First, in the case of bad Housing Bearing mounting hole size, shape, accuracy, bearing affected, can not play the best performance. For example, if with the parts within the bearing hole dimensional accuracy and shape accuracy is not good cause deformation of the outer ring of the bearing, resulting in deterioration of the roundness of the bearing; shoulder block accuracy is not good, will produce the outer ring of the bearing, roller tilt, intensified focus load bearing fatigue life decreased more serious cause cage damaged, sintering; If the poor accuracy of the bearing inner the ingot rod bearings file, such as size, roundness, cylindrical, waviness, roughness, the position of the precision of the other aspects will obviously lead to the increase in the value of the entire spindle vibration.
Secondly, complete sets of bearings before assembly undergo a rigorous precision optional, so the user before use, bearing parts scattered without re-measuring matching, can not be used interchangeably.
Third, the spindle bearings and bolster cleaning. Due to bolster compact, the ingot foot cavity in many other parts of cleanliness also affect the cleanliness of the bearing cavity. Therefore, to bolster parts before assembly pre-cleaning, assembly, including the bearing assembly bolster fine cleaning process is more reasonable process.
Fourth, the bearing assembly should not be bump and shock, bump and shock could easily lead to a collision between the bearing parts, resulting in bearing failure.
Fifth, pay attention to controlling the bearing seat curling a good curling angle, intensity and other factors, to avoid curling unreasonable failure caused by the deformation of the bearing parts.
Sixth, for more than rust or stored for longer periods of time bearing may rust or anti-rust oil dried up roller stick dead.
