Bearing installation should be preceded with petrol or kerosene to clean, dry after use, and ensure good lubrication, double deep groove ball bearing the general use of bearing designation OF 6313 BEARING grease lubrication, oil lubrication can be applied. With grease lubrication, should be used without impurities, oxidation, rust, extreme pressure and the superior performance of lubricating grease. Amount of bearing designation OF 6313 BEARING grease filled bearings and bearing box volume of 30%-60%, not too much. With grease has been filled with good seal and double deep groove ball bearing structure, users can directly use, no further cleaning.
Bearing installation, bearing must be applied equally in the circumference of ferrule end face pressure, will press into the ring, not directly strike the bearing end face want first tool, so as not to damage the bearing. Small amount of interference in the case, can suppress at room temperature with the sleeve bearing ring face, beating with a hammer sleeve, through the sleeve will be pressed into the ring balance. If the high-volume installation, use of hydraulic machine.

Indentation, should ensure the outer end face and shoulder shell surface, the inner end face and shoulder axis end pressing, do not allow a gap.
(1) the measuring shaft and bearing seat hole size, to determine with precision bearings, with the inner ring and shaft requirements are as follows: the fit, the amount of interference of 0 ~ +4 μ m (at light load, high accuracy is 0); outer ring and bearing seat hole to take the clearance, clearance of bearing designation OF 6313 BEARING 0 to +6 μ m (but bearing in the free end of the contact angle of angular contact ball bearing, can also increase the gap); shaft and hole surface roundness error below 2 m, face and double deep groove ball bearings with spacer parallel degree below 2 m, the inner surface of the end face of the shaft shoulder external beating 2 μ m; bearing seat hole shoulder axis of bearing designation OF 6313 BEARING the beating of under 4 μ m; spindle front cover end face runout of the axis under 4
(2) fixed end bearing on the shaft: double row deep groove ball bearing cleaning with kerosene to clean a thorough cleaning, for grease lubrication, the organic solvent containing 3% ~ 5% of grease into the bearing cleaning, reoccupy gun will grease filled bearing (for bearing space volume 10% ~ 15%); heating temperature 20 ～ 30 ℃ bearing, oil press used the bearing into the shaft end; the locking sleeve on the shaft and to the appropriate pressure against the end face of bearing designation OF 6313 BEARING the bearing so that the axial location; the spring balance tape on the outer ring of the bearing, pre load imposed by checking method starting torque measurement is greatly change (even double deep groove ball bearing is very correct, but the fit or cage deformation, pre load also could change).
