Product Characteristics

Four-point contact ball bearing is a type of single-row angular contact bearing, and it belongs to separable bearings. The steel balls contact the four points of ferrule, with a contact angle of 35°. The four-point contact ball bearing can be subject to radial load and axial load in any direction or radial and axial combination load. Double-sided axial displacement of shaft or housing is limited in axial windage range of bearing by this type of bearing. Compared with other ball bearings, when axial windages are the same, the axial windage of this type of bearing is smaller, the load capacity is larger, and the limit speed is higher.

This type of bearing is mainly used to be subject to axial load. It is used as thrust bearing with definite axial windage and mounted in bearing box in many occasions. Except normal four-point contact ball bearing, there is also a type of four-point contact ball bearing whose suffix has N2. Two locating slots are positioned on the outer race end of this type of four-point contact ball bearing to facilitate locating and prevent the outer race rotating.

The contact angle of this type of bearing is 40°. The bearing is used to be subject to major radial load, axial load and radial and axial combination load, and is mainly applied on components to limit the double-sided axial displacement of shaft or housing. It is provided with high limit speed.

The original code is 86000. The contact angle of this type of bearing is 45°, and is 26°, 32° and 40° in special circumstances. The bearing is used to be subject to major radial load, axial load and radial and axial combination load, and is mainly applied on components to limit the double-sided axial displacement of shaft or housing. It is provided with high limit speed.

The original code is 56000. The contact angle of this type of bearing is 30°, and is 26° and 35° in special circumstances. The structure is similar to paired angular contact ball bearings matched by two back to back bearings, and the width is less than paired bearings. The bearing can be subject to major radial and axial combination load and axial load in any direction. It can also be subject to major overturning moment. Providing with high limit speed, it is mainly applied on components to limit the double-sided axial displacement of shaft or housing. There is usually a filling slot on one end. The holder is generally brass holder, when the suffix code includes TN, the holder is nylon holder, and there is no filling slot on the ferrule. The bearing can be subject to equal bidirectional axial load.
