Four-row tapered roller bearings are the one kind of roll neck bearings, their radial and axial loading capacity are high, can carry heavy axial loads in two directions, and their radial loading capacity is 3 times heavier than singe-row tapered roller bearings, but limiting speed is lower. They can be used as axial locating bearings in two directions because they are able to limit axial displacement in two directions within axial clearance. The radial and axial clearance also can be adjusted by changing the width of spacer between inner and outer rings.

The large rollers applied in the main bearings are supplied by CHG factory

Spherical roller bearings have two rows of rollers and can accept radial loads as well as axial loads in either direction. High radial load capacity, especially suitable for heavy or oscillating load operation. But can not simply bear the axial load. This kind of bearing outer ring raceway is spherical, so its alignment performance is good, can compensate for coaxiality error. But have in the bearing industry ten years of experience in the old workers told us, if the spherical roller bearing heat treatment is not proper is will occur certain impact. But what will happens if the heat treatment

High temperature bearing refers to a kind of high temperature resistant bearings, which can stably guarantee the excellent mechanical performance of the bearing in a high temperature environment for a long time. The working temperature of high temperature bearings is higher than that of ordinary bearings, and the general working temperature is above 150°.

Taper roller Bearings are made to accommodate both radial and axial load, these bearings has good sustainable capacity for both loads in one direction only,if you want to accommodate both the sides of axial load,then we have to make a pair of taper roller bearings with opposite slope assembly.

In the purchase of bearings, sales staff will often ask customers a question: what class of accuracy do you need bearings? This is because different users have different needs for bearings, resulting in different manufacturers provide different bearing precision. But no matter how much more the bearing precision is required, there is still a grade standard for bearing precision. The following is an introduction to some of the precision classes of bearings.
