China bearing factory 55x120x29mm for stenter machine 21311
These bearings have two rows of barrel shaped (spherical) rollers which run on a common spherical outer and inner raceway, they are inclined at an angle to the bearings axis. Their design offers many features such as self alignment, insensitivity to misalignment, tolerance to heavy radial and axial loads etc. They are manufactured with in both parallel and tapered bore variants.
Benefits: High radial and axial loads, misalignment, taper and parallel bore options.
Description of spherical roller bearings (20000CC type)
Machine is running, the installation single bearings parts to allow a certain degree of temperature, when hands body shell, should not feel hot as normal, which in turn indicates that the bearing temperature is too high.
Bearing high temperature causes are: lubricants quality does not meet the requirements, or degenerate, lubricant viscosity too high body assembled too tight (insufficient gap); import bearing too tight; bearing washer on the shaft or housing rotation; load too large; bearing cage or rolling fragmentation.
Allowed light work in the work of rolling bearing noise if noise is too large or unusual noise or bump, then bearing failure.
bearing noise is caused is more complex, and one is the inner and outer rings of bearing surface wear. Because this kind of wear and tear, damage bearings, bearings and shaft with shell combined with led axis deviation from the correct location, in abnormal sound when axis at high speed. When one-way bearing fatigue is, its surface metal Flake also makes bearing radial clearance increases noise. In addition, the bearing lubrication insufficient formation of dry friction, as well as the bearing crush produces abnormal noises. After bearing wear loose, loose cage damage, will also have an abnormal noise bearing failures.
Bearing removal check when judging according to bearing damage bearing failures and the cause of the damage.
