HSK grippers / tool clamping – Bellodi

HSK tool grippers / spindle grippers

The HSK DIN 69893 grippers, also known as gripper units, are an essential component in spindles with automatic tool change (automatic clamping). These clamps have been designed and manufactured to the highest quality standards, in order to ensure the maximum transmission of force and torque possible. Thanks to the geometry of the sectors and the clamping cone, HSK clamps are able to multiply forces and make the system safer.

For years, the world’s leading manufacturers of machine tools and spindles operating in the Mechanical and Woodworking sectors (but also used for Glass and Marble sectors) have been using these HSK clamps.
For example, Breton machines use HSK A63 clamps.

Usually, these HSK clamps are mounted on spindles with HSK 63F, HSK 80, or other types of HSK tool holder cones. Additionally, they are fully interchangeable with OTT-JAKOB Spanntechnik Germany clamps.

The HSK grippers have been made with high-quality materials and have been treated to ensure high durability over time.

How do I identify the gripper I need?

If you need to replace the damaged gripper of your HSK spindle, you can easily identify it by reading the code printed on the body of the clamp. Otherwise, you can send us detailed photos of the clamp, including its measurements taken with a caliper, to the email address and our team will be happy to respond as soon as possible.
