FANUC A06B-2115-B805 – Robot Two-Axis Speed Reducer | FANUC 10iA Series Platform
Engineering Background
The FANUC A06B-2115-B805 is a precision two-axis speed reducer assembly engineered for FANUC’s 10iA series industrial robot platform. Combining sub-assembly part numbers 2007-T299A660-4005-T080 and A97L-0218-0886/10iA, this unit delivers the torque multiplication and positional accuracy demanded by high-cycle automotive, electronics, and general manufacturing automation lines.
Product Positioning
Designed as a direct OEM-equivalent replacement for FANUC 10iA robot joint axes, this speed reducer maintains the original kinematic envelope, mounting interface, and gear ratio specifications — enabling drop-in installation without mechanical modification. Konmask.com supplies this component from verified industrial surplus and authorized distribution channels, supporting both emergency line-down recovery and planned preventive maintenance programs.

- Sealed Lubrication — Factory-packed grease eliminates field lubrication errors at installation
- Dual Sub-Assembly Traceability — Both internal part references (2007-T299A660 and A97L-0218-0886) documented for MRO records
- Broad Compatibility — Verified fit across FANUC 10iA robot variants; consult Konmask engineering for cross-reference confirmation
System Architecture & Signal Flow
In the FANUC 10iA kinematic chain, the A06B-2115-B805 speed reducer sits between the servo motor output shaft and the robot link structure. The servo amplifier (αi or βi series) drives the motor; the reducer multiplies torque while reducing output RPM to the joint’s operational range. The FANUC R-30iA / R-30iB controller closes the position loop via the motor’s built-in pulse coder — reducer mechanical integrity is therefore directly critical to servo loop stability and path accuracy. Degraded reducer backlash or bearing wear manifests as position error alarms (e.g., SRVO-023, SRVO-024) and increased following error on the affected axis.

Technical FAQ
Q: Is A06B-2115-B805 compatible with FANUC ARC Mate 100iA?
A: The 10iA platform shares mechanical architecture with several ARC Mate variants. Please confirm with our engineering team using your robot serial number before ordering.
Q: What grease type is specified for this reducer?
A: FANUC specifies Kyodo Yushi Molywhite RE No.00 or equivalent. The unit ships pre-packed; no additional grease is required at installation unless the unit has been opened for inspection.
Q: Can I use this reducer on J3 or J4 axes?
A: The A06B-2115-B805 is a two-axis assembly. Axis applicability depends on your specific robot configuration. Contact [email protected] with your robot model and axis map.
Q: What is the lead time for out-of-stock units?
A: Typical sourcing lead time is 2–4 weeks for non-stock units. Emergency procurement options may be available — contact us directly for urgent requirements.
Q: Do you provide installation services?
A: Konmask.com is a parts supplier. We recommend installation by a FANUC-certified service engineer. We can provide referrals to regional FANUC service partners upon request.
