At Specialty Gear Drives, we specialize in the emergency repair, rebuild, and in-house manufacturing of Kissling gearboxes — from heavy industrial drives to ski lift ropeway gear units. Our Timken-certified technicians restore your Kissling unit to better-than-OEM condition with some of the fastest turnaround times in the country.
All Fields Must Be Filled Out
Kissling has been engineering precision gear units since 1925 — building their global reputation on ropeway and ski lift gear units that debuted on the world stage at the 1960 Squaw Valley Winter Olympics. Today, Kissling gearboxes power everything from mountain gondolas and chairlifts to cement mills, sugar refineries, and amusement park rides. When one of these critical units goes down, Specialty Gear Drives is ready to get it back online fast.
Most repair shops use hydraulic presses to install bearings — a method that can stress the bearing race and shorten service life. At Specialty Gear Drives, we use liquid nitrogen to thermally shrink each shaft, then drop a super-heated bearing into place. Gravity and physics do the work, creating a perfect interference fit without any stress on the component. The result is a longer-lasting bearing installation that meets or exceeds OEM specifications — every time.
Whether you’re operating a ski resort with a lift out of service, a cement plant with a downed conveyor drive, or a processing facility with a failed ropeway unit — downtime on Kissling equipment is urgent. Specialty Gear Drives has the technicians, tooling, and in-house manufacturing capability to handle any Kissling repair, fast.
We repair both current-model and legacy Kissling gearboxes across their full product line. Our blueprint archive and reverse engineering capabilities mean we can manufacture parts for units that are no longer in OEM production — keeping older equipment running without costly replacement.
From standard industrial gear units to massive ropeway drives, our shop handles the full Kissling product range — including discontinued and hard-to-source legacy models.
Kissling's flagship product — ropeway gear units with torque ratings from 120 kNm to 570 kNm. We repair gondolas, chairlifts, T-bars, and cable-driven transport systems of all configurations.
Heavy-duty Kissling standard gear units used across cement, sugar, mining, and general manufacturing. We restore these to full OEM specification, including all housing and shaft work.
Kissling planetary gearboxes designed for high-torque, compact applications. We disassemble, inspect, and rebuild every carrier, ring gear, and sun gear to exact dimensional tolerances.
Including the specialized 16 hydraulic twin and 8 single motor pinion configurations used in rollercoasters and high-cycle amusement applications — fully supported by our engineering team.
Kissling narrow gear units and straight bevel configurations for space-constrained industrial applications. We manufacture replacement gearing in-house when OEM parts are no longer available.
Legacy and custom-built Kissling gearboxes no longer supported by OEM parts supply. Our blueprint archive and reverse engineering capabilities keep these critical units running.
When a Kissling gear or shaft is beyond repair, we produce a new one on-site. Our CNC gear-cutting center handles all profiles across the Kissling product range, with diameters up to 20 feet.
Even the most ruggedly built Kissling units are vulnerable to certain failure modes under sustained operational stress. Our diagnostics team identifies the root cause before any repair begins.
High-cycle loads in ropeway and industrial applications cause progressive surface fatigue. Early pitting accelerates to spalling and tooth fracture if not addressed at the first sign of wear.
Axial load spikes from cable tension and shock events cause premature thrust bearing failure in Kissling ropeway units. We replace all bearings using our liquid nitrogen installation process.
Continuous-duty operations generate sustained thermal loads that degrade lubricant, seals, and eventually the gear mesh itself.
Shaft seal wear allows lubricant escape and contamination ingress. Outdoor ropeway environments accelerate internal damage.
Cyclic torsional loads and misalignment cause fretting corrosion and keyway damage. We recondition or manufacture new shafts to OEM tolerances.
Bearing migration and shock loads damage housing bores, causing misalignment. Precision line-boring restores exact geometry.
Vibration signatures indicate worn gear mesh, loose components, or imbalance — all corrected during full rebuild.
Outdoor installations allow water, dust, and debris ingress. We fully clean, inspect, and restore all affected parts.
A disciplined, documented rebuild process — no shortcuts, no guesswork. Every Kissling gearbox leaves our shop certified and tested.
We arrange no-cost freight pickup anywhere in the US. Your Kissling gearbox is logged, assigned to a dedicated technician, and disassembly begins immediately upon arrival.
All components go through our industrial parts washer using an organic cleaning solution to strip all grease, grime, and rust — revealing every fault clearly before any measurement begins.
Every gear, shaft, bearing journal, and housing bore is measured and documented, then compared against Kissling OEM tolerances.
Worn gears and shafts are manufactured in-house, matching original hardness ratings and dimensional specifications with fast turnaround.
Reassembled with Timken-certified bearings, new seals, gaskets, and high-temp polymer coating to reduce vibration and overheating.
Each gearbox completes a 6-hour load test monitored for vibration, heat, and leaks before certification with our 24-month warranty.
We manufacture Kissling gears on-site. No OEM backorders — just precision parts cut to spec and ready in days.
Every Kissling rebuild is covered from the moment it goes back into production — the strongest guarantee available.
Pickup and delivery at no cost to you, anywhere in the US. We handle all logistics from door to door.
A Specialty Gear Drives rebuild costs a fraction of sourcing a new Kissling unit, with equal or better reliability.
Our technicians hold the same certifications demanded by OEM service centers — ensuring every repair meets the highest industry standard.
We maintain blueprints for every Kissling model we've ever serviced — including discontinued and legacy units no longer supported by the manufacturer.
Ski lift down? Production line stopped? Our emergency team is available around the clock to accelerate your Kissling repair turnaround.
Call us and our repair coordinators — all former field technicians — can often diagnose your Kissling gearbox failure over the phone before the unit even ships.
