4004210019 Spring RING J 22X1.00 V - Spare Part for Homag Woodworking Machine

This is a Spring Ring J, part number 4004210019, a retaining ring for Homag woodworking machines. It has a 22 mm inner diameter and 1.00 mm thickness, made from Federstahl (spring steel). To confirm fitment, check that your machine uses a 22 mm inner diameter by 1.00 mm thick J-type spring ring, and cross-reference the part number 4004210019 or 4-004-21-0019 in your manual or parts list.

When a retaining ring loses tension on a Homag machine shaft, components can shift axially, causing misalignment or unexpected downtime. This Spring Ring J 22X1,00 V addresses that failure by providing a fresh, spring-steel ring that grips the shaft and keeps parts in position. It is a direct replacement for worn or broken rings of the same size.

The part is a J-type spring ring with a 22 mm inner diameter and 1.00 mm thickness, made from Federstahl (spring steel). It fits Homag woodworking machines that use this size and type. To confirm fitment, check your machine's parts list for part number 4004210019 or 4-004-21-0019, and verify the shaft diameter matches the 22 mm inner diameter.

During installation, ensure the ring seats fully in its groove and that the J-type orientation matches the original. The spring steel construction allows the ring to flex and return to shape, maintaining tension under vibration. Inspect the groove for wear before fitting, as a damaged groove can reduce retaining force even with a new ring.

Supply comes as the spring ring only, with no additional packaging or customisation stated. When enquiring, send the part number 4004210019 or 4-004-21-0019, the quantity needed, and the machine model to confirm compatibility. SHUNHONGYU supplies various woodworking machine parts, contact us now.

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

• Shaft retention — The 22 mm inner diameter grips a matching shaft to prevent axial movement of components during machine operation.
• Spring steel construction — Federstahl material provides elasticity and wear resistance, allowing the ring to flex and return to shape without permanent deformation.
• J-type profile — The J-type design secures the ring in its groove, maintaining position under vibration and dynamic loads in Homag machines.
• Thickness for groove fit — At 1.00 mm thick, the ring fits grooves designed for this thickness, ensuring proper seating and retaining force.
• Direct replacement — Part number 4004210019 or 4-004-21-0019 cross-references to the original, simplifying ordering and reducing fitment errors.
• Homag compatibility — Designed for Homag woodworking machines, this ring matches the specifications of the original part for reliable performance.
• Wear resistance — Spring steel resists wear from repeated flexing and vibration, extending service life compared to softer materials.
• Installation check — Inspect the groove for wear before fitting; a damaged groove can reduce retaining force even with a new ring.
• Vibration resistance — The spring tension keeps the ring seated under vibration, preventing loosening that could lead to component movement.

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

• Keeps shafts running true. A fresh spring ring maintains axial positioning, reducing misalignment that can cause vibration and premature wear on bearings and seals.
• Cuts unplanned downtime. Having the correct 22 mm by 1.00 mm ring on hand means you can replace a failed ring quickly, getting the machine back into production without waiting for parts.
• Resists fatigue failure. Federstahl spring steel withstands repeated flexing, so the ring keeps its tension longer than mild steel alternatives, reducing replacement frequency.
• Simplifies part identification. The part number 4004210019 and 4-004-21-0019 are clearly marked, making it easy to reorder the exact ring without measuring or guessing.
• Maintains holding force. The J-type profile and 1.00 mm thickness ensure the ring seats properly in the groove, providing consistent retaining force under load.
• Reduces component damage. By preventing axial movement, the ring protects adjacent components from rubbing and impact, extending the life of shafts and gears.
• Easy to specify. With the 22 mm inner diameter and 1.00 mm thickness, buyers can quickly check against their machine's parts list or shaft size.
• It fits the machine you already run. The spring ring is made for woodworking machines, so it returns to the same shaft, bracket or spindle without re-machining the mounting.

Check your machine's parts list for part number 4004210019 or 4-004-21-0019 and confirm the shaft uses a 22 mm inner diameter by 1.00 mm thick J-type ring.

The inner diameter is 22 mm and the thickness is 1.00 mm, as specified for this J-type spring ring.

It is made from Federstahl (spring steel), which provides the elasticity and wear resistance needed for retaining applications.

The part is identified by Homag part numbers 4004210019 and 4-004-21-0019, but we do not state the manufacturer; confirm with your parts list.

Seat the ring fully in its groove with the J-type orientation matching the original, and inspect the groove for wear before fitting.

It may fit other machines that require a 22 mm inner diameter by 1.00 mm thick J-type spring ring, but always verify the part number and dimensions.

Send the part number 4004210019 or 4-004-21-0019, the quantity you need, and your machine model so we can confirm compatibility.

No customisation or special packaging is stated; the ring is supplied as a standard spare part.
