Can be divided into two major kinds according to the kind of the rolling element: Ball bearing Ball bearing ,Its rolling element is a ball. Roller bearing Roller bearing ,Its rolling element is the column. Can be divided into several kinds as follows according to the loading effect direction born by it: The bearing entad: Can only bear radial load ' Such as short cylindrical roller bearing entad ,Can while bearing radial load, bear big axial load such as ball bearing entad The thrust bearing entad: Can bear and jointly support radially and axially, and can take radial load or ...

The backlash is an important factor whether the bearing could work normally. Choose the suitable bearing backlash, can make load distributed rationally among rolling element; Can restrain axle from ' Or outer cover Axial and radial displacement that axle in order to guaranteeing rotatory for precision; Make the bearing can work at the temperature that is required normally; Can reduce vibration and noise when the bearing work,etc., therefore, there is very great influence on bearing life-span, Wen Sheng, vibration and noise in the backlash of bearing. While choosing the backlash of bearing, ...

Recently, univesal a new technology of bearing company - -" radius of curvature SR measurement method of datum plane of roller ball " ,Awarded the patent for invention by State Intellectual Property Bureau. This is the 4th patent that a univesal bearing company succeeds in declaring this year, it has already the acquired patent of this year of univesal group exceeded 140 items for. The intangible assets are developed limitlessly. The patent is the valuable intangible assets of enterprise as a kind of intellectual property right, the maximum rights of enterprises are monopolizing legally if ...

The internal and external cycle sum rolling elements of the antifriction bearing adopt high chromium steel GCr15 or GCr15SiMn two kinds of bearing steels to make, the hardness of the finished bearing ring is in Lip river HRC60-65; The hardness of rolling element of the finished bearing is in Lip river HRC60-66. Among them, the ball hardness made of GCr15 bearing steel is within the range of Lip river HRC62-66; The hardness of the roller made of GCr15SiMn bearing steel is within the range of Lip river HRC60-66 in Lip river HRC60-64, steel ball. ...

The bearing, in fact just at our side, and consumption is surprising. Take car as examples, generally want to use 100 to 150 bearings in a car, without the bearing, the wheel will chuckle and bang, the gear of the change-speed gear box is unable to engage, the car will be unable to go. Not merely the car, rolling stock, plane, washing machine, refrigerator, air conditioner, dust collector, copying machine, computer, at the artificial satellite that fly in the remote space even, there is a figure of the bearing. The bearing is raising mechanical operating efficiency and energy-conserving ...

The antifriction bearing is the accurate basic part, therefore demand to hold a cautious attitude while using accordingly, use the high-performance bearing, if improperly use, can't reach the anticipated characteristic result either. So, should pay attention to the following items while using the bearing: 1,Keep the cleaning of bearing and ambient enviroment, has already made the invisible minification dust of naked eye enter the bearing, also will increase the abrasion, vibration and noise of the bearing. So, of the detachable bearing should be very clean, the clean indoor where the ...

Scoop dredge bearing installation and dismantlement method, should and make according to the structure, size and property of cooperating with bearing part of the scoop dredge one of the bearing of the scoop dredge. The pressure installed, dismantled should be added on the scoop dredge bearing trip ring end of the close fit directly, can't transmit pressure through the intersection of scoop dredge and the intersection of bearing and rolling element, because can surface cause impression in work by the intersection of scoop dredge and bearing in this way, influence the bearing normal operation ...

First, main function of the antifriction bearing: Under guaranteeing the bearing has enough life-span conditions, rotate or swing in order to support Part, transmit load, reduce friction during the movement pair, enable its rotation or swing Flexible. Second, basic demand of the bearing: Can meet the intersection of working condition and required load, rotational speed, working precision, dynamic characteristic ' Noise, vibration , ambient temperature and life time. Third, basic structure of antifriction bearing: By inner circle, outer lane, rolling element and retainer ' Commonly ...

The bearing is the essential part in the mechanical equipment, it is in our daily life, also the consumption is surprising, take car as examples, a car should generally have 100 to 150 bearings, if without bearing, the wheel will chuckle and bang, the unable gear join of gear of the change-speed gear box. The car will be unable to go. It is not merely a car, the application and extensive of the bearing, for example, rolling stock, space shuttle, wind-powered electricity field, washing machine, the refrigerator,etc. all have a figure of the bearing. The bearing is raising mechanical ...
