Main features and classifications of cylindrical roller bearings for automobile water pumps

Cylindrical roller bearing rolling element is a radial rolling bearing of cylindrical roller. Cylindrical rollers and raceways are linear contact bearings. Load capacity, mainly bear radial load. The friction between the rolling element and the retaining edge of the ring is small, which is suitable for high-speed rotation. Its main features and classification editors are here to give you a brief introduction

Cylindrical roller bearings can be divided into single-row, double-row and multi-row cylindrical roller bearings according to the number of rows of rolling elements. Bearings with different structures for automobile water pump shaft bearings are also reflected in the design of the rib position. Among them, the commonly used cylindrical roller bearings have the following forms:

Single-row cylindrical roller bearings: Single-row cylindrical roller bearings are separable bearings, which are easy to install and disassemble. Both rings can be tightly fitted. The contact line between the roller and the raceway can be modified to reduce stress concentration. .

Double-row cylindrical roller bearings: Double-row cylindrical roller bearings are floating bearings, and their separability makes it easy to install and disassemble. Both ferrules can be tightly fitted. The double row cylindrical roller bearing almost does not allow inclination angle.
