Specification

Related introduction

1. Dimensions: The inner diameter is 40 mm, the outer diameter is 75 mm, and the height is 39 mm.
2. Material: It is made of chromium steel, which features high hardness and excellent wear resistance, ensuring the service life and performance stability of the bearing.
3. Structural Features: It belongs to a double - row ball bearing and can withstand both radial and axial loads. It has a rubber seal or metal shield structure, which can effectively prevent impurities such as dust and moisture from entering. It adopts grease or oil lubrication methods to reduce friction and wear.
4. Applicable Vehicle Models: It is suitable for various vehicle models, such as the front wheels of Dongfeng Fengshen A30. It can also be used as an original replacement part for some models of brands like Mazda. The OE codes include 90363 - 40079, VKBA6878, etc.
5. Performance Advantages: It has a relatively high precision, which can reduce wear and extend the service life. It also has good corrosion resistance.

Applications

Small cars: Wheel bearings ensure stable wheel rotation and bear the weight of the vehicle itself, as well as the loads of passengers and luggage. During driving, they must withstand the impact of road bumps, as well as various forces generated during acceleration, braking, and cornering, ensuring driving comfort and safety. For example, in urban driving conditions with frequent starts, stops, and turns, wheel bearings need to possess good durability and precision retention.

SUVs and MPVs: These vehicles typically have larger interior spaces and higher load capacities, requiring wheel bearings to withstand greater vertical loads. Additionally, some SUVs may involve light off-road driving, necessitating wheel bearings to adapt to the impacts and vibrations from complex road conditions and maintain normal wheel operation.

Excavators: On construction sites, excavator wheel bearings must withstand enormous working loads and harsh operating environments. For example, during excavation operations, the vehicle needs to move and turn frequently; the wheel bearings must not only support the vehicle's weight but also withstand the additional impact forces from the digging motion.

Loaders: Used for loading and transporting materials, load loads vary frequently and significantly, although their operating speed is not high. Wheel bearings must possess excellent load-bearing capacity and fatigue resistance to withstand high-intensity, frequently changing working conditions.

Road rollers: Compacting the road surface with their own weight, their wheel bearings must withstand significant vertical static and vibration loads. Simultaneously, they must ensure the stability of the road roller and the compaction effect under different road surface conditions.

Motorcycles: Wheel bearings are crucial for the handling and driving safety of motorcycles. During high-speed riding, sharp turns, and braking, wheel bearings must withstand corresponding loads to ensure stable wheel rotation. Different types of motorcycles, such as racing motorcycles, cruisers, and motocross bikes, have different performance requirements for wheel bearings. For example, racing motorcycles emphasize lightweight design and high-speed performance, while motocross bikes emphasize impact resistance and adaptability to complex road conditions.
 
Bicycles: While wheel bearings on ordinary bicycles ensure smooth riding, for high-end products such as mountain bikes and road bikes, the quality and performance of the wheel bearings directly affect riding efficiency and experience. For example, when riding a mountain bike on rugged mountain roads, the wheel bearings must withstand significant impact forces and vibrations to ensure wheel stability and ease of rider control.

Educate Your Customers About Preventative Maintenance!

If a greaseable Universal Joint is installed, periodically inspect your Universal Joints for proper greasing approximately every oil change.
Inspect the yoke that holds your Universal Joint for cracks and stress marks.
Check your seals for signs of leakage and replace if seals are leaking.
Periodically check for drive shaft play, an indication of Universal Joint or seal failure.
Inspect drive shaft for cracks, stress marks, dents and bends and replace if necessary.
