Introduction

Four-point contact ball bearings are radial single row angular contact ball bearings with raceways that are designed to support axial loads in both directions. For a given axial load, a limited radial load can also be supported. The bearings are separable, i.e. the outer ring with ball and cage assembly can be mounted separately from the two inner ring halves.

Both inner ring halves of Explorer four-point contact ball bearings have a recessed shoulder. This improves oil flow when the bearing is used in combination with an cylindrical roller bearing. In addition, these recesses can be used to facilitate dismounting.

Features and Benefits

• ●Accommodates axial loads in both directions
• ●Less axial space
  These bearings take up considerably less axial space than double row bearings.
• ●High load carrying capacity
  A large number of balls are incorporated, giving the bearing its high load carrying capacity.
• ●Separable design
  The split inner ring leads to easier mounting and dismounting of the bearing.
• ●Improved oil flo
• Limited inner ring deformation when subjected to high clamping forces.

Function

When only pure axial loads are applied, the ball and ring form a two-point contact capable of bearing bidirectional axial loads. Four point contact ball bearings are ok.

Bearing torque load, it has the functions of single row angular contact ball bearing and double row angular contact ball bearing. The four-point contact ball bearing can work normally only when the two point contact is formed. Therefore, it is generally suitable for those pure axial load or large axial load under the composite load of two-point contact, four-point contact ball bearing limit speed is high, but also suitable for those high-speed operation occasions.

Characteristics

The four-point contact ball bearing is a separable structure, and a single bearing can replace the angular contact ball bearing with the front combination or the back combination.

It can bear radial load and bidirectional axial load, and can limit the axial displacement in two directions, but it occupies less axial space than the current specification double row angular contact ball bearing.

Compared with other ball bearings, four-point contact ball bearings have smaller axial clearance and higher limit speed when the radial clearance is the same.

Four-point contact ball bearings are suitable for bearing pure axial loads or combined axial and radial loads based on axial loads. Due to the double-half inner ring (or outer ring), the number of balls is increased and the bearing capacity is larger.

Under normal working conditions, this type of bearing can form a contact angle when bearing axial load in any direction, and the steel ball is in contact with the inner and outer raceways at one point to avoid large sliding friction in the contact area. Therefore, the bearing should not be subjected to radial forces and loads.
