● Introduction

LM linear bearings consist of an outer cylinder, steel ball, retainer and retaining rings at both ends. The retainer is fixed by buckles at both ends, so that the steel balls can be repeatedly circulated on the track surface without falling off. Notched windows are arranged in the direction of the linear track where each steel ball is under force. This part is the rolling contact between the loaded steel ball and the shaft, which can move relatively with a very low coefficient of friction. Linear ball bearing is a linear motion system. The bearing is used in conjunction with the shaft, and the shaft must be processed by heat treatment and grinding. The bearing friction is small, which can realize smooth linear motion with high sensitivity and precision. Due to the point contact between the bearing ball and the bearing shell, the load of LM linear bearings is small, the bearing capacity is poor, and the impact load capacity is also poor.

Linear bearings are widely used in mechanical equipment, automation equipment, electronic equipment, food machinery, packaging machinery, medical machinery, printing machinery, textile machinery, instruments, vehicles and other fields.

● Bearing Series

The types of the bearings include LM..UU series, LM..LUU series, LME..UU series and LME..LUU series.

● Production Details

◆ Guarantee of machining accuracy of bearing rings

Although for turning, the main surfaces (working and positioning surfaces) of the ferrule are not final machining, but without good machining accuracy as a basis, it is not feasible or economical to rely only on subsequent operations. For example, large shape and position errors and large allowances in front machining will increase the workload of grinding, affect the quality of grinding, and even fail to meet the final requirements of the parts, resulting in waste. The problem of ensuring and improving turning machining accuracy is to limit and reduce machining errors.

◆ Cutting amount for bearing ring turning

The Cutting amount of bearing ring turning is related to the cutting speed V, the feed amount f (or the feed speed V) and the depth of cut. The cutting amount directly affects the productivity and processing quality. The factors that generally affect the cutting amount are as follows: the physical properties, cutting performance and mechanical properties of the bearing ring material. The physical and mechanical properties of the tool material and the geometric parameters of the tool.

The type, intrinsic quality, size, shape, manufacturing accuracy and surface quality of the blank or semi-finished product. The structure and performance of the lathe and fixture, the rigidity and thermal deformation of the process system. The processing method and steps of the ferrule, and the processing quality of the ferrule after cutting requirements. Others such as the cooling method of the processing part, the technical level of the workers, etc.

● Selection of Steel Ball

The single particle vibration value of the steel ball is the main cause of the bearing vibration. Practice has proved that in terms of ferrules, steel balls and cages, the most important factor affecting vibration is the single-particle vibration value of the steel ball (determined by the geometric accuracy of the steel ball). The principle is: during the rotation of the bearing, the spin frequency of the steel ball is the highest. The working surface of the steel ball is in contact with the inner and outer channels at the same time. The second is the geometric accuracy of the inner ring channel surface, the third is the outer ring channel surface geometric accuracy.
