RUKO SLS-SPS Vapor 50,5mm Rodamiento rígido de bolas, una hilera, juntas 2RSR, juego C3, 50x90x20mm

Industrial machinery often suffers from premature bearing failure due to contamination and inadequate lubrication, leading to costly downtime. The RUKO SLS-SPS-vap.-50,5mm-Kugellager is a deep groove ball bearing engineered to provide reliable performance in demanding applications. With its 2RSR rubber seals, it keeps lubricant in and contaminants out, extending service life.

Who is it for

Maintenance professionals and machine builders who need a dependable bearing for electric motors, pumps, gearboxes, and general industrial equipment. Its C3 internal clearance accommodates thermal expansion and interference fits, making it suitable for high-speed or high-temperature conditions.

Main features

• Single row deep groove ball bearing for radial and moderate axial loads
• 2RSR contact seals on both sides for superior protection against dirt and moisture
• C3 radial internal clearance greater than normal, ideal for press fits and temperature differentials
• Pre-greased for life, reducing maintenance requirements
• High carbon chromium steel construction for durability and load capacity

Tips

Ensure the shaft and housing tolerances are correct for the C3 clearance to avoid excessive noise or reduced life. For applications with high axial loads, consider pairing with a bearing that can handle thrust, as deep groove bearings are primarily radial.
