Vacuum Block Vacuum Rubber Suction Cup 120x50x100mm 2-056-17-0960 Replacement

Need the vacuum block under a slipping panel, without a service call? This one is a 120 × 50 × 100 mm block with a 120 × 50 mm rubber pad on a rubber-and-plastic body, sold as a replacement for 2-056-17-0960 and 2056170960. It is used on CNC machining centres and PTP machines, including HOMAG machining centres. 100 mm height keeps the Z reference of the cup you are removing. Grey standard colour, other sizes on request, OEM customisation offered, packed in plastic bags and carton boxes, price quoted per enquiry.

A shop holding panels on a nesting table hits three problems: a rubber pad gone hard so the workpiece creeps mid-cut, a block that no longer sits flat so the seal leaks at one corner, and a replacement with the wrong footprint that forces the fixture to be re-set. This block removes all three.

It is a vacuum block: a plastic body with a bonded rubber pad on top, 120 × 50 × 100 mm overall. The pad is 120 × 50 mm — the face the panel is pulled onto — and the height is 100 mm, which decides how far the panel rides above the table. Because that height is fixed, the fixture keeps its Z reference when this block replaces a worn cup.

Material is rubber + plastic: the plastic shell takes the clamping load, the rubber pad seals and compresses against the panel. Grey is standard. Other sizes are available on request, and OEM customisation is offered.

It replaces 2-056-17-0960 and 2056170960, both printed in the table below, so the store can match it without measuring. Use it on CNC machining centres, PTP machines and other vacuum-table routers. Packing is plastic bags and carton boxes, so the pad arrives without grit pressed into it.

Eight things decide whether a vacuum block survives a shift on a nesting table.

• Measured, not nominal — the pad is 120 × 50 mm, the block 120 × 50 × 100 mm, so seal area and footprint are two numbers a caliper can check.
• Height holds your Z reference — 100 mm from base to pad face, so tool paths need no re-zeroing after a swap.
• Plastic body, rubber face — the shell carries the clamping load, the pad does the sealing, hence rubber + plastic rather than one moulded material.
• Two part numbers, one item — 2-056-17-0960 and 2056170960 both map to this block.
• Built for table clamping — CNC machining centres, PTP machines and other vacuum tables, including HOMAG centres taking the 120 mm class of cup.
• Packed to protect the pad — plastic bags and carton boxes, each block bagged so the rubber is not abraded in transit.
• Other sizes on request — 120 × 50 × 100 mm is the stock block; other footprints are quoted to drawing or sample.
• OEM marking offered — Grey is standard, and blocks can be supplied under a reseller's own label.

The real choice is between running a worn cup until a panel slips and paying a call-out for a part that costs less than the downtime it prevents.

• The panel stays put. a flat 120 × 50 mm rubber face seals over its whole area, not on a few high spots left on a compressed old pad.
• No re-teaching after a swap. 100 mm height matches the cup being replaced, so a block can be changed mid-job without touching the Z offset.
• Order by number, not by photo. 2-056-17-0960 and 2056170960 are both on the item, so nobody measures the old block or emails a picture to the supplier.
• One stores line, several machines. the same block serves CNC machining centres and PTP machines running the 120 mm class of cup, so spares do not multiply with every machine on the floor.
• Cheap to hold. bagged individually in carton boxes and quoted per enquiry, a shop can keep two or three instead of the single spare that never gets reordered.
• Wear stays visible. the grey flat face shows a lifted edge or an embedded chip before the seal fails, which is when it should be changed.
• Works on a mixed floor. other sizes and OEM customisation let a shop running several machine brands move onto one cup standard.

It replaces 2-056-17-0960 and 2056170960. Both numbers are printed on the item and in the parameter table, so either number can be quoted when ordering the same 120 × 50 × 100 mm block.

It will if the machine takes the 120 mm class of vacuum cup. The block is used on CNC machining centres and PTP machines, including HOMAG machining centres; check two figures against the cup you are removing — the 120 × 50 mm pad footprint and the 100 mm height. Those two numbers decide the fit.

Yes, it is the one dimension that changes the job. 100 mm is the distance from base to pad face, so a different height moves the panel up or down and forces a Z re-zero. This block is 100 mm.

Both. The part is listed as rubber + plastic: the plastic body takes the clamping load and holds the shape, the rubber pad on top does the sealing against the panel.

Yes. The 120 × 50 × 100 mm block is the stock size; other sizes are available on request and are quoted against your drawing, sample or old part.

Yes. OEM customisation is offered, so the block can be supplied for a reseller or a workshop group ordering under its own label.

It ships in plastic bags and carton boxes, each block bagged so the pad face is protected. Price is quoted per enquiry — send the part number and the quantity you need.

Grey is the standard colour. It is a plain compound, not a marking, and grey is chosen on purpose: wear, a lifted edge and embedded chips show up sooner than on a dark pad, so the block gets changed before the seal gives up on a cut.
