Solve Industrial Motion Group has acquired SST Bearing Corporation (“SST Bearings”), a worldwide supplier and manufacturer of bearings and power transmission components.

Four-Point Bearings Do Triple Duty While Saving Space

March 1, 2015

A four-point contact ball bearing makes it easy to simplify machine designs that combine radial, thrust and moment loads, because it can handle all three simultaneously. They are primarily used for slow-to-moderate-speed applications, or where oscillatory movement is predominant.

Study of Multiple-Point Oil-Jet Lubrication of High-Speed Ball Bearings

June 1, 2014

The air-oil, two-phase flow inside the multiple-point, oil-jet lubrication ball bearing was studied based on CFD (computational fluid dynamics) theory and technique, and compared with single-point, oil-jet lubrication. The results indicate that the air-oil distribution inside the bearing with multiple-point, oil-jet lubrication is more uniform than single-point injection.

How To Use a Hand-Held Micrometer to Measure Miniature and Instrument Ball Bearings

December 1, 2013

For the most accurate measurements, miniature and instrument ball bearing dimensions should be measured with a calibrated air gauge. A good second option is a calibrated optical comparator. On occasion, it may be necessary to use a calibrated, hand-held micrometer to double-check a measurement or for simple verification while working in the field.

Radial Play (Internal Clearance in Ball Bearings)

August 1, 2011

At first glance, ball bearings are relatively simple mechanisms. However, an analysis of their internal geometries reveals that they are quite complex. For example, the ball to raceway conformity, the radial play, and the number of balls all impact the ability of a ball bearing to support loads under a variety of conditions.
