7006 Angular Contact Ball Bearing | 7006C / 7006AC / 7006B
The 7006 angular contact ball bearing is a versatile single-row precision bearing designed to handle combined radial and axial loads. It features low friction, low noise and stable high-speed operation, making it ideal for precision transmission and industrial machinery. Available in three contact angle variants including 7006C, 7006AC and 7006B, plus bearing steel and stainless steel material options, this bearing adapts to standard, humid and light corrosive working environments.
Difference Between 7006C, 7006AC and 7006B
7006C (15° Contact Angle): Adopts a 15° contact angle with minimal friction loss and excellent high-speed stability. It delivers superior rotational precision with moderate axial load capacity, perfect for high-speed spindles and precision automation equipment.
7006AC (25° Contact Angle): Features a 25° contact angle with balanced radial and axial load performance. It offers stable composite load resistance and cost-effective usability, serving as the universal model for most standard precision machinery applications.
7006B (40° Contact Angle): Equipped with a 40° large contact angle for enhanced axial load capacity. It excels at bearing heavy axial forces under low to medium speed conditions, ideal for offset load and heavy thrust mechanical systems.
Material Differences: Bearing Steel vs Stainless Steel
Bearing Steel (GCr15): GCr15 bearing steel is the standard material for 7006 series bearings. After professional heat treatment, it provides high hardness, exceptional wear resistance and strong fatigue resistance, ensuring stable precision and long service life in conventional dry industrial conditions.
Stainless Steel: Stainless steel 7006 bearings provide outstanding rust and oxidation resistance. They effectively withstand moisture, humid air and minor contamination, preventing precision degradation and corrosion failure, suitable for food machinery, medical devices and high-humidity sanitary environments.
Product Features
Supports combined radial and axial loads for multi-directional force bearing. Three contact angle designs cover high-speed, universal and heavy axial load scenarios. High precision, smooth rotation and low noise performance. Dual material options balance cost efficiency and anti-corrosion capability. Standard compact structure enables easy installation and replacement.
Application Scenarios
7006 series angular contact ball bearings are widely used in precision motors, machine tool spindles, industrial pumps, compressors, instrumentation and automated precision machinery. Bearing steel models apply to conventional indoor industrial equipment; stainless steel versions fit sanitary, damp and corrosive working scenarios. 7006C is for high-speed precision operation, 7006AC for general universal use, and 7006B for heavy axial load equipment.
