Extra-thick top plates can be counter-bored to achieve proper clamping thickness (hold thickness to ±.127mm). Special-length Ball Lock Clamps are also available, as specials.

FEATURES: The Ball Lock Mounting System allows accurately locating and clamping at the same time, with just the turn of a hex wrench. Ideal for mounting quick-change tooling on a subplate. Each mount consists of three components: (1) a Ball Lock Clamp, with a precisely ground shank; (2) a Liner Bush in the top plate; (3) a Receiver Bush in the subplate. This compact assembly provides considerable holddown force, together with an incredible +/-.013mm repeatability!
SIZES: Available in the following shank diameters — see Dimensions page for part numbers:| | 13mm | | | 16mm | | | 20mm | | | 25mm | | | 30mm | | | 35mm | | | 50mm |
Each shank diameter is available in a choice of lengths for different top plate thicknesses (both inch and metric). Thick top plates can be counter-bored to use shorter clamps.
OPERATION: Turning the clamping screw with a hex wrench advances the large centre ball, pushing the three clamping balls outward. These balls engage the angled ID section of the Receiver Bush, pulling the clamp firmly downward.
DESIGN CONSIDERATIONS: Each top plate should have one ball lock mount designated as its primary reference point, and one as its secondary reference point. These two mounts should be as far apart as possible. The secondary reference point should have a relieved liner to avoid redundant location (binding). Additional Ball Lock Clamps can be used for more clamping force, but these should be installled in clearance holes, not locating liners. Note that the same Ball Lock Clamp fits into any type of liner or a clearance hole. Ball Lock Clamps must be used with Ball Lock ReceiverBushes for proper operation. Plate thickness must be +/-.127mm to achieve full clamping force. Do not exceed maximum screw torque shown.
MATERIAL: Clamp body > 4340 steel, heat treated Rc 40-45. Balls > 440C stainless. Screw > high-carbon steel, black oxide finish. O-ring > Rubber. |
