Linear Bearing Lm40uu Lm50uu for Machine Manufacturing

タイトルまたは説明

High precision open linear bearing LM*0UU LM*0UU for machine 

Product Description
Linear bearings are used with quench linear drive shafts. A system for infinite linear motion. Load ball and quenching drive shaft because it is point contact, allow the load is small, but the linear motion, the friction resistance of the smallest, high precision, fast movement.
Plastic linear bearing bearing with the shaft no special requirements; can withstand greater load than the metal bearings, but because the movement between the bearing and the shaft is sliding friction, so the movement of plastic linear bearing speed is limited; movement resistance than metal straight line Bearings should be large; but its movement noise than metal linear bearings low, especially in the case of high-speed, plastic linear bearing noise with the speed is very small. Plastic linear bearings because of its internal with a chip flute design, it allows the use of large dust in the occasion, the dust during the movement automatically from the chip tank out of the bearing body friction surface; plastic linear bearings also allow the use of the process Cleaning, special materials made of internal sliding film can even be used for long-term operation in liquid.
Classification
(1) Standard type, gap adjustment type linear bearing, open type linear bearing, extended linear bearing, universal linear bearing
(2) flange linear bearings can be divided into: round flange type, flange type, oval flange type, guide round flange type, guide flange type, oriented oval flange type, plus long round flange type.
According to the standard system points:
It is divided into two series, namely LM and LME series, its code LM series for Asia, Southeast Asian countries, Japan, Korea, China and so on. To metric size as the standard, with the linear shaft diameter tolerance is generally h7. LME series for Europe, the United States, Germany, Italy and other regions. To the British size as the standard, there are metric size, with the linear shaft diameter tolerance is generally g6. Two series of structural features, in addition to different sizes, different aperture tolerance, its structure is roughly the same.
By shape:
1: straight type (shaped like a cylinder, usually with a snap spring installation, for the installation of smaller size of the occasion)
2: flange type (the end or the middle of the installation flange, you can use the screw to install, the flange is generally round, square and trimming type three)
3: open type (shape such as straight, the appearance of axial incision, for the need to adjust the gap occasions, sub-large openings and small openings 2)

Usage
Linear bearings are widely used in electronic equipment, food machinery, packaging machinery, medical machinery, printing machinery, textile machinery, machinery, equipment, robots, tool machinery, CNC machine tools, automotive and digital three-dimensional coordinate measuring equipment and other precision equipment Or special machinery industry
