High Speed Applications Bearing

New bearings for high-speed applications. Single-row angular contact ball bearings are typically used in applications such as screw, scroll or centrifugal compressors  and pumps. A clear trend in compressor and pump applications is to raise the power density by increasing the rotational speed.

We has introduced the ROBUST Series high-speed precision bearings, to transcend limitations in machine tool applications.These bearings maintain cool operating temperatures and are  designed for heat-resistance.  which combines the best designs with superior technologies to offer effective product solutions for the machine tool industry.

The maximum allowable rotational speed for any individual bearing can be determined from two simple equations and the Table II.  These speed limits are considered thermal limits that have been determined from empirical data from many typical applications. The ability of bearings to operate at high speed is further established by the type of lubrication employed. All the limits shown are based on static oil lubrication, with the oil level set at the center of the bottom most ball or roller when standing still. If grease lubrication is desired, then the speed limit is 66% of the oil limit.
