Structure and Features

Linear Bushing model LM is a linear motion system used in combination with a cylindrical LM shaft to perform infinite straight motion. The balls in the loaded area of the nut are in point contact with the LM shaft. This allows straight motion with minimal friction resistance and achieves highly accurate and smooth motion despite the small permissible load.

Application

The nut uses high-carbon chromium bearing steel and its outer and inner surfaces are ground after being heat-treated.

The Linear Bushing is used in a broad array of applications, such as slide units of precision equip-ment including OA equipment and peripherals, measuring instruments, automatic recorders and dig-ital 3D measuring instruments, industrial machines including multi-spindle drilling machine, punching press, tool grinder, automatic gas cutting apparatus, printing machine, card selector and food pack-ing machine.

Interchangeability

Since the dimensional tolerances of the Linear Bush's components are standardized, they are in changeable. The LM shaft is machined through cylindrical grinding, which can easily be performed, and it allows highly accurate fitting clearance to be achieved.

Highly Accurate Retainer Plate

Since the retainer, which guides three to eight rows of balls, is integrally molded, it is capable of ac-curately guiding the balls in the traveling direction and achieving stable running accuracy.Small-diameter types use integrally molded retainers made of synthetic resin. It reduces noise gen-erated during operation and allows for superb lubrication.

Wide Array of Types

A wide array of types are available, such as standard type, clearance-adjustable type, open type, long type and flanged linear bushing,allowing the user to select a type that meets the intended use.

FAQ

1. Why do the bearings I receive have shaking?

The clearance of the bearing is related to the play.The default is the standard C0 clearance, which is usually 3-18um.The corresponding principle is shown in the figure below.If you don't need to shake, please choose C2 small clearance bearing,If you have any questions, please contact us before purchasing.

2. What is the accuracy of ABEC-1?

ABEC is the American ANSI standard.The corresponding German DIN standard and international ISO standard are as follows:
