At Specialty Gear Drives, we specialize in the repair, rebuild, and in-house manufacturing of Cleveland gearboxes used in steel mills, refineries, chemical plants, mining operations, and paper manufacturing. Our Timken-certified technicians restore Cleveland industrial drives to better-than-OEM condition — fast, cost-effectively, and backed by a 24-month warranty.
All Fields Must Be Filled Out
Heavy Industrial Expertise
Cleveland gearboxes are engineered for reliability in the most demanding heavy industrial environments — steel mills, oil refineries, chemical processing, mining, and paper manufacturing. When a Cleveland unit fails, production stops and replacement costs through OEM channels can be significant. Specialty Gear Drives provides a faster, more cost-effective path: full in-house repair, rebuild, and precision gear manufacturing that matches Cleveland’s original specifications.
Our shop handles Cleveland gearboxes across all configurations — from precision boring and shaft reconditioning to complete gear manufacturing. Every component is restored or manufactured to original or improved specifications with strict quality control throughout the process.
When an Cleveland gear or shaft is beyond repair, we produce a precision replacement on-site matching OEM hardness ratings and dimensional tolerances — up to 20 feet in diameter.
Cleveland gearboxes operate under extreme industrial loads. Our diagnostics team identifies the exact root cause before any repair begins — ensuring the same failure doesn’t recur.
Sustained heavy loads in steel mill and mining applications cause progressive surface fatigue on gear profiles. Pitting and spalling require immediate expert intervention to prevent complete tooth fracture.
Continuous-duty industrial applications place extreme bearing loads on Cleveland units. We replace all bearings with Timken-certified equivalents installed via our liquid nitrogen thermal process.
Worn shaft seals allow lubricant loss and contamination ingress — particularly in mining and chemical plant environments where particulate and chemical exposure are constant operating realities.
Continuous-duty operations at elevated ambient temperatures in steel mills and refineries push Cleveland units beyond thermal limits when lubrication degrades or cooling systems are inadequate.
High-torque shock loads in mill and mining applications cause shaft fretting, keyway damage, and journal wear requiring precision reconditioning or new shaft manufacture in our on-site machine shop.
Bearing migration and impact loading cause housing bore deterioration. Our precision line-boring equipment restores all critical diameters to Cleveland OEM tolerances in-house.
Cleveland units in chemical plant and refinery environments are exposed to corrosive atmospheres that degrade housing, gear surfaces, and bearing components over time — requiring full decontamination and restoration.
Abnormal vibration signatures in Cleveland gearboxes indicate worn gear mesh, loose assemblies, or damaged bearings — all diagnosed and corrected as part of our full documented rebuild process.
Every Cleveland gearbox receives the same disciplined documented rebuild — from initial teardown through final load test and 24-month warranty certification.
We arrange no-cost freight pickup anywhere in the US. Your Cleveland gearbox is logged, assigned to a specialist technician, and full disassembly begins the same day it arrives at our facility.
All components are cleaned in our industrial parts washer. Every gear, shaft, bearing journal, and housing bore is individually measured and documented against Cleveland OEM tolerances for a precise repair scope.
We identify and document the exact failure cause — ensuring the same failure mode doesn't recur when the repaired Cleveland unit returns to your production line or plant equipment.
Worn Cleveland gears and shafts are manufactured on-site to OEM hardness and dimensional specifications. Precision boring and shaft repair are performed in our fully equipped machine shop for complete in-house control.
Reassembly uses Timken-certified bearings installed via liquid nitrogen thermal process. All new seals, gaskets, and a high-temp polymer housing coating complete the rebuild to better-than-OEM standard.
Every rebuilt Cleveland gearbox completes a full six-hour load test monitoring vibration, temperature, and leak-tightness before shipping with our 24-month production warranty.
We manufacture Cleveland gears on-site. No OEM backorders — just precision parts cut to spec and ready in days.
Every Cleveland 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 U.S. We handle all logistics from door to door.
A Specialty Gear Drives rebuild costs a fraction of sourcing a new Cleveland unit, with equal or better reliability.
Our technicians hold the same certifications required by OEM service centers — ensuring every repair meets the highest industry standards.
We maintain blueprints for every Cleveland 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 Cleveland repair turnaround.
Call us and our repair coordinators — experienced former field technicians— can often diagnose your Cleveland gearbox failure over the phone before the unit even ships.
