Anti-Friction bearing/Strut bearing/Shock absorber bearing(200 pieces per piece)

The pressure bearing can rotate flexibly under an axial pressure of 5,000N, and the rotation side shall be added with special lubricating grease; Apply an axial pressure of 5,000N on the bearing, turn left and right 45 °, and speed at 0.5HZ, the starting torque is less than 3.5N ` m, and rotating torque is less than 3.0N ` m; There shall be no damage, abnormal sound or clamping stagnation when an axial pressure of 12,000N on the bearing is applied, and be turned left and right 45 ° and rotated 500,000 times, turn left and right 45 °, speed at 1HZ and rotate for 1,000,000 times to test the method and item 2; the starting torque is less than 4N`m and and rotating torque is less than 3.5N`m;.syi
