Deep Groove Ball Bearings SKF 6312 -2RS1

The SKF 6312-2RS1 deep groove ball bearing, measuring 60x130x31 mm, offers reliable protection against dirt thanks to sliding seals on both sides.

The 6312 -2RS1 deep groove ball bearing is a single-row radial ball bearing from SKF Rolling Bearings that can accommodate radial loads as well as moderate axial forces. The component has the following main dimensions: 60 mm bore, 130 mm outer diameter and 31 mm width. As they are manufactured from standard rolling-bearing steel 100Cr6, the inner ring, outer ring and rolling elements are characterised by dimensional stability in continuous industrial use. The sealed design supports operation in contaminated environments and protects against external influences.

What is the 6312-2RS1 deep groove ball bearing suitable for in mechanical engineering?

This radial deep-groove ball bearing is suitable for bearing arrangements subject to primarily radial forces and axial guidance of the shaft in both directions. The outer ring is designed without a flange or groove, allowing the bearing to be fitted into cylindrical housing bores. Design engineers and maintenance personnel prefer to use this design where fixed bearing seats and low-maintenance operation over extended intervals are required.

What protection does the 2RS1 seal offer compared to open bearings?

The factory-fitted 2RS1 seal consists of abiding seals arranged on both sides. This design shields the interior of the bearing from dirt particles and moisture. At the same time, the seal helps to prevent grease from escaping, meaning that relubrication is not required during normal operation. It should be noted, however, that the friction caused by the sliding sealing lips reduces the permissible maximum speed compared with open bearings.
