RUKO SLS-SPS Vapor 55 mm Rolamento rígido de esferas com vedantes de borracha

When rotating shafts run hot, noisy, or wear out too soon, the cause is often a bearing that cannot hold its grease or keep out dirt. The RUKO SLS-SPS Vapor 55 mm deep groove ball bearing solves that with two contact rubber seals and C3 internal clearance, giving you smooth, low-friction rotation in demanding industrial and mechanical applications.

Who is it for

Maintenance technicians, machine builders, and repair workshops who need a dependable single-row bearing for electric motors, pumps, gearboxes, conveyors, and similar equipment with a 55 mm shaft.

Main features

• Deep groove ball bearing, single row, for high radial and moderate axial loads.
• Bore 55 mm, outer diameter 100 mm, width 21 mm.

Tips

Check shaft and housing tolerances before fitting; C3 clearance suits press fits and higher temperatures. Avoid washing the bearing with solvents, as this removes the factory grease.
