THK BWH Series High-Speed Double-Row Angular Contact Roller Ring
The THK BWH Series High-Speed Double-Row Angular Contact Roller Ring uses two rows of balls between the inner and outer rings, combining high rigidity and rotational accuracy with high-speed rotary performance. Its integrated ring structure and built-in preload eliminate the need for preload adjustment during installation.
The BWH Series features integrated mounting holes, allowing direct attachment to shafts and housings without a separate holder. This helps simplify installation while maintaining a compact rotary bearing arrangement.
Designed for sustained high-speed operation, the BWH Series achieved a Dpw·N value of 300,000 in testing while keeping temperature rise below 15°C during continuous operation. This makes it well suited to high-speed rotary tables and precision rotary mechanisms where both speed and accuracy are important.
