Nice PPD1990.4540 Internal Plastic Gear (Compatible with Run 400HS / Run 1200HS / Run 1500 – Power Transfer Gear)

Nice PPD1990.4540 Internal Plastic Gear – Original Spare Part Compatible with Run 1200HS and Run 1500

Nice PPD1990.4540 is the original internal plastic gear that forms the heart of the reduction mechanism in Nice Run series sliding gate motors. This part is directly responsible for transferring the rotational movement produced by the motor shaft to the reduction group, enabling the gate to move in a controlled and smooth manner. Manufactured from high-strength engineering plastic, this gear is designed to maintain its shape and remain resistant to wear under prolonged operating conditions. Over time, mechanical fatigue, excessive load, or contact with foreign objects may cause breakage or wear on the gear teeth; in such cases, the motor runs but the gate does not move, or gate movement becomes irregular and noisy. The part is directly compatible with Nice Run 400HS, Nice Run 1200HS, and Nice Run 1500 models.

Replacing this spare part is of INTERMEDIATE difficulty level. Basic mechanical knowledge is required, as the motor housing must be opened, the old gear must be removed from the shafts and retaining components, and the new part must be installed in the correct axial alignment. If the gear is mounted with incorrect alignment, an unbalanced load may occur on the reduction group and may lead to additional failures; therefore, it is recommended to verify that the gear seating surfaces are clean and undamaged during installation.

Nice PPD1990.4540 is an original (OEM) spare part manufactured by Nice S.p.A. Italy-based Nice S.p.A. is one of Europe's leading manufacturers in the field of automatic gate and barrier systems, and this part is produced in accordance with the brand's own manufacturing quality standards and original design tolerances. The use of original parts directly affects the maintenance of motor performance within manufacturer specifications and the long-term reliability of the system.
