Nice Robus 600 Worm Gear

Nice Robus 600 Worm Gear (Infinity Gear)

The Nice Robus 600 worm gear is a critical power transmission element in sliding gate automation systems that transfers the motor's rotary motion to the gate arm. Fully compatible with the Robus 600 and Robus 600HS models, this part forms the drive side of the worm screw — worm gear pair within the motor's reduction mechanism. Manufactured from high-strength metal alloy by design, the gear is dimensioned to withstand the dynamic loads of the Robus series, which can handle gate weights of up to 600 kg. Under prolonged use, insufficient lubrication, or overload conditions, wear, breakage, or play may occur on the gear teeth; in such cases the gate moves slowly, produces abnormal noise, or stops moving altogether — these symptoms are direct indicators that the worm gear needs to be replaced.

Replacing this spare part is rated DIFFICULT. To access the worm gear, the motor's chassis cover must be removed, the reduction group components must be disassembled in a specific sequence, and the new gear must be seated precisely on the shaft axis. After installation, correct adjustment of the gear backlash and re-lubrication with appropriate grease are mandatory; incorrect installation or insufficient lubrication may cause permanent mechanical damage to the reduction group. For this reason, it is strongly recommended that the replacement be performed by an authorized service technician or a specialist experienced in automation systems.

This part is an original (OEM) spare part manufactured by Nice S.p.A. Italy-based Nice S.p.A. has been a globally recognized manufacturer in the field of gate, door, and sun shading automation since 1993. The use of an original part directly affects the preservation of reduction group tolerances, the extension of motor service life, and the system's return to its original torque and speed performance. Since dimensional deviations or material quality differences found in aftermarket gears can quickly lead to new failures, this original part with stock code PMD1088R02.4610 is the safest investment choice.
