6311 2rs Deep groove ball bearing

Deep groove ball bearings have a wide range of applications. They are suitable for high speed and ultra high speed, they can adapt to radial and axial loads in two directions, and require almost no maintenance. Deep groove ball bearings are widely used bearing types. Bearings are available in deep groove ball bearings in a variety of designs, variants and sizes.

There are two types of deep groove ball bearings: single-row and double-row. The deep groove ball structure is also divided into sealed and open structures. The open type refers to the bearing without a sealed structure. The sealed deep groove ball is divided into dust-proof seal and oil-proof. seal. The dust seal cover material is stamped from a steel plate, which simply prevents dust from entering the bearing raceway. The oil-proof type is a contact oil seal, which can effectively prevent the grease in the bearing from overflowing.

Deep groove ball bearings mainly bear radial load, and can also bear radial load and axial load at the same time. When it is only subjected to radial loads, the contact angle is zero. When a deep groove ball bearing has a large radial clearance, it has the performance of an angular contact bearing and can withstand a large axial load. The deep groove ball bearing has a small friction coefficient and a high limit speed.
