Buy TIMKEN bearing size should pay attention to those matters'


Kunshan Bearings, TIMKEN bearings TIMKEN bearing size price consulting measurement points to note: 1.TIMKEN bearing thickness: TIMKEN bearings should be noted when measuring trace amounts in recent openings thinning. TIMKEN Bearing thickness measurement should be fixed outside diameter micrometer size spherical probe by a plane instead.
      2 TIMKEN Backing bearings measurement to control the thickness of 0.00 5 to 0.0 within ten millimeters, or make TIMKEN bearing diameter deviation.
      3.TIMKEN bearing diameter: TIMKEN bearing shaft diameter corresponding to the diameter size Energizer difference is with the gap. TIMKEN bearings before the measurement needs to be tightened to the specified torque order cap bolts, and then use the inner scale required before measuring micrometer in diameter on the basis of size proofreading, and the measurement at the same time should avoid thinning area.
      4 Main TIMKEN bearing bore concentricity: Order of the hole concentricity error is the main TIMKEN bearing bore concentricity error of the main reason for the cause deformation of the cylinder bore axis is the order of the degree of error.bearing large quantities of goods and sometimes, not one hundred percent inspection, then it should be what kind of sampling plan, what quantity taken for examination in order to more fully with sufficient reliability to represent the quality of all merchandise timken bearing, and test results and according to what criteria to be measured to determine whether these products are qualified batch should be accepted or rejected should be unqualified approval.
I will introduce the bearing load calculation. One-way bearing size selection, we recommend that customers follow Bearing static load and dynamic load-independent checks accurate formula. Static load includes two, one is the loading effect at low speeds, is a high-speed, heavy duty, static load factor of bearings. Should be selected dynamically load inspection, the specific conditions of load spectrum. Select bearing systematic approach and bearing reliability.
