HIGH SPEED CHUCKS HR counter centrifugal chucks use a system of counter weights in the chuck to reduce the jaw force losses that occur in chucks at higher speeds. This allows you to control work-holding pressure that can distort your part. These chucks also have a longer jaw travel, which allows for more clearance in part loading. HR High speed chucks can be used on your existing machine with out changing the cylinder in most cases. These chucks are heavy duty in their design and will out last most chucks that Come as OEM equipment. They are ideal for production applications as well as jobs, which require multiple jaw changes because of their repeatability.
