Design and Use
- Hardened Teeth: The "H" suffix designates heat-treated teeth. This structural detail helps prevent premature tooth erosion under high load cycles.
- QD Style Component: Designed with a Type B hub configuration. It utilizes a split-tapered SDS bushing and standard cap screws to provide a secure, concentric clamp onto the machine shaft.
