    Bearing Characteristics

    Strong Bearing Capacity

    Mainly bears radial and axial combined loads dominated by radial loads, and generally does not bear axial loads alone.

    Separable Installation

    The inner and outer rings can be installed separately, and the axial clearance and radial clearance can be adjusted during installation, or pre-interference installation can be performed.

    Axial Displacement Limit

    Limits the axial displacement of the shaft or housing, ensuring that the shaft is not tilted relative to the housing or bore.

    Clearance Affects Life

    The precise adjustment of axial clearance in tapered roller bearings directly optimizes and extends operational life.

    Application Areas

    Machine Tool Industry

    Used in spindles, feed shafts, and high-precision components, effectively bearing cutting forces and rotational loads to ensure stability and accuracy.

    Automotive Industry

    Applied to wheel hubs, differentials, and transmissions to support wheel rotation while reliably transmitting power and torque.

    Reducer Industry

    Supports gear shafts in speed reducers, managing combined radial and axial forces to ensure smooth, continuous transmission.

    Mining Machinery

    Supports rotating components in heavy crushers and ball mills, reliably absorbing massive impact loads and severe radial stresses.

    Metallurgical Industry

    Withstands extreme rolling and axial forces across rolling mills and steel processing machinery for dependable, uninterrupted operation.
