.


Deep groove ball bearings are used in all sectors that require rolling, in particular:

  • farm machines;
  • electric motors;
  • micromechanics;
  • machine tools;
  • precision instruments.

Thrust Ball Bearings

Thrust ball bearings consist of a shaft washer, housing washer and ball row, elements that can be mounted independently as they are separable.
In addition to the construction series with flat washers, there are also construction series with sphered housing washers to compensate for static angular misalignments. These versions are mounted mostly in combination with alignment plates.


Thrust ball bearings come in single direction or double direction; both absorb high axial forces, while they cannot be loaded radially.
Single direction thrust ball bearings absorb axial forces in one direction.
Double direction thrust ball bearings absorb axial forces in both directions.

Thrust ball bearings are suitable for operating temperatures from -30°C up to +150°C, limited by the lubricant.

Self-Aligning Ball Bearings

Self-aligning ball bearings are especially useful due to they ability to withstand loads in both directions. This feature makes them appropriate in cases of high axial forces, in addition to being used to compensate shaft deflections and/or misalignments near the bearing housings.


Self-aligning bearings are available in two versions: open or sealed. In both cases they consist of a double row of balls, one common sphered raceway in the outer ring, and two deep raceway grooves in the inner ring.

There are many advantages with this type of bearing: the excellent coincidence between the balls and the inner ring helps keep friction low, and thus the heat that results from it, even in high speed conditions. This way, the life of the bearings is extended, along with maintenance frequency, which is significantly reduced.
