A lot of people want to learn something about INA bearing of technical knowledge, after all, now China's installation of the mechanical equipment is INA bearing very much, in the machinery industry mix of people learn some INA bearing technology knowledge is very necessary. Below we introduce INA bearing of knowledge.
INA caused bearing heating cause
INA bearing installed skewed, can cause the ball is not bearing groove in the correct position rolling, and even cause larger ball end face and a circle in the bearing INA outside block and block a circle of axial force, causing bearing overheating.
Sometimes trunnion and housings hole because size measurement are not accurate or cooperate with surface roughness is not up to standard, cause too much interference cooperate, make the bearing circle is much extrusion, leading to the INA bearing itself radial clearance of reducing, make INA bearing drive difficult, fever, wear aggravate or card to die, will cause serious bearing a lap when installing the inside and outside.
INA bearing maintenance
All the INA bearing of friction bearings basically contain two hardened steel ring, more hardened the ball or roller, and a separate roller or roller separation frame or keep frame. These types in use and is divided into many kinds. Some types, such as needle column bearing, may not have the inner loop, roller directly in the hardened axis movement.
INA bearing lubrication
In practice is necessary to use more than recommended amount of grease is some. When required torsion low, only need very little can be done on the bearing grease lubrication. When speed is low and INA bearing exposure in the dust, or when wet, bearing may almost will be filled. Bearing in high speed and high temperature condition than usually need usually more frequent lubrication.
