BTH-0068AA Truck Wheel Hub Bearings 105x165x140mm Double Row Ball Bearingsd Drivetrain Systems.

Product Name: BTH-0068AA Truck Wheel Hub Bearings 105x165x140mm Double Row Ball Bearings

Description:
The BTH-0068AA is a heavy-duty double-row angular contact ball bearing, precision-engineered for truck and commercial vehicle wheel hub applications. Manufactured from high-quality GCr15 chrome steel, this bearing features a C3 internal clearance and P0 precision rating, ensuring reliable performance under the extreme radial and axial loads, high torque, and severe rotational stresses encountered in heavy-duty vehicle suspension and drivetrain systems.

This bearing incorporates double rubber seals (2RS) on both sides to provide superior protection against water, mud, dust, and other contaminants, making it exceptionally durable in harsh on-road and off-road operating environments. The nylon cage ensures precise ball spacing, minimizes friction, and promotes smooth operation, while the chrome steel balls deliver excellent wear resistance and load-carrying capacity. The angular contact design allows the bearing to accommodate combined loads (radial and axial simultaneously) with high rigidity and stability.

Machined to precise 105x165x140mm dimensions, this robust, non-standard bearing offers outstanding load distribution, shock load resistance, and extended service life, making it a reliable solution for demanding commercial vehicle applications.

Applications:
This bearing is specifically designed for truck and heavy-duty automobile wheel hub replacement, providing dependable performance and long-term durability for medium and heavy-duty trucks, buses, and commercial vehicles operating under challenging driving conditions.

Additional Technical Insight (Double-Row Angular Contact Ball Bearing)

The BTH-0068AA is a double-row angular contact ball bearing, a premium design for heavy-duty wheel hub applications.

• Type & Structure: It consists of two rows of balls positioned between the inner and outer rings, with raceways designed at an angle to the bearing axis. This angular contact geometry allows the bearing to support significant combined loads (radial and axial forces) simultaneously.

• Features: The double-row configuration provides high rigidity and excellent load-carrying capacity in a compact assembly. The angular contact design enables the bearing to handle axial loads in both directions, making it particularly suitable for wheel hub applications where cornering forces, braking, and acceleration impose complex load patterns.

• Advantages: Key benefits include superior combined load capacity, high structural rigidity, excellent shock load resistance, and stable performance under high-speed and high-temperature conditions. The 2RS rubber seals provide enhanced contamination protection for extended service life.

• Target Applications: Primarily used in truck wheel hubs, commercial vehicle axles, and heavy-duty automotive systems. This bearing type is also widely found in construction equipment, agricultural machinery, gearboxes, and industrial applications where high load capacity and reliability are critical.
