In addition, the bearing coating anti rust oil with good lubricity, for general purpose EDA bearings bearings or filling grease, can not directly use cleaning. But for the instrument bearing or bearing for high-speed rotation, cleaning oil with clean antirust oil wash, the bearing is easy to rust, not long time placed.
Test 2, shaft and housing
Clean the bearing and shell, no burr scars or machining left. Secondly, inspection shaft and the casing size, shape and machining quality and drawings in accordance with.

Method of installing EDA bearings, bearing, conditions, with structure and, in general, due to rotate, so the inner ring interference fit is required.
Bearings with a cylindrical bore, multi-purpose press press, or use the hot charging method. Tapered bore, directly installed in the taper shaft, or sleeve installation. Tapered bore, directly installed in the taper shaft, or sleeve installation.
Mounted to the housing, general clearance, there is interference in the outer ring, usually with presses into, or have shrink fit method of installing cooling. Using dry ice as a cooling agent, shrink fit occasion, the moisture in the air condenses on the bearing surface. So, need appropriate antirust measures.
Can be used to judge, is considered during the EDA bearing damage, mechanical properties, the importance, operating conditions, until the next maintenance decision. However, if the following defects can not use, the replacement of the new EDA deep groove ball bearing must be:
(a) the inner ring, outer ring, rolling body, cage there any cracks or gaps;
(b) ring, rolling body fault on any one;
(c) the raceway surface, rolling rib, a marked card injuries on the body;
(d) the retainer wear significantly, or rivet significant relaxation;
(E) the raceway surface, rolling body rust, injury;
(f) the raceway surface, rolling there is serious indentation and trace;
(g) the diameter of the inner ring or outer diameter surface creep significantly;
(H) discoloration caused by the heat of the obvious;
(I) EDA grease sealed bearings, seals or shields damaged obviously.
