铁姆肯公司( Iron, Ken) Imperial tapered roller bearing accuracy tolerance grade standard

铁姆肯公司( Iron, Ken) Imperial tapered roller bearing accuracy tolerance grade standard 2019 - 10 - 11,铁姆肯公司( Iron, Ken) The company is a leading global imperial tapered roller bearings manufacturers. Imperial tapered roller bearing is refers to the unit of measure for the overall dimensions are calculated by inch tapered roller bearings. Tolerance grade of imperial tapered roller bearing is self-contained, and metric system tapered roller bearing of tolerance are not the same, such as the inner and outer diameter of the imperial tapered roller bearings are all positive, and the metric of the inner and outer diameter of the tapered roller bearing tolerance is negative, and so on. 铁姆肯公司( Iron, Ken) Imperial tapered roller bearings tolerance grade is divided into 4, 2, 3, 0, 00, precision from low to high at a time. With the TIMKEN ( Iron, Ken) The metric system and ISO/DIN standard tolerance grade control in the following table. 2, inch tapered roller bearing can be made according to the tolerance grade level 6, but the level 4 and 2 is a common, usually referred to as' standard 'level. Level 2 is more sophisticated than level 4 control some tolerance, so it is possible that in certain applications need more. 3, 0, 00, 000 is a precision level. 2. Two inner diameter tolerance. The outside diameter tolerance of 2. 3 with flange diameter tolerance 2. 4 inner ring width tolerance of 2. Outer ring width tolerance May 2. 6 inner ring high a high tolerance of inner ring is the measurement of inner ring raceway size, taper and the diameter of the roller change. Specific criteria by outer ring or other type of measuring tool reference plane relative to the reference circle the axial location to test. 2. 7 a high outer tolerance of outer ring is high external circle diameter, size and taper is measured. By measuring standard inner ring or other types of measuring tool reference plane relative to the outer ring reference plane to measure the axial position. 2. 8 total width tolerance of 2. 9 largest radial runout hk united bearing focus bearing industry informationization service nearly 20 years, with many excellent bearing enterprise grows together, also witnessed China's bearing production technology from low to high development process. We will adhere to continue, the steadfast work, don't, don't give up, for the benign development of Chinese bearing industry do render some. Hk united bearing network bearing engineers, 2019. 04. 11
