Characteristics and Applications of Toroidal Roller Bearings

CARB toroidal roller bearings are a revolutionary type of bearings that are automatically self-aligning like self-aligning roller bearings and axially free like cylindrical or needle roller bearings. CARB toroidal roller bearings can adapt to the misalignment and axial displacement within the bearings without incurring internal axial load and with little increase in friction, which eliminates the need for a tradeoff between a tight fit and an axial degree of freedom, thus allowing the tight fit to eliminate the "creep" and fretting corrosion common to conventional bearing arrangements. As a result, the operating temperatures are reduced, the vibration levels are declined, and the reliability is improved, the life of bearings and lubricants is prolonged, and the energy consumption is cut down. Upgraded CARB toroidal roller bearings provide longer service life, especially in working conditions where the bearings are subject to contaminants or the lubrication is poor.


Main features of CARB toroidal roller bearings:

(1) Compact design


(2) The unique internal geometry of CARB toroidal roller bearing ensures uniform axial displacement distribution of loads between rollers and raceways


(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, so as to achieve the best alignment error under operating conditions


(5) CARB bearings allow shaft eccentricity/alignment error not exceeding 0.50


(6) They will not reduce life or increase friction


(7) Average load distribution
