Tapered roller bearings features cup and cone assembly with tapered rollers, where cup is the outer ring and cone consists of inner ring, rollers and cage both having matching tapered raceways on the inner and outer rings. Tapered roller bearings are rolling element bearings designed in a way that can support axial as well as radial loads. The axial load carrying capacity of tapered roller bearings increases with increasing taper angle. The higher the degree of angle, the greater the contact angle.
Cylindrical Roller Bearings comprises of cylindrical shaped rollers as the rolling elements along with inner ring, outer ring and cage. The rollers have a greater (linear) contact area with the outer ring and are capable to distribute loads across a broader surface. Cylindrical Roller Bearings have a high radial load capacity and are fit for high speeds. These bearings are built with a single row, two rows, or multi rows of rolling elements to meet an application’s radial load requirement.
CAGES: PRESSED STEEL CAGE, POLYAMIDE CAGE, MACHINED BRASS CAGE
BORE TYPE: CYLINDRICAL AND TAPER
Needle roller bearing is a special type of roller bearing which uses long, thin cylindrical rollers resembling needles. Needle bearings have rollers that are at least four times longer than their diameter. Needle roller bearings offer great rigidity and hence have the ability to handle a larger, more rigid shaft in a given application. These bearings have higher load carrying capacity than single row ball or roller bearings of comparable OD. Sometimes, to conserve space, the inner ring may be omitted and the needle rollers ride directly on the shaft.
