It rolls body to be whether cylinder roll son to the heart rolling bearing.
Cylinder roll son dish keep in touch the bearing for line with roll. Load ability is great, mainly bear radial load. Roll body and one set of circles and block friction is small, suitable for rotating at a high speed. Whether it is blocked that according to one set of circles, can divide uniline bearings such as NU, NJ, NUP, N, NF,etc., and pair such as NNU, NN list the bearing. This bearing is structure that an inner circle, outer lane can be separated. Inner circle or outer lane have cylinder to block side roll sub bearing, its inner circle and outer lane can to relatively move axially, so can serve as free end bearing. Have pair block sets of circle of the other side have, block cylinder of side, get away sub bearing singly in inner circle with some of outer lane, can bear the axial load of a direction to a certain degree. Generally use the stencil plate to press and keep the shelf, or the copper alloy car makes and keeps the shelf. Use polyamide to take shape and keep the shelf while being some too.
Roll son dish keep in touch or build, roll off the production line, keep in touch for line, radial bearing capacity loud with roll, suitable for bearing carrying on one’s shoulder or back and impact load of heavy load.
The coefficient of friction is small, suitable for the high speed, the terminal rotational speed is close to the deep ditch ball bearing.
N type and NU type can move axially, can adapt to the axle caused by thermal expansion or installation error and change of outer cover relative position, can make the end of freedom to support and use.
Expect relatively much to the processing of the axle or seat hole, the axis of the outer lane is relatively askew to add and control severely after the bearing is installed, so as not to cause and exposed to the stress centralizedly.
The inner circle or outer lane can be separated, easy to install and dismantling.
Large and medium sized motor, rolling stock, main shaft of the lathe, internal-combustion engine, generator, gas turbine, gearbox, rolling mill, shaking sifting and handling machinery,etc..
