HOH SERIES Counter Balanced Power Chucks
| |
Three-jaw wedge style power chucks are ideal for ultra high speed applications. They provide maximum gripping force at high speeds. Their unique built-in counter balanced mechanism assures stabilized jaw force every time. These deliver consistent accuracy and repetitive chucking. Counter balance allows for lower pressure gripping which is suitable for thin wall materials.
U.S. Patent No. 4410192 |
Special Features

Uses can vary from those high-speed operations requiring heavy jaw forces for roughing work to those requiring light jaw forces for preventing part distortions. This Counter Balanced Chuck design assures accurate, repetitive chucking.
Model HOH chucks are ultra high speed three-jaw counter balanced open center power chucks, direct mounted on ASA B5.9 type A pindles.
Model HOH chucks are manufactured from high grade alloy steel. All sliding surfaces are hardened and ground for accurate actual running and long service repeatability.
Lubrication nipple in each base jaw.
Base Jaw Serration: Chuck size 6" to 15": 1.5mm x 60°
Mounting: Direct mounting to fit ASA B5.9 type A (interchangeable with DIN 55026). DIN 55021, 55022 and 55027 mounting are available on request.
Standard Equipment: Chuck assembled with adapter, chuck mounting bolts. T-nuts and jaw mounting bolts with wrench. Draw nut wrench.
