Correct maintenance bearing considering problems

Under normal circumstances, to determine whether removed bearing normal use, check after wash bearing. Check the raceway surface, rolling surface, cooperate with the state, the abrasion of cage, the increase of the bearing clearance and has nothing to do with dimension precision falling damage, abnormal. Non separation of small ball bearings, with one hand will support level, the inner ring spinning confirm whether smooth outer ring. Separation of tapered roller bearings and bearing, rolling body, the outer ring raceway surface can be respectively. Large bearing can't rotate with the hand, pay attention to check the rolling element and raceway surface, cage, guard surface appearance, such as the importance of bearing high must check carefully. You need the bearings after rinsing with cloth will wipe dry, add the anti-rust oil soaked. In this process, will fully contact with the anti-rust oil bearing, don't stop rotating bearing, so that the rust-proof oil forming oil film covering on the surface of bearing, which can achieve the purpose of rust. You then need to use butter evenly coated on the surface of bearing, including inside and outside the circle, wheels, cage. And wipe while rotating bearing, makes the butter into the real bearing internal, sufficient lubrication effect. Using bearing should be paid attention to the following: 1, keep the bearing and the surrounding environment clean dust into the bearing even invisible to the naked eye smile, also can increase the bearing wear, vibration and noise. 2, use the installation should be careful when not allowed powerful punch, are not allowed to use hammer percussion bearing directly, not allowed by transfer roller pressure. 3, the use of appropriate and accurate installation tools use a special tool, as far as possible to avoid use cloth class and short fiber, things like that. 4, to prevent rusting of the bearings directly with the hand take bearing, to fully wash hands sweat, and again after coated with high quality mineral oils, especially in the rainy season and summer to pay attention to rust.
