LM12UU bearing 12x21x30mm LM12UU linear ball bearing
The Brief Introduction of LM12UU bearing 12x21x30mm LM12UU linear ball bearing
LM12UU bearing 12x21x30mm LM12UU linear ball bearing are high precision linear motion rolling guides which travel along shafts to achieve linear motion. In the external cylinder, steel balls are accurately guided by a retainer so that low frictional resistance and stable linear motion can be achieved. For each dimensional series, standard, adjustable clearance and open types are available with and without seals, so the best linear bushing for the application may be selected.
Application of LM12UU bearing 12x21x30mm LM12UU linear ball bearing
LM12UU bearing 12x21x30mm LM12UU linear ball bearing are widely used in electronic equipment, pull tester and the digital three-dimensional coordinate measuring device, such as precision equipment, as well as multi-axis machine tools, press, tool grinder, automatic gas cutting machine, printer, card sorting machine, food packaging machines and other industrial machinery sliding components.

FAQ of LM12UU bearing 12x21x30mm LM12UU linear ball bearing:
Q: What kind of bearings you supplied?
A: We supply all specification of bearings: deep groove ball bearings ----tapered roller bearings----- cylindrical roller bearings ----Spherical Roller Bearings----- angular contact bearings - - thrust roller bearings ----thrust ball bearings----spherical bearings -needle roller bearings----pillow block bearings----sliding guide bearings----wheel hub bearings and high-precision low-noise high-speed operation of special bearings.
Non-standard bearings can be produced according to your drawing in our factory.
A: The precision of the bearings (dimension tolerance, loading rate), internal
clearance and hardness under heat treatment, the structure of cage and material.
Q: The advantage of LM12UU bearing 12x21x30mm LM12UU linear ball bearing?
(1) reduce friction and wear for LM12UU bearing 12x21x30mm LM12UU linear ball bearing
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 of LM12UU bearing 12x21x30mm LM12UU linear ball bearing
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 aging itself.
Q: Application area of LM12UU bearing 12x21x30mm LM12UU linear ball bearing?
It can cover almost all mechanical industries, including robotic systems, lathes, tools, automobiles, large equipment, and so on.
A: Yes, we welcome sample order to test and check quality. Mixed samples are acceptable.
A: Sample needs 3-7 days, mass production time needs 3-4 weeks.
A: We accept T/T, PAYPAL or Western Union, credit card.
