In order to ensure the normal operation of FAG imported bearings, there must be a good smooth, rolling bearing rated load and limit speed are in the assumption that the smooth appropriate conditions, the so-called smooth appropriate refers to the choice of appropriate sliding agent, smooth dose is appropriate, poor smooth is often caused by the early destruction of the bearing is one of the main causes.

According to statistics, about 1/3 bearing damage is due to poor smooth. Rolling bearings in the rotation, due to friction resistance to make bearings from time to time wear and failure. Obstacle rolling bearing rotation resistance by rolling friction, sliding friction and smooth agent friction three kinds of composition.

When the rolling body in the bearing raceway rolling rolling friction; adhere to the frame in the rolling body on the guiding surface, adhere to the frame on the guiding surface of the fringe and roller bearings in the roller end face and ring fringe onset of sliding friction; smooth agent friction by the internal friction of the smooth agent in the contact with the mixing and extrusion of the smooth agent is composed of. Therefore, the resistance of impedance bearing movement is the sum of the above three kinds of friction. The purpose of the smooth is through the smooth grease and its smooth way to prevent the raceway, rolling body, adhere to the frame metal direct contact, reduce friction heat 'so that the friction resistance down to small, so as to reduce wear and tear, to avoid corrosion and prolong its service life. As FAG imported bearings through the rust disposal and packaging, so do not open the packaging before the installation.

In addition, bearings coated with antirust oil has good smoothing performance, on the general use of bearings or grease-filled bearings, can be used directly without cleaning. However, for instrument bearings or bearings used for high-speed rotation, clean cleaning oil should be used to wash away the anti-rust oil, when the bearings are prone to rust, and should not be placed for a long time.

Clean the bearings and the shell, make sure there are no scars or burrs left by machining. Absolutely no abrasive (SiC, Al2O3, etc.) sand, chips, etc. in the shell. Secondly, check the shaft and shell size, shape and processing quality can fit with the drawings.
Device FAG imported bearings, due to bearing fit, conditions, construction, ordinary, because more than the shaft rotation, so the inner ring needs interference fit. Cylindrical hole bearings, more presses pressed in, or more hot mounting methods. Tapered hole places, direct device on the taper shaft, or with a sleeve device. Device to the shell, the ordinary clearance fit more, the outer ring overcapacity, usually with a press to press in, or also cooled after the device of the cold shrinkage fit approach. With dry ice as coolant, cold shrinkage with the device place, the moisture in the air will condense in the appearance of the bearing. Therefore, the need for appropriate anti-rust measures. Whether the device FAG import bearings can be correct or not affects the life, accuracy and performance. Therefore, the design and assembly departments should fully discuss the installation of bearings. It is hoped that the installation should be stopped in accordance with the operation specification.
