Support bearing should check before installation requirements

1, sharply should have no slag inclusion defects such as cracks, pores, pits, or fall off. 2, bearing the horizontal joint surface must be good contact, with 0. 05 mm feeler check shall not be into. Between the bushing and bearing shell must connect closely. Bearing shell of the sphere with depression nest between faying surface must be smooth, contact surface should be above 70% and uniform distribution, under special circumstances, when the equipment is flawed, close to the horizontal joint surface parts have a little poor contact case, but 0. 05 mm feeler into length should not exceed 10% of the radius of the sphere. Good in upper and lower half bearing combination, upper and lower half bearing shell of spherical and upper and lower half a hollow nest hi-lo is not permitted. 3, bearing oil hole should be clean. Oil hole should be consistent with the direction of the bearing to oil hole and are against one another. Oil hole through each joint surface with color inspection, the sides of the oil hole must be well connected. 4, lower bearing pillow block in contact with the bearing shell should be close-grained, carrying surface should be above 60%. 5, with oil hole on the throttling of the bearing should be measuring the diameter of the orifice, and make a record. The throttling orifice plate shall not interfere with tile pillow block contact with the bearing shell. 6, bearing components shall be steel size, to ensure the correctness of the location and direction.
