The SCH hydraulic clamp is signified by its high clamping capacity in spite of its small size and low weight.
High clamping force easily replaces low weight manual bolts, does not require any space outside the die. Clamps within 5-10 seconds depending of number of clamps.
Inspect your T-slots, as on certain press tables the Tslots might be deformed or damaged. If this is the case, grinding should reshape the T-slots. Buying a holder helps maintain order around the press and protects the clamps against unnecessary damage.
Clamps can be delivered with extra heatproof seals (viton). For warm applications, for instance forging presses.
