132X54X48 Vacuum Suction Cup 1/3 Size Plastic Biesse Machinery Spare Parts

Replacing a one-third size vac seat on a Biesse CNC machining centre? This cup has a 132 x 54 mm top face and a 48 mm body, moulded in PF (phenol formaldehyde) plastic - a thermoset that holds its shape under clamp load and does not conduct electricity. Brown is standard and grey is also available; the same face is produced in 29 mm and 74 mm heights. Accessories: seal, ball valve, locating ring. Customization is supported. Price is quoted per order.

A vac seat that stops holding a panel normally fails in one of three ways: the seal goes flat and the sheet lifts mid-cut, the replacement pod sits at a different height so the whole grid has to be re-shimmed, or the plastic body cracks under clamp pressure and the seat is pulled out of the job. The 132X54X48 cup is the one-third size part for Biesse CNC machining centres, cut to the 132 x 54 mm face and 48 mm height those seats already take.

The body is PF, phenol formaldehyde plastic. As a thermoset it keeps its shape under clamp load, resists the friction of a panel dragged across the face, and does not conduct electricity, which keeps it predictable on a table carrying workholding and sensing equipment. Brown is the standard colour; grey is also available for shops that colour-code seating positions.

The same family comes in 29 mm, 48 mm and 74 mm heights, so a mixed table is re-padded from one source without changing the top face. Three service items are listed with the cup - seal, ball valve and locating ring - so a worn seal is replaced on its own. Customization is supported, and origin is China; price is quoted per order.

What decides whether the cup sits flush in the seat you already have:

• One-third size footprint - 132 x 54 mm top face, the compact seat size for smaller workpieces and tight configurations.
• 48 mm body - the standard height, quoted as 132X54X48 mm overall, so the cup sits at the plane of the seat it replaces.
• Two more heights, same face - 29 mm and 74 mm bodies share the 132 x 54 mm top face, so 3 heights cover a mixed table.
• PF thermoset body - phenol formaldehyde plastic, chosen for wear resistance and mechanical strength under clamp pressure and friction.
• Non-conductive material - PF does not conduct electricity, which keeps the cup predictable on a table with workholding and sensing equipment.
• Brown or grey - 2 colour options, so seats can be colour-coded by position or matched to the cups already fitted.
• Three service parts - seal, ball valve and locating ring are listed as available accessories.
• Customization supported - a modified seat is met with a drawing rather than a rework of an off-the-shelf cup.
• Built for Biesse machining centres - listed as machinery spare parts for Biesse CNC tables, in 1/3 size.

The awkward choice on a worn seat is to run it until a panel shifts, or to change the whole console set because the new cup is a different height. Neither is needed here.

• Replace one seat, not the set. One cracked body costs 1 cup, not a console set that has to be re-levelled.
• Height matching stops panel lift. 48 mm is the standard body, with 29 mm and 74 mm on the same 132 x 54 mm face, so the new cup lands at the plane of the old one.
• Thermoset instead of commodity plastic. A PF body keeps its shape under clamp load and resists friction from a dragged panel, so the face stays flat through a shift.
• One-third size reaches what a full pad cannot. At 132 x 54 mm the cup fits the small and tightly spaced seats where a larger pod will not go.
• Service parts, not whole assemblies. 3 items - seal, ball valve, locating ring - are listed separately, so a worn seal does not scrap the cup.
• Two colours keep the table readable. Brown standard, grey on request, so positions are coded by colour, not by labels.
• Custom seats are not a dead end. Customization is supported, so a shop with a modified seat is not tied to whatever off-the-shelf size is in stock.

Yes, if the seat takes a 132 x 54 mm cup. It is listed for Biesse CNC machining centres in 1/3 size, with a 132 x 54 mm top face and a 48 mm body - measure the cup you are pulling out before ordering.

132 x 54 mm on the top face and 48 mm high. Overall size is quoted as 132X54X48 mm, and the same top face is also produced in 29 mm and 74 mm bodies.

It is one-third of the full size, not a full pad. The top face is 132 x 54 mm, which makes it the compact seat for smaller workpieces and tightly spaced positions.

PF, phenol formaldehyde plastic. It is a thermoset, so it holds its shape under clamp pressure, resists friction and does not conduct electricity.

Yes. The 48 mm body is the standard one, and 29 mm and 74 mm are also available on the same 132 x 54 mm top face.

Yes. Brown is the standard colour and grey is also available, so the cup can be matched to the seats already on the table.

Yes. Customization is supported, so a modified seat or a non-standard batch is quoted from your drawing or sample rather than from the stock list.

No. The cup is quoted per order and seal, ball valve and locating ring are listed as available accessories - ask for them on the same enquiry so they ship together.
