QJ 1064 MA Bearing Product Overview & Core Advantages
The QJ 1064 MA is a metric four-point contact ball bearing designed for applications requiring exceptional precision and load handling capabilities. This single-row bearing excels at simultaneously supporting combined radial and axial loads from both directions, making it an ideal solution for compact, high-rigidity arrangements. Manufactured to P6 (ABEC-3) tolerance class, it ensures reliable performance in demanding industrial environments. Its optimized design provides a high load rating while maintaining a relatively low cross-section, contributing to space-efficient machinery design.

QJ 1064 MA Bearing Structural Features & Performance Benefits
- Four-Point Contact Design: The unique raceway geometry enables the bearing to handle significant combined radial and axial loads in both directions, effectively replacing two single-row angular contact bearings in many applications.
- High Rigidity & Precision: Built to P6 tolerance class with precisely engineered raceways and chrome steel construction, this bearing delivers exceptional dimensional stability and rotational accuracy.
- Optimized Load Distribution: The design ensures optimal stress distribution across the four contact points, significantly enhancing bearing life and reliability under heavy loads.
- Quality Materials: Features chrome steel rings and balls for superior wear resistance, combined with a brass cage that ensures stable operation at moderate speeds.
- Ready-to-Use: Factory lubrication eliminates the need for initial greasing, simplifying installation and reducing maintenance requirements.
QJ 1064 MA Bearing Typical Application Areas
The QJ 1064 MA four-point contact ball bearing is particularly suited for:
- Industrial Robots and automation equipment requiring precise motion control
- Wind Turbine pitch and yaw control systems
- Machine Tool rotary tables and indexing heads
