10x8mm BIESSE Beam Saw Pressure Bar Strip Beam Saw Spare Parts Gaskit FNAG103417

The pressure bar strip is the rubber that sits between the clamping bar and the panel on a beam saw; when it hardens, the saw marks the board it is meant to hold. This one is 10 x 8 mm, grey, rubber, for the Biesse Selco SK4 beam saw. It sells by the metre with a 50 m minimum and ships in 1 to 7 working days, so a whole bar can be re-rubbered in one order.

A hardened pressure strip does not stop the saw. It lets the clamping bar slide on the panel instead, so the cut comes out with a scuff along the trim line and the operator starts adding clamp pressure to compensate. The saw still cuts; the finish is what changes.

This strip replaces that rubber on the Biesse Selco SK4 beam saw. Section is 10 x 8 mm, grey, in rubber. It is supplied as strip rather than a moulded pad, which is why it is quoted by length: the 50 m minimum covers a full clamping bar with enough left for the corners.

The rubber is the working face. It has to compress under clamp pressure and release cleanly, along the whole bar, without going hard at one end first. When it does harden the symptom is local: one zone of the bar marks panels and the rest does not, which is easy to mistake for a level fault.

Ordering is by length. Give the bar length in metres, add the waste you want for cutting and corners, and the strip is supplied to that figure with a 50 m minimum. Standard packaging, and the stated lead time is 1 to 7 working days.

What the section and the supply format decide:

• 10 x 8 mm section — 10 mm across the bar face, 8 mm of thickness under the clamp; both numbers come off the bar's groove, not off the old strip alone.
• Biesse Selco SK4 fit — listed for the Biesse Selco SK4 470 beam saw, so the section matches that clamping bar.
• Supplied as strip — quoted and shipped by length, which is what allows a full bar to be re-rubbered in one piece.
• 50 m minimum — enough for a complete clamping bar with cutting allowance.
• Grey rubber — visibly different from a fresh black strip, so worn zones can be located along the bar.
• 1 to 7 working days — stated lead time for this strip.
• Standard packaging — coiled and packed for transport without kinking the section.
• Wear part — the strip is the replaceable element in the clamping bar assembly.
• Working face, not structure — the strip carries no load beyond its own 8 mm of compression; the clamping bar behind it does the holding.
• Cut to length on site — a 50 m order covers a full bar plus allowance, and the offcut is kept for the next bar on the same machine.

What re-rubbering the bar actually fixes:

• Clamp marks disappear at the source. The 10 x 8 mm strip is what touches the panel; replace it and the scuff line stops being transferred to every board.
• Whole bar, one order. At 50 m minimum you re-rubber the full clamping bar instead of patching the worn zone, so pressure is even along its whole length.
• Cut on site, not pre-cut. Strip format means the length matches your bar after the old rubber comes off, including corners and end runs.
• Fast restock. The stated 1 to 7 working days lead time keeps a bar from sitting idle for a month.
• Local wear becomes visible. Grey strip against a used black one shows at a glance which part of the bar has hardened.
• Known section. 10 x 8 mm is the whole specification for fit; there is no profile to match beyond it.
• Spare length on the shelf. Re-rubbering a bar from a 50 m roll leaves enough strip for the corners and one repair, so the next failure does not start with another purchase order.

It is listed for the Biesse Selco SK4 470, section 10 x 8 mm. Check the section in your clamping bar: 10 mm across and 8 mm thick. If your bar takes a different section, this is the wrong item.

By length, with a 50 m minimum order. Give the bar length plus cutting allowance and that is the quantity.

The stated lead time is 1 to 7 working days. Packaging is standard.

Clamp marks on the panel, a scuff line along the trim, or a panel that creeps during the stroke. All three come from the rubber going hard rather than from the saw.

It is supplied as continuous strip and cut to the bar, so one bar takes one length plus the allowance you leave for corners.

Grey, as listed for this part.

You can, but pressure then varies along the bar, which is the condition that produced the marks. The 50 m minimum is sized for a whole bar.
