What are the classifications of tapered roller bearings?

Single row tapered roller bearings have an outer ring, an inner ring and a set of tapered rollers, which are composed of an inner ring assembly composed of a basket-shaped cage. The outer ring can be separated from the inner ring assembly. According to the ISO tapered roller bearing external dimension standard, any standard type of tapered roller bearing outer ring or inner ring assembly should be able to achieve international compatibility with the same type of outer ring or inner ring assembly. exchange.

Precautions for bearing storage

In contact with corrosive chemical media, the bearing is not cleaned cleanly, there is dirt on the surface, or the bearing is touched with sweaty hands. After the bearing is cleaned, it is not packaged or installed in time, and it is exposed to the air for a long time, and is attacked by air moisture and contamination; contamination

Installation method of deep groove ball bearings

Deep groove ball bearing installation method 1: Press fit: When the inner ring of the bearing is tightly matched with the shaft, and the outer ring is loosely matched with the bearing seat hole, a press can be used to press the bearing onto the shaft first, and then install the shaft together with the bearing. Put them into the bearing seat hole together. When pressing, place an assembly sleeve made of soft metal material (copper or mild steel) on the end face of the inner ring of the bearing.

Bearing characteristics of deep groove ball bearings

Deep groove ball bearings are the most commonly used rolling bearings. Its structure is simple and easy to use. It is mainly used to bear radial load, but when the radial clearance of the bearing is increased, it has a certain performance of angular contact ball bearing, and can bear combined radial and axial loads. When the rotation speed is high and it is not suitable to use thrust ball bearings, it can also be used to bear pure axial load. Compared with other types of bearings with the same specifications and dimensions as deep groove ball bearings, this type of bearing has a small friction coefficient and a high limit speed. But it is not impact resistant and not suitable for bearing heavy loads.

Physical properties of high temperature resistant materials for bearings

Porosity: refers to the percentage of pore volume in the material as a percentage of the total volume of the material. The pores of SKF bearing high temperature resistant materials can be divided into three types according to their existing forms: closed pores, one pores - pores connected to the outside atmosphere, connected pores - the proportion of the entire pores is 7L. Small SKF bearing high temperature resistant materials have the ability to resist erosion and structural strength; the higher the porosity, especially the more interconnected pores, the lower the thermal conductivity of the material. Lightweight adobe bricks, lightweight high-alumina bricks and other insulation materials use a method to increase porosity and reduce their thermal conductivity.
