According to the bearing performance characteristics and differences in the application of working conditions, in the selection of a suitable bearing type, bearing the need for routine checks that include bearings, the size and quality of the fitting precision, lubrication, and whether parts the existence of signs of wear, and so on. Of course, bearing inspection has been completed, should be carried out the following tasks: First, wash the bearings, the point to note is that there is a sealing device F & Z bearings can omit this part clean, because cleaning inside the bearing will cause foreign body intrusion, affect the normal use of the bearing; Second, one must keep dry bearings, bearing on the need for cleaning, rust when washed bearings, bearings must be dry, otherwise easily lead to rust bearings; Third, to maintain lubrication of smoothness.
In addition to pre-installation checks bearing, but also to deal with the bearing radial clearance testing. Including bearing radial clearance in the natural state of the original clearance, after bearing installation caused the original clearance changes with clearance, clearance under actual working temperature and load role in the formation. Due to the size of radial clearance directly affects the F & Z bearing operating temperature, vibration and duration values of life, etc., so the detection of F & Z bearing radial clearance is particularly important. For different bearing, how it is measured radial clearance it?
1, the radial clearance measurements require the use of special instruments to measure tools as possible when there is no special equipment on hand, you can use a tool such as a feeler gauge to measure. When using a feeler, it should be noted that the roller can not be measured using methods from the past feeler on rolling. When using the manual measurement method, this method of measurement were higher, and is an easy method for generating an error, it is generally not recommended.
2, for the F & Z in terms of multi-row bearings, each column of its clearance requirements are high, must all be qualified.
3, the measurement process, should ensure that the roller bearings are falling into the ditch.
