 Inch and Metric Ball Bearings -Image

SPB-USA is a recognized leader in the manufacturing of precision miniature and medium-size bearings in inch and metric dimension. All bearings are available in 52100 Chrome Steel or 440 Stainless Steel.

Our sizes range from .06mm Bore Diameter to 90mm Bore Diameter, and 0.0400 to 0.7500 inch Bore Diameter.  A variety of closures and lubrications are available to meet demanding applications, such as AC/DC motors, power tools, encoders, flow meters, pumps, measuring devices, office automation products, medical equipment, and many other special applications too numerous to mention.

 

Design & Characteristics of Radial Ball Bearings include:

Load

Single row radial ball bearings with balls separated by a cage can support radial loads, axial loads and tilting moments. A full complement V-type ball bearing can support only radial loads and some low axial loads.

Speed

Maximum permissible speeds for ball bearings are mainly related to the bearing design and size, cage type, bearing internal clearance, method and type of lubrication, manufacturing accuracy, sealing methods and loads.

Torque and Noise Level

Single row radial ball bearings are precision components and have low torque and noise levels.

Inclination of Inner/Outer Rings

Shaft and housing seats with poor accuracy, fitting errors and shaft bending might cause inclination between the inner and outer rings although the internal clearance of the bearing will permit this to a certain extent.
Generally, the maximum permissible inclination between the inner and outer, rings is approximately l in 300.

Toughness

Bearings under load deform elastically at the contact point between the rolling element and bearing ring. This in influenced by the bearing type, size, form and load.

Installation & Removal

The single row radial ball bearing is a non-separable bearing.
Therefore, shafts and housings should be so designed to enable bearing inspection and replacement when necessary.

Axial Location

Improved axial location is obtation with NR and F-type bearings.
