Reliable rotation with Skf 61903-2RS1

Practical benefits

Effective protection against contaminants: Dual contact rubber seals keep lubricant securely inside while preventing dust and moisture from entering the raceways.
Smooth and low-friction running: The precision deep grooves minimize friction and vibration so you achieve stable performance at high rotational speeds.
Handles combined directional loads: Designed to support radial and axial loads in both directions, it delivers dependable operation in compact mechanical setups.

In a nutshell

The right choise for

With the Skf 61903-2RS1 single-row deep groove ball bearing, you restore smooth and quiet rotation to your rotating machinery. Featuring a 17 mm cylindrical bore, 30 mm outer diameter, and 7 mm width, this steel bearing is well suited for maintaining electric motors, power tools, and drive assemblies. Its dual contact rubber seals (2RS1) retain the lubricant inside while shielding raceways from dust and moisture contamination. Designed to handle both radial and axial loads in either direction with standard cn radial internal clearance, it effectively eliminates vibration and mechanical play for dependable service life.

Product description

Single row deep groove ball bearings with seals or shields are particularly versatile, have low friction and are optimized for low noise and low vibration, which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than many other bearing types. The integral sealing can significantly prolong bearing service life because it keeps lubricant in the bearings and contaminants out.

Integral sealing prolongs bearing service life
Simple, versatile and robust design
Low friction and high-speed capability
Accommodate radial and axial loads in both directions
Require little maintenance
