Bearing in the manufacture of complete and qualified by examination, or cleaning and rust prevention treatment, then put inside the package to achieve the water, moisture, dust, shock, maintaining the quality and precision bearings, and ease of use and sale purposes. Packaging materials bearing a polyethylene plastic tube (box), kraft paper, plain and wrinkles polyethylene paper, cartons, polyethylene or polyethylene plastic film, the preparation of nylon or plastic fastened with fastening tape,

Roller bearing in the operation of the process will inevitably damage occurred, if abnormal heat, vibration and noise increase of the phenomenon of sudden, that Roller bearing may have been damaged should be checked in time and analyze causes. Common failure modes are:  A, indentation    When the outside world durum substances into the bearing, and pressure in between the rolling element and raceway, make rolling surface indentation. In addition,

There are a number of bearings in a special kind of bearing, needle bearing axis is called the 10 bytes. Then for its maintenance, we need to look at! Automotive drive shaft 10 bytes on the request of lubricating materials in addition to have a good anti-friction and abrasion resistance, there should be a good mechanical stability, high temperature resistance (high drop point), corrosion resistance, water resistance and oxidation stability and other characteristics. 

This is due to open most of the bearings in the grease has been squeezed out, and the grease in sealed bearings have also been the cause leakage.    With the increase in the amount of grease filled, bearing linear temperature increase, the same filling volume, sealed bearing temperature rise was higher than open bearings.   Is generally believed that sealed roller bearing grease fill quantity, up to a maximum of 50% of interior space. Shawki and Mokhtar experiment, the ball bearing to 20-30% is most suitable

Vibration characteristics of vibration motor itself makes it easy to have problems, its parts tend to have shorter life expectancy. Bearing a variety of reasons, vibrating motor in use all kinds of problems occur, Tianjin Han Huang Precision Trade Co., Ltd., after summing up the past, many of the problems found in these issues, because customers do not understand or vibrating screen vibrating motor Install and use the result of failure in the majority. This makes us feel that if he let customers learn more

A lot of experienced mechanical maintenance technicians will usually run the sound through the machine to determine whether the device is normal, Tianjin Han Huang Precision Trade Co., Ltd. technical staff to summarize past experience bearing on the motor used to analyze the sound for example. 1, a continuous buzzing sound "hum ...":Analysis: Motor no load operation is to issue similar to the buzzing sound the same, and the occurrence of axial motor abnormal vibration, open or shut down the "Om" sound.

Bearing during use, there will be a variety of situations! Shaft hole closure is a common fault, how to fix it? A, can race with the new 1755 cleaning agent bearing hole surface for repairs.B, detection of wear of shaft and hole depth, diameter, if the wear depth in the direction of less than 4mm (ie the radial direction is less than 2mm), application of power tools to repair parts to be polished better. Note: Do not polished surface is too light, the rougher the better.

Bearing installation, to consider the extent of other parts of the match, which required not only for the bearing itself, and it wants to meet for the parts also have requirements. As the precision bearings within its accuracy 1μm, so ask its match components (shaft, bearing, end caps, ring, etc.) have very high dimensional accuracy and shape accuracy, especially with the precision to control surface and bearing the same levels, and this point is crucial, but also the most easily overlooked.
