Regal Beloit Corp. introduced its Time Saving axial groove (TSAG) in the inner ring bore on the Sealmaster Unitized Spherical Roller Bearing (USRB), designed to allow easy removal and the ability to reuse the shafting with minimal cleanup.

The design utilizes axial grooves at setscrew locations that run the length of the inner ring, eliminating interference with the burr created by the setscrew, the company says.

The TSAG in the inner ring bore aims to provide clearance from the burr and allows for removal in either direction.

In addition, the design reduces damage to the shaft compared to other methods of removing the bearing, lowering the costs associated with repairing the shaft before reuse. It can also eliminate the cost of having to replace the shaft, according to Regal Beloit.

The Sealmaster USRB bearing with TSAG is ideal for bulk material handling/aggregate industry, eliminates shaft damage and speeds up change-out to get operators back up and running quickly, the company says.

“Time is a valuable commodity in plant operation, and countless hours are spent annually removing setscrew-mounted bearings from shafts,” says Ian Rubin, director of customer experience at Regal Beloit. “After the launch of the time-saving axial groove on our large bore mounted ball bearing, we knew implementation on the Sealmaster USRB would provide the same impact to bearing removal simplification and reduction in shaft damage. The design lessens the total downtime required to remove the bearing, saving time and money.”
