We are specialized in the design, research and production to various non standard bearing, imported substitution bearing and special bearing, which are widely applied to aerospace, precision instruments, textile, precision lathe, port, mining, medical treatment, coal, cement, oil drilling, wind power generation, industrial robots, defense industry and other fields. A large number of our products are exported to the United States, Britain, Canada, Germany, Austria, Italy, Japan, Korea, Singapore, India, Pakistan, Thailand, Malaysia and other countries. We have got ISO9001: 2000 certificate, as it is represented in "Quality Guideline", Lirui bearing focus on comprehensive quality management, and take it as a sustained effort to improve customer satisfaction.
Precious cross roller bearing is mainly applied to joint and rotating parts of industrial robot, rotary worktable of machinery processing center, mechanical rotary parts, precious rotary worktable, medical instruments, measuring instruments, IC manufacturing equipment, microscope, welding stents, rotary surface grinding machines, and vertical grinding machines, etc.
Crossed cylindrical roller bearing has multiple structures along with retainer, isolation block and full roller, which has completely rich and various series. Structures with retainer and separator are suitable for parts with low friction coefficient and high speed, while full roller type is suitable for parts with low speed and heavy load. Cross cylindrical sealed roller bearing has sealed rings with special synthetic rubber on the side of the bearing, which makes it very effective for dust-proof and grease leakage
We now produce substitute imported cross roller bearings, like: IKO bearing, CRBF, CRBH, CRB, CRBC, CRBS series, THK bearing RU, RB, RE, RA, the RA-C series cross roller bearing. Structures such as the attached mounting holes, with retainer, with isolation block, full roller and double sealed type are all available.
Cylindrical roller bearing.
Cylindrical roller and its race is line contact, with great radial load capacity, that is applicable to bear heavy load and shock load, also applies to high speed rotation and axial movement, N and NU type can be able to adapt to the change of relative position between shaft and shell, caused by thermal expansion or installation error, most suitable as the free end bearing. NJ and NF type can withstand a certain degree of one-way axial load, NH and NUP type can withstand two-way axial load inner ring and outer ring separable in a certain degree, which is completely convenient handling, Due to the strong rigidity of resistance radial load, making NNU and NN type mostly used for machine tool spindle.
Main use: Medium and large motors, generators, internal combustion engines, gas turbine, machine tool spindle, speed reducer, loading and unloading handling machinery, all kinds of industrial machinery
Note: Four-row cylindrical roller bearings can withstand the big radial direction load, cannot limit the axial displacement, often used for rolling mill and other heavy machinery.
