4004180021 Sealing Locking Washer SCHNORR VS 6 VERZ-F-ST For Homag CNC Machine

The 4004180021 Sealing Locking Washer is a SCHNORR VS 6 VERZ.F.ST locking washer for Homag CNC machines. It combines a locking function with sealing to keep dust and moisture out of critical assemblies. The washer is made in China by Shunhongyu and ships in a standard export carton box. To confirm fit, check your Homag machine parts list for part number 4-004-18-0021 or 4004180021. The washer is durable and precise, and it is a direct replacement for the original SCHNORR VS 6 VERZ.F.ST washer.

When a Homag CNC machine loses clamping force or starts letting dust into a sealed joint, the cause is often a flattened or corroded locking washer. The 4004180021 Sealing Locking Washer restores both the lock and the seal at that point. Without it, the joint can loosen and contaminants can reach the bearing surface.

This is a SCHNORR VS 6 VERZ.F.ST sealing locking washer, part number 4-004-18-0021. It fits Homag CNC machines and is categorized as a woodworking machinery accessory. The washer is made in China by Shunhongyu. To confirm fit, match the part number 4-004-18-0021 or 4004180021 against your machine's parts list or the old washer.

Check the mating surface for wear and confirm the washer seats flat before tightening. The sealing lip must face the side that needs protection from dust and moisture. A correctly seated washer keeps the joint locked and sealed through machine vibration. If the old washer is crushed or pitted, replace it rather than reuse it.

The washer is packed in a standard export carton box. No customisation is stated for this part. When you enquire, send the part number 4-004-18-0021 or 4004180021, the machine model, and the quantity you need. That lets the supplier check stock against your Homag CNC machine without back-and-forth.

What the specification fixes, and what it leaves to the machine:

• Dual lock and seal — The washer provides a locking mechanism and a sealing function at the same joint, so one part handles both retention and contamination protection.
• Homag CNC fit — Designed for Homag CNC machines, the washer integrates into the machine structure where the original SCHNORR VS 6 VERZ.F.ST washer was fitted.
• Part number match — Confirm fit by matching 4-004-18-0021 or 4004180021 against your Homag parts list or the marking on the old washer.
• Dust and moisture barrier — The sealing function blocks dust, moisture and other contaminants from entering the joint, protecting the bearing surface behind the washer.
• Vibration resistance — As a locking washer, it resists loosening under the vibration that CNC machining generates, keeping the fastened joint secure during operation.
• Durable construction — Built for industrial use, the washer is durable enough to hold its lock and seal through repeated machine cycles without crushing early.
• Precise dimensions — Precise manufacturing means the washer seats correctly on the mating surface, so the seal contacts evenly and the lock engages as intended.
• Seat check before fitting — Inspect the mating surface for wear and confirm the washer sits flat before tightening; a raised or pitted seat will break the seal.

What changes on the shop floor when the right part goes back in:

• Restores joint security. A fresh locking washer brings back the clamping security that a flattened or corroded washer has lost, so the assembly stays tight through CNC vibration.
• Keeps contaminants out. The sealing action blocks dust and moisture at the joint, which protects the bearing surface and reduces the chance of premature wear inside the machine.
• One part, two jobs. Because the washer locks and seals at the same point, you carry one part number instead of separate locking and sealing components for that joint.
• Easy fit confirmation. Matching 4-004-18-0021 or 4004180021 to your Homag parts list takes minutes, so you order the right washer the first time and avoid returns.
• Built for repeat cycles. Durable construction means the washer holds its lock and seal through repeated machine cycles, so you replace it less often during normal maintenance.
• Precise seating. Precise dimensions let the washer seat flat on the mating surface, which gives even seal contact and reliable locking without shimming or adjustment.
• Simple stock planning. Packed in a standard export carton box and available in quantity, the washer is easy to keep on the shelf as a maintenance spare for Homag CNC machines.

Check your machine's parts list for 4-004-18-0021 or 4004180021. If either number appears for the joint you are repairing, this SCHNORR VS 6 VERZ.F.ST washer is the matching part.

It locks the joint against vibration and seals it against dust and moisture at the same time. That dual function protects the bearing surface behind the washer.

Replace it when the old washer is crushed, pitted or no longer seals. A flattened washer loses clamping force and lets contaminants into the joint.

Face the sealing lip toward the side that needs protection from dust and moisture. Reversing it lets contaminants past the seal and defeats the purpose.

No, fit a new washer if the old one is crushed or pitted. A reused washer may not lock or seal correctly, which puts the joint at risk.
