KUKA KR 210 / KR 240 / ZH 210-240 Series: Comprehensive Gearbox Range and Technical Overview

The KUKA KR 210, KR 240, and ZH 210-240 series represent a core segment of KUKA's heavy-payload industrial robot lineup, deployed extensively across global heavy industry sectors including automotive body-in-white assembly, chemical plant material handling, nuclear facility maintenance robotics, and refinery pipeline welding automation. The gearbox assembly referenced by part number 00-106-447 is a precision-machined axis gearbox unit integral to the mechanical drive train of these robot models, governing torque transmission at the primary articulation axes. These robots carry rated payloads of 210–240 kg and are engineered for high-cycle, high-load environments where gearbox integrity is a direct determinant of system uptime. Installed base across petrochemical, steel, and heavy fabrication facilities makes lifecycle parts availability a critical operational concern.

The Evolution of KR 210 / KR 240 / ZH 210-240 Architecture

KUKA's KR 200-series heavy-payload robots were introduced in the late 1990s under the KR C1 and KR C2 controller generations. The KR 210 and KR 240 designations reflect maximum payload capacity in kilograms, with the ZH 210-240 denoting the extended-arm (Zentrum-Hoch) variant optimized for overhead and shelf-mounted installation configurations. Early production units used RV-type cycloidal gearboxes at axes A1–A3 and harmonic drive units at A4–A6. Subsequent revisions under the KR C2 ed05 and KR C4 controller platforms introduced revised gear ratios and updated sealing standards to address lubricant migration issues identified in high-temperature foundry deployments. The KR 240-2 and KR 210-2 second-generation variants introduced a redesigned wrist assembly with improved backlash specifications. As of 2026, the KR 210 and KR 240 series are in the mature/end-of-production phase; KUKA's current equivalent platform is the KR QUANTEC series (KR 210 R2700 EXTRA, KR 240 R2900 ULTRA). Long-term maintenance support for installed KR 210/240 units is therefore dependent on third-party spare parts distributors and certified refurbishment providers.

Sourcing Hard-to-Find & Obsolete KR 210 / KR 240 / ZH 210-240 Parts

With the KR 210 and KR 240 series having entered end-of-production status, OEM spare parts availability through standard distribution channels is progressively constrained. DriveKNMS maintains a dedicated inventory program for lifecycle-extended support of this series. Stock is sourced through controlled dismantlement of decommissioned units, certified refurbishment of returned assemblies, and direct procurement from verified secondary-market suppliers. All gearbox units including 00-106-447 and related axis assemblies are held in climate-controlled storage to prevent lubricant degradation and bearing corrosion. For facilities operating KR 210/240 robots beyond OEM support windows, DriveKNMS provides multi-year supply agreements covering critical wear items across the full mechanical and electrical BOM.

Quality Control for the KR 210 / KR 240 / ZH 210-240 Range

Gearbox assemblies for the KR 210/240 series undergo a structured inspection protocol prior to dispatch. Each unit is disassembled to component level for bearing race inspection, gear tooth profile measurement, and seal integrity verification. Reassembled units are filled with manufacturer-specified lubricant (Optigear Synthetic RO 150 or equivalent) and run on a dedicated break-in test rig simulating rated load cycles. Backlash is measured at the output flange and must fall within OEM tolerance bands before the unit is cleared. Electronic modules including servo drives, RDC boards, and power supplies are bench-tested under load using KR C2-compatible test fixtures, with all axis channels verified for current loop response and encoder signal integrity. Each dispatched part is issued a test report and assigned a traceability reference number.
