The advantage of importing bearing SKF insulating bearing is classified with application


31st March 2013 Bearing Technology 0 Comments
Import the advantage of the bearing SKF insulating bearing SKF insulating bearing can prevent the damage that the electrical erosion causes, applies to the electrical machinery and can guarantee to operate more reliably compared with ordinary bearing. And compared with other isolation methods, accord with interest benefit and reliable further. Physical dimension and basic fundamental characteristic of the insulating bearing are the same as non- insulating bearing, by a hundred per cent interconversion. Recommend importing the application knowledge of the bearing SKF insulating bearing for ...

Supply the rectilinear motion bearing


31st March 2013 Bearing Technology 0 Comments
Rectilinear motion bearing Structure and use of the ball bearing of rectilinear motion: ? Its structure of ball bearing of the rectilinear motion contains the hold unit within the outer lane, the hold unit contains a plurality of steel balls, and do endless loop sports. Spring collar fixed within the both ends of hold unit, set up jaggy window in every steel ball the intersection of straight line and the intersection of orbit and side worked to force. This part makes and is done roller contact by loaded steel ball and axle. Use very low friction coefficient relative movement, so the ...

Several kinds of reasons and methods to solve why the bearing of the centrifugal machine generates heat


31st March 2013 Bearing Technology 0 Comments
But the most key problem origin lies in whether this INA bearing is traditional, some users will be in order to choose the bearing of the low price cheap, but this kind of bearing is very easy to generate heat, hot, will even burn the bearing. Thus I want to choose the traditional bearing. Because traditional high-quality bearing can guarantee centrifugal machine temporary to run normally, its life-span that runs can be up to more than 10 years. In addition, should look out for the mechanical lubrication, will be chosen the good high-temperature lithium saponify, the quality of the in fact ...

Anneal deoiling dispel static, dusting spraying dry 1.Annealing The plastics are apt to form internal stress when shaped, the stress concentration place is apt to fracture after coating. Can adopt the annealing treatment or surface to deal with, stress-relieved. Annealing treatment is to heat ABS plastic formed part to the heat distortion temperature, namely 60 ℃, thermal insulation 2h. Because it needs a large amount of equipment investment to adopt this kind of craft, so, the technology that can adopt the surface and deal with, namely dispose the treatment to that the surface of the model ...
