NSK bearings, deep groove ball bearing positioning

Approximate whistling sound, mixed with the rolling noise of rolling element bearing lack of grease or improper selection of lubricating oil to fill clean lubricating oil or change the suitable lubricating oil. According to the classification of single-stage pump impeller number: only a impeller on the pump shaft, it is strongly recommended that add a protective blanket cover when bearing removal operation to ensure the safe operation, and heat removal method of cone axis due to the end of the cone bearing inner ring two area is significantly different, usually for bearing inner ring end face to remove heat. Relevant data is as follows: roller press equipment parameters: hefei HFCG - Journal - mm Mm: cone, bearing type/CA/w - wear diameter mm。 Um um, such as the installation does not reach the designated position, slope, etc of the large amount of interference of the clearance is reduced, increasing friction heat production, soften surface, the early abnormal spalling. Choose suitable for the rolling bearing grease when choosing suitable grease, often need to consider the following factors: the type of bearing, speed, working temperature and load, and the installation location, sealing, shock and vibration, as well as the consideration and the environmental protection requirements. Don't rise the body break down the screw and remove the iron bowl ( This figure is borrowed) Remove the iron bowl after continue to screw down the screws, in turn, change into m * after unscrew the two screws. Bearing size for & amp; 众人; * NO, in the bearing level surface, piece of dial indicator, make the dial indicator rod head pointing in the direction of axis neck above, and compression. Note: heating heating does not exceed degrees Celsius, motor at run time because of the fan will produce negative pressure, so as to increase the oil inside and outside differential pressure, lead to the oil. But saved on an external plays a role of sealing grease, in order to prevent the liquid flow, grease on the friction parts of rolling bearing grease filling amount can be reference: a bearing inner don't fill grease, fill all the bearing inner cavity space / ~ / can. Shaft concentricity of the wrong is, cross cause axial jammed, we said today is voice is bigger and more particularly, to hear the noise of the special requires attention. Ring processing: bearing inner ring and outer ring processing varies according to the difference of the raw materials or blank form. According to understand, tell everyone in the process of using imported bearing, when it needs to be replaced a new bearing? Can be seen from the following points: mainly imported bearing inner ring and outer ring, rolling element and cage have crack or gap on any one; Imported bearing raceway surface, guard, with significant roller card injury; Imported bearing cage wear significantly, or rivet significant relaxation; Imported bearing ring, rolling body any fracture; Import on the raceway surface, rolling element bearing has serious indentation and mark; Imported bearing inner ring diameter or outer diameter surface has obvious creep; Imported bearing raceway surface, there are rust on rolling element and injury; Due to thermal change is obvious.
