Linear Bearing

Linear Bearing
ISUTAMI linear bearings, also known as linear bushing ball bearings or linear bushing bearing, consist of outer bushings, multiple rows of circulating steel balls, ball retainers and two end buckles (sealing rings), usually used in conjunction with cylindrical shafts for linear motion systems.

The linear bearing bushings are generally made of high-carbon bearing steel or stainless steel and can be rust-proofed on the surface, such as nickel electroplating. The bushing is a main component of the outer structure for the linear bearing. It is characterized by direct contact with the circulating steel ball and the bearing housing, which is an essential element of high load capacity. The bushing achieves a considerable hardness by heat treatment to ensure safety and longevity during exercise, and it is interchangeable.

Linear Bearings Features

The steel ball inside the linear bearing is generally made of high carbon bearing steel or stainless steel material. In addition, ceramic can also be used as the material for balls. Balls can directly contact the linear shaft and the bushing, and supports the load by contact with them,which is an essential element for low friction, high load capacity, high precision and high speed stroke.

The ball retainer is generally made of POM (a kind of resin, engineering plastic), bearing steel or stainless steel, and it is mounted inside the bushing together with the steel ball. Its main feature is to guide the ball movement, which is the basic element of the infinite linear stroke. POM material ball retainers reduce noise and abrasion between the ball and the retainer.

Steel ball and ball retainers are the main components of the internal structure of linear bearings. The retaining ring (seal ring) part is generally made of rubber material such as NBR. It is located at both ends of the linear bearing. Its main function is to fix the ball retainer, block foreign matter and prevent the lubricant from flowing out. The retaining ring (seal ring) is a relatively important component of the external structure for the linear bearing.

As a sliding component, linear bearings are widely used in precision equipment or special machinery industries, such as electronic equipment, food machinery, packaging machinery, medical machinery, printing machinery, textile machinery, robots, CNC machine tools, automobiles and digital three-dimensional coordinate measuring equipment.

At present, ISUTAMI linear bearings can be divided into metric series and imperial (inch) series according to different measurement units. The metric series is divided into Asian series and European series according to different markets. ISUTAMI linear bearings also can be divided into standard type, adjustment type, open type, and long type according to the appearance. In addition, we provide and export super linear bearings, stamping linear bearings KH series, flange linear bearings, etc., covering almost all categories of metal linear bearings, and it is convenient for customer design and use.
