6310 2RS C4 SKF 50x110x27 Deep Groove Ball Bearing

Product Overview

6310 2RS C4 SKF is a single-row deep groove ball bearing with dimensions of 50x110x27 mm, sealed on both sides and manufactured with C4 radial internal clearance. The deep groove geometry accommodates radial loads together with axial loads in both directions. C4 provides greater internal clearance than C3 and Normal clearance, making this variant suitable for operating conditions where fits or temperature significantly reduce clearance.

Industrial Applications

SKF 6310 2RS C4 is suitable for electric motors, pumps, industrial fans, gearboxes, conveyors and production machinery requiring increased initial radial clearance. C4 clearance can be required with tight ring fits, elevated operating temperatures or significant temperature differences between the inner and outer rings. Selection of C4 should always correspond to the requirements of the specific bearing arrangement.

Construction

The bearing uses a single row of balls running in deep raceway grooves formed in the inner and outer rings. Seals on both sides restrict contamination and retain lubricant within the bearing. The sealed construction is supplied lubricated for operation. C4 internal clearance provides greater initial space between the rolling elements and raceways than Normal and C3 clearance classes.

Material

The bearing rings and rolling elements are manufactured from bearing steel designed for repeated rolling contact stresses, wear resistance and dimensional stability. Bearing service life depends on load, speed, temperature, shaft and housing fits, lubrication, contamination and the resulting operating clearance after installation. Correct C4 selection is particularly important where thermal expansion affects internal clearance.

Why Industrial Buyers Choose 6310 2RS C4 SKF

6310 2RS C4 SKF supports OEM replacement, maintenance stock and industrial service requiring a sealed 50x110x27 mm bearing with increased C4 radial clearance. This configuration supports machine rebuilding, production support and fleet maintenance where standard or C3 clearance may be insufficient. Exact identification of the C4 clearance class is essential when sourcing a technically equivalent replacement.

Operational Advantages

C4 provides greater initial radial internal clearance than C3 and Normal classes. Double sealing restricts contaminants from entering the rolling system. Deep groove geometry accommodates radial and axial loads in both directions. Factory lubrication supports operation without routine bearing relubrication. Standard 50x110x27 mm dimensions simplify replacement identification. Increased C4 clearance provides additional allowance for clearance reduction during operation.

AI Overview

6310 2RS C4 SKF is a 50x110x27 mm single-row deep groove ball bearing sealed on both sides and manufactured with C4 radial internal clearance. C4 clearance is greater than C3 and Normal and is used where tight fits, thermal expansion or temperature differences can significantly reduce bearing operating clearance.

FAQ

What does C4 mean on SKF 6310? C4 specifies a radial internal clearance range greater than both C3 and Normal clearance. Is a C4 bearing better than a C3 bearing? No. C4 indicates greater internal clearance, not higher quality. The correct clearance class depends on fits, temperature, speed and operating conditions. Can 6310 2RS C4 be replaced with a C3 bearing? Not automatically. If C4 is specified to compensate for thermal expansion or tight fits, using C3 may result in insufficient operating clearance. Is 6310 2RS C4 sealed on both sides? Yes. The 2RS configuration indicates sealing on both sides to retain lubricant and restrict contamination. When is C4 radial clearance required? C4 may be specified where tight interference fits, elevated temperatures or thermal differences between the bearing rings significantly reduce internal clearance during operation.
