Characteristics and applications of cylindrical roller bearings

High-precision cylindrical roller bearings with tapered bores are marked with the suffix symbol K and are produced with a taper angle of 1:12. Mainly suitable for the machine tool manufacturing industry, the radial clearance and preload of the tapered hole can be adjusted through the axial movement of the tapered supporting surface of the shaft during assembly.

A brief introduction to tapered roller bearings

Tapered roller bearings mainly bear combined radial and axial loads, which are mainly radial. The load-bearing capacity of the bearing depends on the raceway angle of the outer ring. The larger the angle, the greater the load-bearing capacity. This type of bearing is a separable bearing and is divided into single-row, double-row and four-row tapered roller bearings according to the number of rows of rolling elements in the bearing. The clearance of single-row tapered roller bearings needs to be adjusted by the user during installation; the clearance of double-row and four-row tapered roller bearings has been set according to user requirements before delivery and does not require user adjustment.

Grease lubrication and oil lubrication of bearings

The main purpose of bearing lubrication is to use lubricant to form an isolating lubricating oil film on the friction surfaces between the rings, rolling elements and cages to reduce bearing friction and wear, prevent sintering, and extend the service life of the bearing. In addition, lubricants can also prevent bearing corrosion, reduce vibration and noise, provide cooling, and prevent the intrusion of external foreign matter.

Allowable speed of rolling bearings

The allowable speed of the bearing refers to the allowable speed value at which frictional heating will not cause burns and the bearing can rotate continuously. Therefore, the allowable speed of the bearing depends on various factors such as the type, size and accuracy of the bearing, the lubrication method, the quality and quantity of the lubricant, the material and structure of the cage, and the load conditions (including preload force).

Characteristics and applications of crossed roller bearings

The dimensions of the inner and outer rings of crossed roller bearings are miniaturized, and the ultra-thin type is close to the limit of small size. It has high rigidity and can reach high-precision grades. High-precision bearing products are suitable for joints and rotating parts of industrial robots, rotating tables of machining centers, precision rotating tables, medical equipment, measuring instruments, and IC manufacturing equipment.
