TIMKEN bearing failure are common bearing problems. TIMKEN bearing failure was caused by reasons generally divided into two kinds, one is the normal failure failure of a non-normal. Normal failure description General bearing service life is achieved. To say today is a non-normal failure. This situation typically bearing accidental damage may occur.
　　TIMKEN bearing this situation, we provides an analysis of non-normal failure, general cause of bearing damage is as follows:
　　1, TIMKEN bearing axis skewed (wrong) abutment on the mating surfaces of the shaft and the case is not vertical, shell when installing two or more bearing bore a different axis.
　　2, poor axis of rigid, bent occurs under load is too large, bearing two fixed end-span large temperature rise caused by thermal elongation of shaft axis of bending of statically indeterminate nature.
　　3, poor bearing manufacturing precision, fit the end bearing and more You Yuan is large, poor bearing rigidity. Or end of housing inequality.
　　4, assembling hands of hard particles or dirt, the surface opposite to the stress concentration of Plummer block bearing ring when the clamp clip flat.
　　5, improper rebar uranium bearing shaft tolerance of inequality, housing or have hole of pressure on local strength fasteners, such as screws, brace with grooves or printed close to the bearing Raceway.
　　TIMKEN bearings bearings are bearings is excellent, right now we have to say is in the middle of using, must be careful. Not to create unusual failure of TIMKEN bearings.
