1. cylindrical roller this kind of roller mainly uses in the cylindrical roller bearing, but also may use in directly the roller module in the machinery.This kind of roller has standardized in the size, may supply the design and the user choice as the commodity roller.
2. long cylindrical roller this kind of roller minute has the axle diameter with with without the axle diameter with two kinds, mainly uses in the long cylindrical roller bearing, but also may use in directly the roller module in the machinery.
3. roller pin this kind of rollers mainly use in the needle bearing, the universal joint needle bearing and the thrust force needle bearing, but also may use in directly the roller pin module in the machinery.This kind of roller serialized in the size, for design choice.According to the bearing structure need, the roller pin both sides nose shape has the cone headed shape, the flat head shape, the round head shape and so on.
4. circular cone rollers assume the round frustum, its cone angle usually for 1°~4°20 ', also has is smaller than 1° or is bigger than 4°20 ', many for 2°.The roller length does not surpass the roller big end diameter generally two times.This kind of roller uses in the circular cone roller bearings, the big cone angle roller basically uses in the thrust force circular cone roller bearings.
5. spherical surface roller roller trundle delivering in person ball face shape.Uses this kind of roller the bearing to have the automatic accent heart performance, can withstand the very big load.The spherical surface roller divides asymmetrical and the symmetrical figure, the common asymmetrical big end surface is the spherical surface, the symmetrical figure two end surfaces is the even end surface.The symmetrical figure spherical surface roller performance is good, but asymmetrical is the elimination form.This kind of roller uses in adjusting the heart roller bearings and the thrust force adjusts the heart roller bearings.
6. spiral rollers it is the hollow roller which becomes with the special section steel reel system, divides the laevo rotatory and the dextrorotary two kinds.This kind of roller application not very widespread, mainly uses in the impact load spiral roller bearings.
7. prop hole roller prop hole roller center belt through hole, this hole uses for to install the prop, in order to fix on the laminated prop retainer.This kind of roller shape has the cylinder, the cone, the ball face shape, mainly uses in the extra large type bearing.
