● Heavy-duty spring for heavy-duty applications.
● Built-in oil free bushing has good wear resistance, which enhances life time.
● Non-return function is available.
● Handling workpiece with height difference.
● For working condition in which shock absorption is required during handling process
● For working condition fo short operating cycle and fast movement.
● Non-return function is available for oval suction cup.
◇ Note：1. Pretightening force is spring elastic force when spring is compressed in natural state.
2. Elastic force is the spring elastic force when level compensator is compressed to 50% stroke, it is suggested that the real compressed
stroke in working should not exceed 50% of the max. compressed stroke of the level compensator.
3. Vertical load refered to the maximum vertical tension that the compensator can bear in static state.
4. When the compensator is installed horizontally, the gravity generated by the workpiece perpendicular to the direction of the
compensator may cause the spring to be stuck, if it is larger than the horizontal load range.
