At Specialty Gear Drives, we specialize in the emergency repair, rebuild, and in-house manufacturing of Western Gear gearboxes — including parallel shaft, right-angle, and vertical aerator drives used across mining, steel mill, aerospace, offshore, pulp & paper, and maritime operations. Timken-certified. 24-month warranty. Free pickup nationwide.
All Fields Must Be Filled Out
Western Gear's parallel shaft reducers deliver high torque output across single, double, and triple reduction configurations — the backbone of heavy material handling in mining and conveyor applications worldwide.
Western right-angle reducers engineered for ski lifts, large antenna drives, steel mill pinion stands, ore conveyors, and manned centrifuge test platforms — rebuilt to full OEM specification and load rating.
Western Gear vertical aerator drives used in municipal sewage treatment and wastewater processing facilities — continuous-duty units requiring precision torque management and zero-downtime rebuild standards
Western Gear marine gearboxes deployed in offshore operations, maritime propulsion, and rescue vessel generator drives — rebuilt to withstand the corrosive and high-shock environments of offshore industrial service.
When Every Hour of Downtime Costs You
Western Gear Corporation built a legacy of industrial drive engineering that powered some of the world’s most demanding applications — from massive ore conveyors and steel mill pinion stands to offshore generator drives and municipal aerators. Acquired by Philadelphia Gear and now part of the Timken family of brands, Western Gear products are found in critical operations across virtually every heavy industrial sector.
When a Western Gear drive fails, the downtime is immediate and costly. Specialty Gear Drives offers the fastest certified Western Gear rebuild path available — with in-house manufacturing capability to produce exact OEM-spec replacements for gears, pinions, and shafts, including legacy Western Gear configurations no longer stocked through standard distribution channels.
When a Western Gear component is beyond repair, we produce a new one on-site — matching OEM Rockwell and Brinell hardness ratings across all profiles and reduction configurations, including legacy Western Gear Corporation designs no longer available through standard channels.
Western Gear drives are engineered for extreme industrial duty — but decades of continuous service in mining, steel mill, and offshore environments eventually demands expert repair intervention. Our diagnostics team identifies the exact root cause before any repair begins.
Western Gear's high-torque parallel shaft and right-angle reducers develop surface pitting, spalling, and tooth fatigue under sustained shock loading in mining and steel mill applications. We manufacture replacement gear sets on-site to exact OEM profile and hardness specifications.
Western Gear gearboxes rely on high-capacity roller bearings throughout their reduction stages. Bearing failure under overload or lubricant contamination triggers rapid cascading damage. We replace all bearings with Timken-certified equivalents using liquid nitrogen thermal installation.
Degraded shaft seals in Western Gear drives allow oil loss and contaminant ingress — the leading cause of accelerated internal wear in continuous-duty mining and aerator applications. All seals and gaskets are replaced as standard in every Western Gear rebuild.
High-shock loads from ore conveyor start-stops and steel mill reversal cycles cause keyway deterioration and fretting corrosion on Western Gear shafts and pinions. Components beyond reconditioning are manufactured new to OEM hardness and dimensional specification.
Bearing migration under high radial loads causes Western Gear housing bore wear — resulting in misalignment that compounds internal deterioration across all reduction stages. Precision line-boring restores all critical bore diameters to OEM specification.
Western Gear marine and offshore drives are exposed to salt air, humidity, and chemical contamination that accelerates corrosion of housing, shafts, and internal components. Full strip-down, corrosion treatment, and protective coating restoration is included in every marine rebuild.
Continuous-duty operation in mining conveyors and steel mills pushes Western Gear drives beyond thermal limits when lubrication degrades. We restore heat-damaged components and apply a high-temp polymer housing coating to reduce future thermal buildup.
Structural misalignment from worn mounts or improperly aligned shafts transmits destructive vibration into Western Gear gearbox internals. Our full rebuild process addresses every misalignment contributor before reassembly and load testing begins.
Every Western Gear gearbox receives our complete six-step rebuild process — including specialized procedures for high-torque parallel shaft units, right-angle aerator drives, and marine gearboxes across all Western Gear series and configurations.
We arrange no-cost nationwide freight pickup. Your Western Gear gearbox arrives and is immediately logged, assigned to a certified technician, and full disassembly begins the same day — no queue, no delays.
All components — gear sets, pinions, shafts, bearings, and housings — are cleaned in our industrial parts washer and individually measured against OEM tolerances across every Western Gear drive configuration we service.
We identify and document exactly why the Western Gear unit failed — shock overloading, lubricant contamination, seal failure, or fatigue wear — ensuring the root cause is addressed and the failure mode doesn't repeat after repair.
Worn Western Gear sets, pinions, and shafts are manufactured on-site to OEM dimensional and hardness specifications — including legacy and discontinued configurations where original replacement parts are no longer available through supply chains.
Reassembly uses Timken-certified bearings installed via liquid nitrogen thermal process — never pressed. All new seals, gaskets, and a high-temp polymer housing coating complete the rebuild with all preloads set to Western Gear OEM specifications.
Every rebuilt Western Gear gearbox runs a full six-hour load test monitoring vibration, temperature, and leak-tightness before certification under our 24-month production warranty — ensuring it returns to full heavy industrial-duty service.
We manufacture Western gears on-site. No OEM backorders — just precision parts cut to spec and ready in days.
Every Western 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 Western 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 Western 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 Western repair turnaround.
Call us and our repair coordinators — experienced former field technicians— can often diagnose your Western gearbox failure over the phone before the unit even ships.
