Deep Groove ball bearings

Bearings sector
Cylindrical roller bearings	Hard disc drive bearings
Spherical roller bearings	Four point bearings
Taper roller bearings	Angular contact ball bearings
Rolling elements	Deep groove ball bearings

Overview
Both rings posses deep grooves with a radius only slightly exceeding the ball radius. Due to this curvature ratio the bearing can support high radial forces as well as axial forces which make them ideal for a wide range of applications.

The form, radius and surface finish of the tracks is critical to the running performance and noise characteristics of these bearings. Taylor Hobson have a range of Form Talysurf systems which are suitable for measuring the form and surface finish characteristics of deep groove ball bearings.
For details see the Form Talysurf links below:

Also of critical importance is the roundness and waviness of the races and rolling elements. Typically these features are measured using roundness instruments as detailed in the Talyrond links below:

Form Talysurf PGI Bearing Measurement Systems
Medium to large capacity systems for highly accurate measurement of surface texture and geometrical features on deep groove ball bearings.

Form Talysurf Inductive systems
Small capacity systems for accurate measurement of surface texture and geometrical features on deep groove ball bearings.

Talyrond 290 / 280 range
Large capacity systems for highly accurate measurement of roundness and harmonics on deep groove ball bearings.

Talyrond 365 / 240 range
Medium capacity systems for highly accurate measurement of roundness and harmonics on deep groove ball bearings.

Talyrond 100 range
Small capacity systems for accurate measurement of roundness and harmonics on deep groove ball bearings.

Wall Thickness Variation

Along with general geometrical features there is also typically a requirement to look at other critical factors which affect the running performance of these bearings. One of the important factors in ball bearing running performance is Wall Thickness Variation. In particular for bearings that are fixed within a housing the wall thickness variation of the inner ring is critical while for bearings located on a shaft the wall thickness variation of the outer ring is critical. Taylor Hobson have dedicated analysis software for measuring wall thickness variation of ball bearing races. For further details contact your local sales representative.
