Union, Compact Brgless CoolControl, M12x1.25 LH, 13 mm pilot
1159-003-137
- Single passage for all media
- Patented AutoSense™ technology changes automatically between closed seals and controlled leakage operation in response to the kind of media
- Non-rotating element has "stroke" (axial movement) of up to 13.5 mm, to track drawbar movement even when the union is mounted on the clamping device
- CoolControl™ technology utilizes an air pilot to hold seals closed during axial drawbar movements, thus mimimizing coolant leakage during tool change cycles
- Full-flow design has no obstructions to trap swarf or debris
- Balanced mechanical seals made from silicon carbide for long life even under difficult operating conditions
