At Specialty Gear Drives, we specialize in the emergency repair, rebuild, and in-house manufacturing of Weiler gearboxes — including headstock drives, spindle gearboxes, feed gearboxes, and apron drives across all Weiler lathe and machine tool series. Our Timken-certified technicians restore your Weiler unit to better-than-OEM condition with the fastest turnaround in the industry.
All Fields Must Be Filled Out
Multi-speed headstock gearboxes powering Weiler spindle systems. Critical to precision turning accuracy — rebuilt to exact gear mesh and preload specifications.
Feed gearbox and apron drive assemblies controlling longitudinal and cross-feed rates on Weiler engine and cycle-controlled lathes. Precision-critical for threading and facing operations.
Spindle drive gearboxes and back-gear assemblies for Weiler toolroom and CNC lathe platforms — rebuilt to maintain the tight geometric accuracy Weiler machines are known for.
Primus, Praktikant, Condor, Commodor, DA series, V-Series, and all legacy Weiler models fully supported — including machines no longer in OEM production.
When Every Hour of Downtime Costs You
Weiler precision lathes and machine tools are engineered in Germany to deliver decades of reliable service across aerospace, energy, defense, and general metalworking applications. But when a Weiler headstock gearbox or feed drive fails, your entire machining capability stops — and replacement lead times from overseas OEM channels can stretch for weeks or months.
Specialty Gear Drives provides the fastest certified repair path for any Weiler gearbox. We disassemble, inspect, and manufacture replacement components on-site to exact OEM tolerances — restoring the geometric precision and spindle accuracy that Weiler machines are built on, at a fraction of the cost of a new unit or factory service.
When a Weiler gear or precision component is beyond repair, we produce a new one on-site — matching OEM Rockwell and Brinell hardness ratings across all profiles and machine series, including legacy models and discontinued parts.
Even Weiler’s German-engineered precision drives encounter specific failure modes after years of continuous industrial service. Our diagnostics team identifies the exact root cause before any repair work begins.
Weiler headstock change gears and speed-range clusters develop surface fatigue and tooth wear under sustained high-RPM spindle loads. Even minor gear wear degrades the surface finish and dimensional accuracy the machine is rated for.
Precision spindle and gearbox bearings in Weiler machines are built to tight tolerances — when they fail, vibration increases and geometric accuracy is immediately compromised. We replace all bearings with Timken-certified equivalents using our liquid nitrogen thermal installation process.
Weiler feed gearboxes control thread pitch and feed rate selection. Worn or stripped Norton gearbox components cause incorrect feed ratios, damaged threads, and loss of precision control across the entire slide system.
Degraded input and output shaft seals allow lubricant to escape and contamination to enter — accelerating internal wear throughout the headstock and feed gearbox assemblies. All seals and gaskets are replaced as standard on every Weiler rebuild.
Weiler back-gear mechanisms used for low-speed, high-torque turning operations experience accelerated wear when engaged under load without proper lubrication. We restore or manufacture all back-gear components to OEM engagement and clearance specifications.
Bearing migration under operational shock loads causes housing bore wear in Weiler gearbox castings — leading to misalignment and compounding gear damage. Precision line-boring restores all critical bore diameters to factory specification.
Sustained heavy-cut operations or inadequate coolant cycles push Weiler gearbox components beyond thermal design limits. We restore heat-damaged gears and shafts and apply a high-temp polymer housing coating to reduce future heat buildup.
Abnormal vibration or noise in a Weiler lathe is a direct threat to part quality and machine geometry. Our full rebuild process traces every contributing factor — worn gears, loose assemblies, misaligned shafts — and corrects them before load testing.
Every Weiler gearbox receives our full six-step rebuild process — including specialized procedures for headstock change-gear clusters, Norton feed gearboxes, and back-gear assemblies across all Weiler lathe series.
We arrange no-cost nationwide freight pickup. Your Weiler gearbox arrives and is immediately logged, assigned to a specialist technician, and full disassembly begins the same day — no queue wait.
All components — change gears, feed gears, spindle bearings, shafts, selectors, and housings — are cleaned in our industrial parts washer and individually measured against OEM tolerances and Weiler's original accuracy specifications.
We identify and document exactly why the Weiler gearbox failed — overloading, lubrication breakdown, operator error, or wear-related fatigue — so the same failure mode doesn't recur once the machine returns to production.
Worn Weiler gears, shafts, selector forks, and precision components are manufactured on-site to OEM dimensional and hardness specifications — including legacy and discontinued series where original parts are no longer available.
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 and backlash set to Weiler factory specifications.
Every rebuilt Weiler gearbox runs a full six-hour load test monitoring vibration, temperature, and leak-tightness before certification with our 24-month production warranty — ensuring it meets the precision standards Weiler is known for.
We manufacture Weiler gears on-site. No OEM backorders — just precision parts cut to spec and ready in days.
Every Weiler 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 Weiler 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 Weiler 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 Weiler repair turnaround.
