Care and maintenance
In addition to power density and precision, the special gearboxes from CHEMNITZER ZAHNRADFABRIK are characterised above all by their durability.
Depending on the application, regular maintenance of the gearboxes is recommended, i.e. regular checks and topping up of lubricants to ensure smooth operation of the gears and bearings. This also includes checking the seals and housings for leaks to prevent the ingress of dirt or moisture.
We will of course be happy to provide you with comprehensive advice during our joint development project – including on the subject of proper assembly or preventive maintenance.

we have only been here for 134 years.
What Does Proper Gearbox Maintenance Involve?
Regular maintenance isn’t a cost center—it’s a way to prevent breakdowns. What’s particularly important for special-purpose gearboxes:
Lubricant Management
Lubricant is the lifeblood of every gearbox. We recommend gear oils compliant with DIN 51517-3, tailored to the specific operating conditions. Regularly checking the oil level and oil quality—and, depending on operating hours, performing timely oil changes—significantly extends the service life of gears and bearings.
Seals and Housing
Leaking seals are often an early warning sign. Regular visual inspections for leaks, contamination, or moisture ingress help prevent major damage—before it occurs.
Bearings and Gears
Unusual noises, elevated operating temperatures, or changes in smoothness of operation are signs that should be taken seriously. We assist with root cause analysis and evaluating whether an inspection or replacement of components is warranted.
Installation and Commissioning
Much of the damage does not occur during operation, but rather during installation. We advise you on the proper installation and removal procedures and, upon request, provide installation instructions tailored to your specific gearbox.

Recommendation for gear oils
Depending on the operating conditions, we recommend using a gear oil that complies with DIN 51517-3 as the gear lubricant. The correct choice of oil depends on factors such as operating temperature, speed, gear ratio, and environmental conditions. Equivalent products from other manufacturers may also be used—we would be happy to advise you on your selection.
