104859 103206 Rubber Washer Sealing Ring For KDT Gluing Spindle - KDT Spares

Product Description

Need to stop glue creeping out along the gluing spindle of a KDT edge bander? This is the ring that sits on that shaft: 40 x 20 x 8 mm, 20 mm bore, 40 mm outside diameter, moulded in high temperature resistant rubber and supplied in reddish brown. Part number 104859 103206. One ring seals one gluing spindle. Quote the number, or send the three measurements off the old ring, and the size is matched before the order is packed.

Glue trouble on an edge bander lands in the same three places: cured glue creeping out around the gluing spindle, a glue line that widens through the shift as the seal softens, and a replacement that arrives the wrong size. The 40 x 20 x 8 mm sealing ring for the KDT gluing spindle fixes the first two, and three caliper readings settle the third.

It is a flat rubber washer, moulded in high temperature resistant rubber. Three figures define it: 40 mm outside diameter, 20 mm bore and 8 mm thickness, leaving a 10 mm wall of rubber between bore and rim, which is the sealing body. It is listed as a spare for the gluing shaft of KDT edge banding machines.

The material is why the ring is specified rather than improvised. The compound is a high temperature resistant grade, and it works on the glue shaft, where heat is continuous. A ring that hardens there stops following the shaft, and the gap it leaves is where glue escapes.

Ordering takes one of two routes. If the old part number is readable, quote 104859 103206. If it is not, measure bore, outside diameter and thickness off the old ring and send the three figures. One ring seals one gluing spindle, so count spindles first.

Product Features

What the three figures mean on the machine, and what else decides the fit:

• 40 mm outside diameter — taken across the outside face of the ring; check it against the old part first.
• 20 mm bore — the inner diameter that goes over the gluing shaft, measured where the rubber wears most.
• 8 mm thickness — read with a caliper on the flat face, not on a compressed edge.
• 10 mm wall section — the rubber between the 20 mm bore and the 40 mm rim, which does the sealing.
• High temperature resistant rubber — the compound is specified for the glue shaft, where heat is continuous.
• Reddish brown colour — tells this ring apart from black washers on the same shelf.
• Flat washer form — thickness reads straight off a caliper, so the size is confirmed before the spindle comes apart.
• KDT gluing shaft fit — listed as a spare for the gluing spindle on KDT edge banding machines.
• One ring per spindle — the seal is a single ring, so order the number of gluing spindles being resealed.
• Part number 104859 103206 — reordering by number skips the measuring step and the wrong-size risk.

Product Advantages

When the seal on a gluing spindle goes, there are two ways out: replace the spindle assembly, or find the ring that matches it. The ring is the smaller of the two, and the only real risk is getting the size wrong.

• A ring instead of an assembly. What fails is the rubber, not the shaft, so 40 x 20 x 8 mm of rubber keeps the spindle that was already working.
• Measured, not guessed. Bore 20 mm, rim 40 mm, thickness 8 mm — three readings turn a part number into a size match.
• Heat held at the shaft. A high temperature resistant grade keeps its section on a shaft that runs hot through a whole shift.
• Glue stays in the joint. A ring that still follows the shaft keeps the bead where it belongs instead of leaving cured glue on the spindle.
• Colour as a check. Reddish brown is easy to confirm against the ring that came off, which catches a mix-up before the machine goes back together.
• Reorder without measuring. Once 104859 103206 is on the record, the next order is a number, not a caliper session.
• Spares planning. Rings sit in the hottest part of the glue path; one per spindle on the shelf avoids a stop while a single ring is on order.

Frequently Asked Questions

Which sealing ring fits the KDT gluing spindle?

This one: 40 x 20 x 8 mm, part number 104859 103206, for the gluing shaft of KDT edge banding machines. It is a flat rubber ring with a 20 mm bore and a 40 mm outside diameter, so the shaft side and the seat side both have a figure to check against.

How do I know the ring needs replacing?

Cured glue on the shaft is the usual sign. When the rubber stops following the shaft, glue escapes at that gap and sets, and the bead on the panel starts to widen through the shift instead of holding a steady line.

Can I order by measurement instead of the part number?

Yes. Three readings are enough: bore, outside diameter and thickness. Send 20 mm, 40 mm and 8 mm if the old ring measures the same, and the part number is confirmed against your figures rather than against a machine serial.

Is this just a standard rubber washer?

It is a washer in shape only. The compound is a high temperature resistant rubber grade, which is what separates it from a general-purpose washer on the same shaft, and the 40 x 20 x 8 mm size is what makes it a spindle part rather than a shim.

What material and colour is the ring?

High temperature resistant rubber, in reddish brown. The colour is a useful check: a black ring on the bench is not this part, and that is easier to spot than a 1 mm difference on a caliper.

How many rings do I need?

One per gluing spindle. Count the gluing spindles on the machine that are being resealed and order that number, because the ring is a single part and not a set of several washers.

Can I fit it to an edge bander from another brand?

Only after measuring. The ring is listed for the KDT gluing spindle, so on another brand compare all three figures — 40 mm, 20 mm and 8 mm — before ordering, rather than assuming the same nominal size means the same seat.

What should I send with an enquiry?

The part number 104859 103206, or the three measurements off the old ring, plus the quantity and the machine model. With those figures the price and the size are answered in one reply instead of three.
