Deep Groove Ball Bearing

1. High Load Capacity: The deep groove design of the inner and outer rings increases the contact area between the steel balls and the rings, enhancing load capacity. The presence of ribs on both sides of the inner and outer rings effectively prevents rolling elements from shifting, allowing the bearing to maintain stability under radial and axial loads, making it suitable for the complex loads generated by automotive drive shafts during high-speed operation.

2. Low Friction: The 6211 deep groove ball bearing is made from high-strength, wear-resistant materials. After heat treatment, it achieves high hardness, which reduces wear and friction, thereby improving the overall efficiency of the transmission system.

Tapered Roller Bearing

1. Adaptability to Complex Loads: The rollers of the NA48385 - 48320D tapered roller bearing operate with line contact on the raceways, providing a larger contact area to effectively distribute loads, allowing the bearing to simultaneously handle radial and axial combined loads.

2. Strong Wear Resistance: The NA48385 - 48320D tapered roller bearing is typically made from high-strength materials, offering excellent wear resistance and maintaining stable performance even under harsh conditions, thereby extending its service life.
