CARB toroidal roller bearings are a new type of radial roller bearings. This compact self-aligning roller bearing was developed by SKF and was launched in 1995. The unique design of the bearing combines the self-aligning capability of a spherical roller bearing with the unrestricted axial displacement of a cylindrical roller bearing. It can also have a small cross-sectional area, which is usually the case with needle bearings.
Style design
Various designs of CARB toroidal roller bearings
(1) D≤>120mm reinforced polyamide 4.6
(2)120 (3) D>600 mm, brass cage (4) Self-guided roller realizes full roller CARB bearing (5) The load bearing capacity of the moving bearing is increased by about 30%. (6) Reduced speed limit (7) Sealed full-roller bearings for use in polluted environments (8) No maintenance, lifetime sealing (9) Low rotation or vibration CARB toroidal roller bearing features (1) Compact design (2) The unique internal geometry of the CARB bearing ensures uniform load between the roller and the raceway Distributed axial displacement (3) The axial displacement in the CARB bearing is about ±10% of the bearing width (4) The load between the roller and the raceway can always be evenly distributed to achieve the optimal operating condition alignment error. (5) CARB bearings can allow shaft eccentricity/alignment error of no more than 0.50 (6) will not reduce the life or increase friction (7) Average load distribution Advantages of the CARB toroidal roller: CARB bearings allow axial displacement without causing additional axial forces or friction. Therefore, the load in the new bearing system has only external radial and axial forces. The new bearing system offers customers the following advantages: (1) Lower bearing load (2) Improved bearing distribution (3) Relubrication interval is prolonged (4) It is possible to reduce the size (5) The service life of bearings and lubricants is significantly extended Application range of CARB toroidal roller: (1) Paper machine (2) continuous casting machine (3) crusher (4) Grinder (5) Industrial transmission (6) Conveyor belt (7) Textile machine
