Smooth rotation with Skf 6303-2RSH/C3

Practical benefits

Dual contact rubber seals: The rubber seals on both sides keep lubricant inside while preventing dirt, dust, and moisture from entering the bearing.
Enhanced internal C3 clearance: The expanded C3 radial clearance allows you to handle thermal expansion effortlessly during high-speed applications.
Versatile load carrying capacity: This single-row deep groove ball bearing smoothly supports both radial and axial loads with minimal friction and noise.

In a nutshell

The right choise for

Keep your rotating equipment running smoothly and reliably with the Skf 6303-2RSH/C3 single-row deep groove ball bearing. Designed for a 17 mm cylindrical bore with a 47 mm outside diameter and 14 mm width, it handles both radial and axial loads with minimal friction and vibration. The enlarged C3 internal clearance easily accommodates thermal expansion during high-speed applications in electric motors, drive shafts, and pumps. With contact rubber seals on both sides, factory grease stays locked inside while dust and moisture are kept out, ensuring long service life and maintenance-free performance.

Product description

Single row deep groove ball bearings with seals on one or both sides 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 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
