OTT-JAKOB’s Hollow Shank drawbars and grippers are specifically designed for modern toolholding standards, including HSK, KM, and Capto/PSC. With their lightweight construction and integrated force intensification, these systems ensure optimal tool retention with minimal impact on spindle dynamics. Perfect for shops looking to push the limits of speed and accuracy.
| Key Features | |
| Force Intensifying Mechanism | Integrated force intensifier delivers high clamping force while maintaining a lightweight, dynamic-friendly design. |
| Lightweight Construction | Reduced mass minimizes the impact on spindle bearings and improves overall machine dynamics—ideal for high-speed machining. |
| Precision Clamping | Ensures accurate tool retention and consistent performance across all major hollow shank standards (HSK, KM, Capto/PSC). |
| Long Service Life | Maintenance-free components are built to last, even in demanding production environments. |
| Optional Integrated Monitoring | Sensor packages available for tool presence detection and real-time clamping force monitoring. |
Thanks to the geometry of the OTT-JAKOB HSK-Clamping-Units, the gripper segments move in parallel, clamping the tool between two surfaces. This ensures optimal power and torque transmission.
The design of the gripper segments and clamping cone enables reliable transmission and enhanced pull-in force.
To provide maximum protection against wear, the surfaces of the gripper segments and clamping cone are coated with a high-quality material, ensuring low friction coefficients.
The Type K HSK is the most economical option among OTT-JAKOB's HSK-Clamping-Units. As a robust foundational model, it is ideal for typical applications. Its premium coating ensures durability and longevity.
Type B HSK was designed to fulfill the unique needs of the automotive sector. This high-efficiency clamping unit is engineered for rapid and frequent tool changes. The restricted guidance ensures parallel movement of the grippers even in challenging conditions. Its enhanced DLC coating provides maximum longevity, while the minimized friction results in a higher transmission ratio.
Type C HSK enables exceptionally quick tool-change times. The integrated holding function reduces waiting time during the tool-change process. Additionally, our top-grade, optimized DLC coating ensures a prolonged lifespan.
Similar to the Type B, this clamping unit offers an increased transmission ratio or pull-in force while maintaining the same internal contour.
For the shortest possible spindle lengths, there are multiple options of Type B grippers but in a shorter format for the Type BK.
In the machining process, it can often be difficult for machinists to chase down the source of particular issues. Poor surface finish, rapid tool wear, taper corrosion, machine downtime, and tool breakage can each have multiple causes. However, there is one thing that can impact all of these: the pull-force of a spindle’s tool clamping system.
