All Fields Must Be Filled Out

Standard Series

Tandler's flagship Klingelnberg ground spiral bevel gearboxes — available in 9 frame sizes and 11 ratios. Six-sided universal mounting, low backlash of 5–6 arc min, and taper roller bearing options for high radial load.

ServoFoxx

The SKP2FS, PSK2FS, and FS2 servo gearhead series — two-stage and single-stage spiral bevel designs for maximum torque density, low backlash, and dual-output servo applications in motion control systems.

PowerMaster HL

Heavy-duty right-angle helical bevel gearboxes engineered for high-power line-shaft and industrial drive applications requiring maximum torque output in compact configurations.

Sesame & WV Series

Right-angle planetary spiral bevel gearheads with helical precision planet gears, and the reinforced WV line-shaft gearboxes designed for tapping torque from a main drive shaft at multiple intervals along a production line.

When Every Hour of Downtime Costs You

Is Your Tandler Gearbox Down?

Tandler spiral bevel gearboxes — engineered and manufactured in Germany — represent the gold standard in precision right-angle power transmission. With Klingelnberg-ground gears, six-sided universal mounting, and standard backlash of just 5–6 arc minutes, Tandler units are trusted in robotics, CNC machinery, aerospace systems, printing lines, and high-speed automated production environments where motion accuracy is non-negotiable.

When a Tandler gearbox develops increased backlash, bearing noise, or seal failure, precision is lost immediately — and so is product quality. Specialty Gear Drives provides the fastest certified Tandler repair path available, with in-house spiral bevel gear manufacturing capability to restore OEM tooth geometry, hardness, and contact pattern on every component we touch.

Root Cause Analysis

Common Tandler Gearbox Gearbox Failures

Tandler precision spiral bevel gearboxes operate at tight backlash tolerances — even minor wear degrades the motion accuracy they are specified for. Our diagnostics team identifies every root cause before any repair work begins.

Spiral Bevel Gear Wear

Tandler Klingelnberg-ground spiral bevel gears develop surface fatigue and tooth wear under sustained high-speed, high-cycle loads in servo and motion control applications. Any wear beyond tolerance immediately degrades backlash and transmission accuracy.

Bearing Failure

Tandler gearboxes use precision ball and taper roller bearings selected for smooth, low-vibration operation. Bearing failure introduces play, vibration, and noise that directly compromise the tight angular accuracy Tandler drives are rated for. All bearings replaced with Timken-certified equivalents.

Seal Failure & Oil Loss

Input and output shaft seals in Tandler gearboxes degrade under thermal cycling and high-speed operation, allowing lubricant loss and contamination ingress. All seals and gaskets are replaced as standard in every Tandler rebuild.

Backlash Growth

Accumulated gear and bearing wear in Tandler units causes backlash to grow beyond the 5–6 arc-minute OEM specification — immediately affecting CNC accuracy, print registration, and servo positioning precision. We restore all preloads and contact patterns to OEM tolerance.

Shaft & Bore Wear

Fretting corrosion and dimensional wear on Tandler input and output shafts and housing bores — caused by improper mounting or sustained vibration — requires precision reconditioning or new component manufacture to OEM specification.

Housing Bore Deterioration

Bearing migration under shock loads causes housing bore wear in Tandler gearbox castings, degrading gear mesh geometry. Precision line-boring restores all critical bore diameters to factory specification.

Thermal Damage

High-cycle servo and motion control applications push Tandler gearboxes beyond thermal limits when lubrication degrades. We restore all heat-affected components and apply thermal-protective housing coatings to prevent recurrence.

Noise & Vibration

Abnormal noise or vibration in a Tandler unit signals deteriorating gear mesh, worn bearings, or structural looseness — all of which worsen rapidly at high cycle rates. Our full diagnostic teardown addresses every contributing factor.

Our Proven Method

The Specialty Gear Drives Repair Process

Every Tandler gearbox receives our complete six-step rebuild — including specialized procedures for Klingelnberg spiral bevel gear sets, ServoFoxx servo stages, and PowerMaster HL configurations across all series and frame sizes.

Free Pickup & Intake

We arrange no-cost nationwide freight pickup. Your Tandler gearbox arrives and is immediately logged, assigned to a precision specialist, and full disassembly begins the same day — no wait queue, no delays.

Industrial Cleaning & Inspection

All components — spiral bevel gears, planet gear sets, shafts, bearings, and housings — are cleaned and individually measured against Tandler OEM tolerances, including backlash, contact pattern, and bearing preload specifications.

Root Cause Documentation

We identify and document exactly why the Tandler unit failed — fatigue wear, contamination, improper preload, or shock overload — so the root cause is corrected and doesn't recur once the gearbox returns to precision service.

In-House Component Manufacturing

Worn Tandler spiral bevel gears, shafts, and precision components are manufactured on-site to OEM dimensional and hardness specifications — including Klingelnberg tooth profiles for discontinued or legacy Tandler series.

Rebuild & Bearing Upgrade

Reassembly uses Timken-certified bearings installed via liquid nitrogen thermal process — never pressed. All new seals, gaskets, and housing coating complete the rebuild with all backlash and preload settings restored to Tandler OEM specification.

6-Hour Load Test & Certification

Every rebuilt Tandler gearbox runs a full six-hour load test monitoring vibration, temperature, backlash, and leak-tightness before certification under our 24-month production warranty.
