Introduction

It is a kind of bearing unit that combines rolling bearing and bearing pedestal. Most of the outer spherical bearings are made into a sphere with the outer diameter and installed together with the imported bearing seat with a spherical inner hole.

They have various structural forms, good versatility and interchangeability. At the same time, this kind of bearing is designed to be self-regulating, easy to install, with a dual structure of sealing device, can work in harsh environment. 

The characteristics of Excellent sealing performance

Both sides of the outer spherical ball bearing are equipped with heat and oil proof rubber sealing ring and steel dust cover combined seal.

Dust cover assembly on the bearing inner ring diameter, together with the inner ring rotation, can effectively prevent the internal external foreign body into the bearing, and can resist the external pressure to protect bearings, the combination of this consists of sealing ring and dust cover seal to prevent dirt, dust and water enter the bearing internal, also can prevent the grease inside the bearing.The bearing can maintain perfect performance even in harsh working environment.

Installation is simple

The outer spherical ball bearing has been pre-filled with enough high quality grease, the outer spherical ball bearing with seat can be installed directly on the shaft. Thus, harmful substances can be avoided in the process of mounting the bearing unit.

Advantages and disadvantages

1) attrition and wear in the bearing of the ring, the skeleton body and the support of the mutual contact part, to avoid metal contact, attrition and wear.

2) prolong the fatigue life of the fatigue life of the bearing body, in the rotation, the bone contact surface lubricating oil is satisfactory, then extend. On the contrary, the oil viscosity is low, the lubricating oil film thickness is very bad, then reduced.

3) Eliminate friction heat, cooling cycle to feed oil and other methods can exhaust the calories generated by friction, or heat from the outside, to play a cooling effect. Avoid bearing overheating and lubricating oil aging.

4) Others also have the effect of avoiding foreign matter entering the inside of the domestic bearing, or avoiding rust and corrosion.

Applicable

Machinery with small installation space, roller conveyor, etc.
