High-Quality 32218 Taper Roller Bearing 90*160*42.5 from China Suppliers & Factory for Motorcycle Rear Wheel Hub

Exceptional Bearing Capacity: Our bearings are designed to withstand substantial radial and axial combined loads, primarily focusing on radial loads while not typically accommodating standalone axial loads. This makes them ideal for diverse applications across various industries.

Separable Installation for Enhanced Flexibility: These bearings feature a separable design, allowing the inner and outer rings to be installed independently. This allows for precise adjustments of axial and radial clearances during installation, or the option for pre-interference installation, thereby enhancing adaptability to your specific requirements.

As a leading factory and trusted suppliers in China, we ensure our products meet the highest standards of quality and performance, delivering exceptional value for your engineering needs.

    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 the housing, and does not allow the shaft to be tilted relative to the housing or hole.

    Clearance affects life

    The size of the axial clearance of the tapered roller bearing directly affects the operational service life of the bearing.

    Application Areas

    Machine Tool Industry

    Used in the spindle, feed shaft, and other core components, bearing cutting force and rotation load to ensure machining accuracy and stability.

    Automotive Industry

    Applied to wheel hubs, differentials, transmissions, and axles, supporting wheel rotation while smoothly transmitting power and torque.

    Reducer Industry

    Supports gear shafts within speed reducers, managing combined radial and axial forces generated during gear meshing.

    Mining Machinery

    Installed in crushers and ball mills to support heavy rotating elements under massive impact and radial loads.

    Metallurgical Industry

    Utilized across rolling mills and steel plant equipment to withstand heavy rolling forces and severe axial thrust.

    Frequently Asked Questions

    What are the critical boundary dimensions of the 32218 bearing?
    The 32218 metric tapered roller bearing has a bore diameter (d) of 90 mm, an outer diameter (D) of 160 mm, a total assembled width (T) of 42.5 mm, an inner ring width of 40 mm, and an outer ring width of 34 mm.
    Can 32218 tapered roller bearings handle both radial and axial loads?
    Yes, they are engineered to bear combined radial and axial loads dominated by radial forces. Due to the contact angle (15.642°), axial loads are accommodated in one direction and are usually installed in opposed pairs to handle bidirectional thrust.
    Why is clearance adjustment important during installation?
    Because tapered roller bearings have separable inner and outer rings, setting proper axial and radial clearance (or pre-load) directly determines the operating temperature, vibration levels, and overall service life of the assembly.
    What steel grade is used in manufacturing JITO tapered bearings?
    All standard bearings are manufactured from high-grade GCr15 chrome steel, ensuring high hardness, superior wear resistance, and long-term fatigue strength under heavy load conditions.
    Do you support OEM branding and customized packaging?
    Yes, we provide complete OEM services, including custom laser marking, branded box packaging, customized labels, barcode integration, and tailored crating/pallet solutions to meet client specifications.
    What is the standard warranty period for these bearings?
    We offer a standard 12-month quality warranty from the date of shipment against manufacturing and material defects under recommended operating and installation procedures.
