At Specialty Gear Drives, we specialize in the rapid
repair of Windmöller & Hölscher Gearboxes.
All Fields Must Be Filled Out
In the flexible packaging industry, print registration errors and extruder shutdowns cost thousands of dollars per hour in wasted film and resin. Whether you are running a blown film line or a CI flexo press, waiting for parts to ship from Lengerich, Germany is not an option. At Specialty Gear Drives, we specialize in the rapid repair of Windmöller & Hölscher Gearboxes. We return your precision German engineering to better-than-OEM condition, often saving you up to 60% compared to a new unit.
German Precision for the Global Market
Windmöller & Hölscher is the undisputed leader in machinery for flexible packaging. From the legendary VAREX blown film lines to the high-speed MIRAFLEX and NOVOFLEX printing presses, W&H equipment is built for 24/7 continuous production. These units rely on incredibly tight gear tolerances to maintain film gauge consistency and perfect print registration. However, the demands of high-speed printing and high-pressure extrusion eventually take their toll. When these complex drive systems fail, you need a repair partner who can match the original German manufacturing standards. You need Specialty Gear Drives.
Precision Gearing vs. Constant Load.
W&H drives face two distinct challenges: the massive axial thrust of extrusion and the high-speed precision of printing decks. We frequently analyze and repair:
On VAREX and OPTIMEX lines, screw back-pressure overloads the thrust bearing, often destroying the output shaft and housing bore.
On MIRAFLEX presses, microscopic wear on bull gears or pinions causes gear marking and registration loss.
Failure of the screw seal allows molten polymer to enter the gearbox, carbonizing oil and seizing bearings.
HELIOSTAR presses operate at high speeds where misalignment or bearing fatigue creates vibration that damages print quality.
Why We Are The Best In The Industry
German-Spec Rebuilding with In-House Gear Manufacturing We don’t just replace bearings; we restore the geometry of the drive. Because we Manufacture our own Gears, we can rebuild discontinued or long-lead-time W&H components in days.
We immediately pick up your unit, perform a full tear-down, steam clean, and CMM inspection.
Magnaflux and ultrasound testing detect sub-surface fatigue in case-hardened gears.
Helical and spiral bevel gears are manufactured in-house using DIN-standard alloys.
Out-of-round bearing bores are resleeved to restore OEM interference fits.
Premium SKF/FAG bearings and Viton seals installed for high-temperature operation.
