Linear Motion Bearing LM20UU Bearing LM20UU-OP

classification

(1) standard, gather linear bearing clearance, open rack linear bearings, linear bearings, linear bearing commonality lengthened

(2) the flange linear bearing can be divided into: round flange type, method type, elliptical flange type, guided round flange, guiding method, guide the elliptical flange type, extended round flange type.

According to the specification standard points:

Divided into two series of LM and LME series. Its code LM series used in Asia, southeast Asia, Japan, South Korea, China, etc.

On the basis of metric size, with straight axis diameter tolerance is usually h7.

LME series used in Europe, the United States, Germany, Italy and other regions.

On the basis of inch size. Also have metric size, with the straight axis diameter tolerance is usually g6.

Two big series structure characteristics, in addition to different sizes, different pore size tolerance, its structure is roughly the same.

Case 1: LM 203242 UU OP

The first set of standard LM said straight line

203242 said size structure of aperture diameter length

UU said double seal structure OP said open rack

Example 2: the LME 203245 UU AJ

The LME said linear second series standard

203245 said size structure of aperture diameter length

UU said double seal structure AJ said clearance is adjustable

Plastic linear bearing can be divided into two major series with LIN LIN - 11-12 series, the code LIN - 11 represents the European standard plastic linear bearing, and LIN - 12 series is narrow type design, mainly in order to save installation space and design;

Distinguishes between two major series, LIN - 11 series is using circlip limit installation, and LIN - 12 series is directly adopted its installed outside diameter and hole a tight fit.

LIN - 11 European standard plastic linear bearing

LIN - 11 European standard plastic linear bearing

Example 3: LIN - 11 r - 30

LIN - 11 on behalf of the European standard size series plastic linear bearing

R is for belt retainer outside

30 representative bearing inner hole diameter of 30 mm

Example 4: LIN - 12-30 r

LIN - 12 representative narrow design dimension series of plastic linear bearing

R is for belt retainer outside

30 representative bearing inner hole diameter of 30 mm

LIN - 12 narrow plastic linear bearing design

 LIN - 12 narrow plastic linear bearing design

According to the shape of points:

Type 1: straight (shapes such as cylinders, spring is commonly used in installation, for special occasions requiring small installation size)

Type 2: flange (end or intermediate flange, with installation can use screw to install, general component is circular flange, square and trimming type three)

3: open your mouth (shape, such as straight, appearance has axial slitting, used to need clearance adjustment, large openings and small openings)

According to the performance points:

1: normal (generally use of performance requirements)

Type 2: super (long life and large load performance requirements)

Application

Linear bearing is more and more widely applied to electronic equipment, food machinery, packaging machinery, medical machinery, printing machinery, textile machinery, machinery, instrument, robots, machine tools, CNC machine tools, automobile and digital 3 d coordinate measuring equipment such as precision equipment or special machinery industry.
