Do you know the 6203 2rs c3 bearing mean?

• Deep-groove geometry for high speeds and supporting both radial and axial loads
• Shields on both sides of the bearing to keep lubricant in and contaminants out
• Normal radial internal clearance for applications that do not involve thermal expansion or atypical precision
• Pressed steel cage evenly spaces the balls for even load distribution and prevents contact to reduce friction, vibrations, and noise

6203 2rs c3 bearing is the basic model of bearing, which refers to the single-row deep groove ball bearing, which is the most common type of rolling bearing. The single-row deep groove ball bearing type code is 6, and the double-row deep groove ball bearing code is 4. Generally, it consists of an outer ring, an inner ring, a group of steel balls and a group of cages.

6203 2rs c3 bearing mainly bears radial load, and can also bear both radial load and axial load. When it only bears radial load, the contact angle is zero. When the 6203 2rs c3 bearing has a large radial clearance, it has the performance of angular contact bearing and can bear a large axial load. The friction coefficient of the 6203 2rs c3 bearing is very small and the limit speed is also very high.

The method of clearance adjustment is determined by the bearing type, which can be generally divided into bearings with non-adjustable clearance and adjustable clearance.

Bearing with non-adjustable clearance means that the clearance of the bearing is determined after the bearing leaves the factory. The well-known deep groove ball bearings, self-aligning bearings and cylindrical bearings all belong to this category. For the clearance of non-adjustable bearings 6203 2rs c3 bearing, the industry has corresponding standard values (C0, C3, C4, etc.), and a specific clearance range can also be customized. When the dimensions of important official and bearing seat are known, the matching amount of inner and outer rings is determined, and the clearance after installation cannot be changed. Because the matching amount is a range in the design stage and the final clearance also exists a range, it is not applicable in applications that require clearance accuracy.
