Cylindrical roller and raceway are line contact bearings. Cylindrical roller bearings without flanges on the inner or outer rings. The inner and outer rings can be moved relatively axially, so they can be used as free-end bearings. A cylindrical roller bearing with double rib on one side of the inner ring. And outer ring and a single rib on the other side of the ring can withstand a certain degree of axial load in one direction. The general use of steel stamping cage, or copper alloy car body cage. But some of them use polyamide shaped cages.
Cylindrical roller and raceway line contact, radial load capacity. It is suitable for bearing heavy load and impact load as well as high-speed rotation.
Cylindrical roller bearing raceway and rolling body geometry. After the improved design, with higher load carrying capacity, the new structure design of the flange and roller face. It not only improves the axial load carrying capacity of the bearing. But also improves the lubrication condition of the contact area between the roller end face and the flange.
Accuracy Grade Cylindrical roller bearings can be divided into P6, P5, P4, P2 according to accuracy grade. Order of accuracy grade from low to high.
Structure and Features of High Load Capacity Cylindrical Roller Bearings:
A ring made of resin material is designed between the rollers to prevent the rollers from contacting each other. Moreover, on the separate rings that are independently separated from each other. Because the tension generated by the roller clutch does not work, the thickness can be thinned. Thereby increasing the size and number of rollers.
High load capacity cylindrical roller bearings have the following advantages:
- The size and number of long-life rollers are optimized, so that the load capacity is increased. And the rated life of the bearing is more than 1.5 times that of the bearing with cage whose original size has not changed.
- High speed prevents roller contact in full roller bearings, optimizes the shape and guiding method of the spacer ring. And achieves the same allowable rotation speed and scratch resistance as bearings with cages.
- Operability Even if the inner ring is removed without the roller falling off. The inner ring and outer ring components can be installed separately to make it easier to install on the machine.
