Single Row Tapered Roller Bearings NTN are designed so the inner/outer ring raceway and apex of the tapered rollers intersect at one point on the Bearing T-8578/8520 centerline. By receiving combined load from inner and outer ring, the rollers are pushed against the inner ring rib and guided by rib.
Induced force is produced in the axial direction when a radial load is applied, so must be handled by using a pair of Bearing T-8578/8520. The inner ring with rollers and outer ring come apart, thus facilitating mounting with clearance or preload. Assembled clearance is however hard to manage and requires special attention. Bearing T-8578/8520 are capable of supporting large loads in both the axial and radial directions.
Single Row Tapered Roller Bearings NTN with 4T-, ET-, T- and U attached to the Part number conform to ISO and JIS standards for sub- unit dimensions (nominal contact angle, nominal small end diameter of outer ring) and are internationally interchangeable.
Industrial Bearings Solutions also has a line of case hardened steel bearings Bearing T-8578/8520 designed for longer life (ETA-, ET-, etc.).Single Row Tapered Roller Bearings NTN also include Bearing T-8578/8520 with two and four row of tapered rollers for extra-heavy loads.
