ZYSL LM12UU linear ball bearing high quality linear ball guide bearing LM12UU

ZYSL LM12UU linear ball bearing high quality linear ball guide bearing LM12UU having small friction coefficient and excellent rotational performance designed for outer ring revolution. LM12UU linear ball bearing works with 12mm Shafts, inner Diameter 12mm, the outer Diameter is 21mm and the Length is 30mm, Bearing has Built-in Rubber SealsWith the purpose of increasing the load area effectively,the radial gap of linear ball bearing LM12UU is smaller than the general linear bearings. Therefore, it alleviates the impact load, and a stable long life is gained. Since the stud undergoes screw processing and stepped processing, they can be attached easily.

LM12UU

1.Systematization of ZYSL LM12UU linear ball bearing:

1). Metal linear ball bearing and Plastic linear ball bearing
2). Standard, Clearance SetUp Coordinate linear bearing, Open mouth linear bearing , The stretched linear bearing , General linear bearing.
3). Flange linear ball bearing can be divided into: round flange type, method, elliptical flange, round flange type, guidance method orchid type, orientation ellipse flange type, extended type circular flange .
4). LM and LME series. Its code LM series used in Asia, southeast Asia, Japan, South Korea, China, etc. Metric size as standard, with the straight axis diameter tolerance is usually h7. LME series is much used in Europe, the United States, Germany, Italy and other regions. Inch size as standard and metric size, with the straight axis diameter tolerance is usually g6. Two big series structure features, in addition to the different size, diameter tolerance is different, its structure is roughly the same.Plastic linear ball bearing can be divided into two major series with LIN -12 and LIN – 11 series, its code name LIN – 11 is the representative of a 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 mounted with its diameter and installing seat hole tight fit.

NMB bearings,BONES REDS bearings…

Non-standard bearings can be produced according to your drawing in our factory.

 

Q: When selecting bearings, what should we need to consider

A: The precision of the bearings (dimension tolerance, loading rate), internal

clearance and hardness under heat treatment, structure of cage and material.

Q:The advantage of bearings
A:

(1) reduce friction and wear.

To prevent metal contact and reduce friction and wear in the contact part of the bearing ring,

rolling body and maintainer.

(2) prolong fatigue life.

The rolling fatigue life of the bearing, in the rotation, the rolling contact surface lubrication good,

then extended. Conversely, the oil viscosity is low, the lubricating film thickness is not good,

then shortened.

(3) exhaust friction heat and cooling.

The circulation to oil method can be used to exhaust the heat generated by friction, or from external

heat, cooling. Prevent the bearing from overheating and prevent the lubricating oil from ageing itself.

Q: Application area of bearings

It can cover almost all mechanical industries, including robotic systems, lathes, tools, automobiles, large equipment, and so on.

Q: Can I have a sample order

A: Yes, we welcome sample order to test and check quality. Mixed samples are acceptable.

Q: What about the lead time

A:Sample needs 3-7 days, mass production time needs 3-4 weeks.

Q:What is your payment method

A: We accept T/T, PAYPAL or Western Union, credit card.
