Deep Groove Ball Bearing
Deep groove Ball Bearings are with the characteristics of simply designed structures; low friction coefficient and high limit rotational speed. Their range of application is very wide. Applications of this type of Bearing can be found in situations where there are no special requirements for mounting and sealing.They can mainly carry radial load and certain thrust load. When the radial internal clearance increased, the bearings have the functions of angular contact ball bearings that a larger thrust load can also be carried.
The shields are made of steel sheet. Adequate lubricating grease has been put in the deep groove ball bearings with two shields during assembling process and there is no need to clean the bearing or add lubricant as mounting. It is noncontact seal, and compared with deep groove ball bearings with seals, they have less friction and suitable for applications with high rotational speed requirement.
The seals are made of rubber with steel sheet reinforcement. It is contact sealing that could seal much better but have high friction and low limit rotation speed if the seals contact with the outside of the inner ring; while it is non-contact sealing that has the same limit rotation speed as the basic type. The lubricant has been prefilled in the bearing with seals both sides, so there is no need to clean and fill the lubricant as mounting.
