Product Overview: The 40 BWD 12 Double Row Angular Contact Ball Bearing
The 40 BWD 12 is a high-performance double row angular contact ball bearing, engineered specifically for demanding automotive applications, particularly as a wheel hub bearing. With principal dimensions of 40x74x40mm (Bore x Outer Diameter x Thickness), this bearing is designed to handle significant radial and axial loads in both directions simultaneously. Its construction features two rows of balls arranged back-to-back, providing high rigidity and a compact solution for wheel assemblies.
As a crucial component in our Angular Contact Ball Bearings category, the 40 BWD 12 is manufactured to precise standards to ensure optimal performance and vehicle safety. These bearings typically come pre-lubricated and sealed to protect against contamination from dirt, water, and road debris, ensuring a long, maintenance-free service life. Its robust design makes it an essential part for ensuring smooth and reliable operation of vehicle wheels.
Key Features of the 40 BWD 12 Bearing
- Double Row Design: Provides excellent capacity for combined radial and axial loads, making it ideal for wheel applications.
- High Rotational Accuracy: Precision manufacturing ensures minimal friction and smooth rotation, contributing to better vehicle handling.
- Pre-Greased and Sealed: Comes lubricated for life and sealed on both sides to prevent grease leakage and keep contaminants out.
- Durable Construction: Made from high-quality, hardened bearing steel for superior strength and resistance to wear and fatigue.
- Compact and Rigid: The integrated double row design offers high moment rigidity in a space-saving package, simplifying hub assembly.
- Optimized Internal Geometry: Engineered to distribute loads evenly across the rolling elements, maximizing operational life.
Common Applications of 40 BWD 12 Bearings
- Automotive Wheel Hubs: Primarily used in the front and rear wheel hubs of passenger cars and light commercial vehicles.
- Trailer Axles: Provides reliable support for trailer wheels, handling heavy loads and constant use.
- Agricultural Machinery: Suitable for the wheel hubs of tractors, harvesters, and other farm equipment.
- Industrial Gearboxes: Can be used in compact gearboxes where high combined load capacity is required.
- Conveyor Rollers: Offers robust support for heavy-duty conveyor systems.
- Small Vehicle Drivetrains: Applicable in certain ATV and utility vehicle powertrain and wheel assemblies.
Benefits of Using the 40 BWD 12 Bearing
- Enhanced Vehicle Safety: Ensures stable and reliable wheel rotation, which is critical for safe vehicle operation.
