Precision bearings according to ISO grading standards are divided into: P0, P6, P5, P4, P2. Rank higher in turn, where P0 is the general accuracy, other grades are precision level. Of course, different classification standards, different types of bearings, their classification method somewhat different, but the meaning is to the. The use of performance requirements of precision bearings rotating body with high runout accuracy, high-speed rotation and small changes in friction and friction.

FAG 51415-MP bearing types are: Axial deep groove ball bearings, the bearing inner and outer rings more details you can call the Division I, FAG 51415-MP bearing model of the company stock, clearance dimensions, clearance size table , roll Seed number,51415-MP offer price, dimensions, taper bearing drawings, samples, price or replacement products! We are the best agents FAG bearings, the sale of genuine products are original, please rest assured to buy!
FAG Bearings agents to recommend Model: NU321EM bearing 2920 bearing HK0810.2RS bearings 32226-A bearing 6007N bearing 6832 bearings NF238 bearings 2316-M bearing 23152B/23152BK bearing 292/750EM bearings and other bearings.
This bearing can also be used for: cranes, wear testing machine, presses auxiliary, impact testing machine, open chiller, bulldozers, vibration test machine, film blowing machine, condenser, multi-level reducer, and other fields.according to the theory of tribology and virtual testing to establish the bearing life test theoretical mathematical models, computer vibration analysis test preparation software, vibration analysis and testing through computer software, using vibration spectrum resonance demodulation technology, roller bearings for diagnostic testing data .
Bearing testing machine controlled by computer, in a certain condition (load certain) under test Precision bearing when the maximum speed reached 30000r/pm, contact fatigue test bearing the extent of damage. Temperature, vibration, load and other parameters using temperature sensors, pressure sensors, acceleration sensors, the signals to be measured, the computer processing for display, print. The project is based on the indicators proposed bearing technology to achieve the bearing automatically detected. In the performance of detection and analysis device than similar foreign technical indicators must be high, mechanical design more reasonable test load greater test speed higher overall performance automatic control equipment, measurement and advanced technology.
Expert appraisal committee that workers Ming Electrical Equipment Co., Ltd. Luoyang and Xi'an Jiaotong University to complete aircraft engine bearings cyclical dynamic loading test machine project:
1, for large and small aircraft engine test requirements of different spindle bearings were developed bearing diameter of 15-30mm ,30-80mm ,80-180mm three test machines. Testing machine with spindle speed transmission, hydraulic loading serve to achieve a cyclical dynamic precision bearing load, using electromagnetic induction heating can effectively improve the rate of heating oil to meet the requirements of aircraft engine bearing test.
2, developed a vibration spectrum detection device, the preparation of vibration demodulation analysis and control software, failure to establish a bearing life estimation model that can effectively detect bearing failure time.
3, the user indicates that the project test machine stabl
