Bearing tapered roller bearings are available in a wide range of designs and can also be customised to suit your specific speed, load, contamination, temperature or vibration conditions. Bearing tapered roller bearing have cup and tapered components. The cup consists of the outer ring and the tapered assembly consists of the inner ring, rollers and cage. This taper roller bearing construction can withstand combined loads and provides low friction in operation. Rigid applications of the bearings can be achieved by adjusting one single row tapered roller bearing relative to a second tapered roller bearing and applying a preload. Bearing tapered roller bearings are often used as a bearing solution in applications where improved performance, reduced friction or increased power density is required. Applications Common applications for these tapered roller bearings include automotive wheel bearings; as well as gearboxes, axle systems and engines Agricultural machinery shafts and general shafts as centre frame rollers, strip straighteners or in combination with guideway elements Helicopter transmissions Aircraft fuel pumps Specification Life expectancy Once a taper roller bearing component starts to spall material, the bearing is considered fatigued and immediate replacement is recommended. Life expectancy can be estimated according to ISO 281. This standard estimates bearing life based on 90% reliability of all roller bearings, taking into account variables such as material, build quality, type of load, operating conditions, lubrication and contamination.
