109X54X18mm Round Vacuum Suction Cup Cover Rubber Plate Woodworking Machinery Tools

A worn vacuum cup cover causes three things at once: panels that slip a few millimetres mid-cut, a face marked where the bare cup touched it, and a line that stops while someone finds a pad that fits. This is the part that fixes all three. One-piece moulded rubber plate, 109 × 54 × 18 mm, grey and yellow, tear-resistant and flexible, pressed onto the vacuum cups of CNC machining centres, PTP machines and mechanical arms.

A plant running a CNC machining centre, a PTP machine or a robot arm meets the same three costs when the rubber on a vacuum cup wears: panels that slide a millimetre mid-cut, a face that comes back ringed where the cup touched it, and a line standing still while someone hunts for a pad that fits. All three come from one part, the plate on the cup.

This is that part: a round vacuum suction cup cover in rubber, one-time moulded as a single piece at 109 × 54 × 18 mm, in grey and yellow. Moulded in one shot rather than cut and glued, it has no seam for a vacuum to pull apart and no joint line to print on the workpiece. The compound is chosen for stick and tear resistance, so the lip keeps its shape through repeated press-and-lift cycles instead of curling off the seat, and stays flexible enough to conform to a panel that is not flat.

It fits the 109 mm round cups of CNC machining centres, PTP machines and mechanical arms — the woodworking machines sold under SCM and similar badges — wherever a cup holds flat panels. Fitting is by hand: press the plate onto the cup, check it sits down in the seat, lift it off when it is worn. Other sizes are moulded to request.

What separates this plate from a disc cut out of rubber sheet:

• One-piece moulded body — each cover is one moulding, one piece, so there is no glued joint at the lip.
• 109 × 54 × 18 mm envelope — made for 109 mm round vacuum cups; the 18 mm section sets the height the panel rides at.
• Tear-resistant rubber — the compound holds up to repeated press-and-lift cycles without the lip splitting.
• Strong stick, flexible edge — the plate grips the panel and keeps that grip while the vacuum is on.
• Grey and yellow — two-tone colour, so a glazed or torn cover is visible against a dark pod.
• Protects the cup as well — the rubber takes the contact, so the cup body is not chipped and the panel face is not marked.
• Fitted by hand — press on and lift off; no tools and no service call for a wear part.
• One part for three machine types — CNC machining centre, PTP machine and mechanical arm on the same 109 mm seat.
• Clean-and-inspect care — wash off dust and chips, look at the lip for cuts, replace when it is torn.
• Custom moulding available — other dimensions, colours and machinery accessories produced to your requirement.

When a cup cover goes glazed, torn or flat, a plant usually has two options: keep running and accept the slipped panels, or replace the whole vacuum cup. This plate is the third one.

• Replace the plate, not the cup. You are buying the 109 × 54 × 18 mm rubber cover, not a complete pod, so a wear item stops costing like a machine part.
• Fewer panels lost to slippage. A moulded rubber lip that still grips under vacuum is what holds the panel flat through the whole cut.
• No ring marks on the finished face. The rubber takes the contact instead of the cup, so faces that leave the machine clean stay clean.
• The height the pod was set for. The 18 mm section keeps the panel at its designed height, so drilling and cutting depths do not drift.
• One line item to keep in stock. One part number covers the three machine types that use a 109 mm round cup.
• Back in production the same shift. Press on by hand, check the seat, run again — no tools, no downtime waiting on a technician.
• Not locked to one colour or one size. If your pods take a different footprint, the same moulding process produces it to your drawing.

Only the cover. This is the round rubber plate that sits on top of the cup, 109 × 54 × 18 mm, not the cup body or the vacuum block underneath it.

Check the seat first: this plate is made for 109 mm round cups with a 54 mm centre and an 18 mm height. Measure the pad you are taking off — if it matches, it fits.

CNC machining centres, PTP machines and mechanical arms. It is a woodworking machine part, used wherever a 109 mm vacuum cup holds flat panels.

A worn, glazed or torn cup cover is the usual cause, not the pump. Once the lip no longer conforms and grips, vacuum leaks at the edge and the panel creeps; a fresh moulded plate restores the seal.

No. The rubber is what takes the contact, so the cup never touches the panel and the face is not ringed or scratched.

By hand, with no tools. Press it onto the cup, push it fully down into the seat, and lift it off the same way when it is worn.

Clean and inspect it. Wash off dust and chips, look at the lip for cuts or hardening, and replace the plate once it is torn — a worn cover is a vacuum leak, not a spare you can keep running.

Yes. Customised machinery accessories are produced to your requirement — send the drawing or the dimensions of the cup seat you need it to fit.
