4-035-01-0670 Original Short Stroke Cylinder For Homag Machine KHZ D63 HUB50

When a short stroke cylinder on a Homag machine loses force or starts to stick, the result is inconsistent clamping, poor feed control, or a stop that will not hold position. The 4-035-01-0670 addresses that specific failure by replacing the worn cylinder with one that matches the original KHZ D63 HUB50 G1/4 KDU=7 specification.

This is a short stroke cylinder with a 63 mm diameter and a 50 mm stroke length. The air port is threaded G1/4. It fits Homag machines that use the KHZ D63 HUB50 G1/4 KDU=7 cylinder.

Before mounting, check that the G1/4 port matches your air line fitting and that the 50 mm stroke suits the mechanism it drives. The cylinder mounts in place of the original, using the same G1/4 connection. In use, the 63 mm diameter provides the clamping force for the application, and the 50 mm stroke gives the travel needed for the machine function.

Supply comes as the cylinder alone; no additional packing or customisation is stated. For an accurate quote, send the Homag number 4-035-01-0670, the full specification KHZ D63 HUB50 G1/4 KDU=7, and the quantity you need. A photo of the existing cylinder's markings helps confirm you receive the correct replacement.

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

• Direct replacement for worn cylinders — The 4-035-01-0670 replaces the original short stroke cylinder on Homag machines, restoring the 50 mm stroke and 63 mm diameter without modification.
• Bore size for clamping force — A 63 mm diameter gives the cylinder the bore area needed to produce clamping force for the machine's hold-down or feed mechanism.
• Stroke length for travel — The 50 mm stroke length provides the travel required by the mechanism, matching the HUB50 designation on the original cylinder.
• Air port thread — The G1/4 thread connects to standard pneumatic fittings, so you can reuse existing air line connections without adapters.
• Fitment check by Homag number — Confirm the Homag number 4-035-01-0670 on the old cylinder or in the machine manual before ordering to ensure a direct fit.
• KHZ series identification — The KHZ designation identifies the cylinder series, helping you match the replacement to the machine's original specification.
• KDU=7 specification — The KDU=7 marking on the cylinder indicates the original configuration, so you can verify the replacement matches the old unit.
• Mounting without modification — The cylinder mounts in place of the original using the same G1/4 port and 50 mm stroke, so no changes to the machine are needed.

What changes on the shop floor once the unit is in place:

• Restores original machine performance. By matching the 63 mm diameter and 50 mm stroke, the 4-035-01-0670 brings the cylinder's force and travel back to the original specification, so the machine runs as intended.
• Avoids guesswork on fitment. The Homag number 4-035-01-0670 and the KHZ D63 HUB50 G1/4 KDU=7 marking give you two clear references to check against the old part, reducing the risk of ordering the wrong cylinder.
• Keeps air line connections simple. The G1/4 thread means you can reuse existing pneumatic fittings and hose, so installation does not require new adapters or changes to the air supply layout.
• Cuts downtime from cylinder failure. A sticking or weak cylinder stops the machine; having the correct replacement 4-035-01-0670 on hand lets you swap it out and get back to production faster.
• Maintains clamping consistency. With the correct 63 mm bore and 50 mm stroke, the cylinder delivers consistent clamping force stroke after stroke, helping hold tolerances on machined parts.
• Matches the original specification. The KHZ D63 HUB50 G1/4 KDU=7 specification matches the original cylinder, so you are not fitting a modified part that could alter machine behaviour.

Check the Homag number 4-035-01-0670 on the old cylinder or in the machine manual. Also verify the KHZ D63 HUB50 G1/4 KDU=7 marking on the cylinder body to confirm it matches your original part.

This is a short stroke cylinder with a 50 mm stroke and 63 mm diameter, designed for Homag machines. A standard cylinder may have different dimensions, so match the KHZ D63 HUB50 G1/4 KDU=7 specification.

The air port is threaded G1/4. This is a common pneumatic thread, so your existing G1/4 fittings should connect directly.

The 4-035-01-0670 is supplied as a complete short stroke cylinder. If the bore or rod is worn, replacing the complete cylinder is the reliable option.

Send the Homag number 4-035-01-0670, the full specification KHZ D63 HUB50 G1/4 KDU=7, the quantity required, and a photo of the old cylinder's markings if possible.

The cylinder is supplied as the unit itself. Fittings and air lines are not stated as included, so reuse your existing G1/4 fittings.

Mount the cylinder in place of the original, connect the G1/4 air line, and secure it. Check that the 50 mm stroke aligns with the mechanism before running the machine.

Seal wear, contamination in the air supply, or mechanical damage can cause sticking or loss of force. Replacing with the 4-035-01-0670 restores the original 63 mm bore and 50 mm stroke performance.
