Bonfiglioli RAN Series
Bonfiglioli RAN Series is a high-performance single-stage helical bevel gearmotor, specialized in right-angle transmission applications. Engineered by the Italian power transmission expert, this series is renowned for its compact structure, easy installation, and maintenance-free design, serving as a reliable core component in synchronous control systems and screw jacks worldwide.
The series features a precise single-stage transmission structure, with a standard 1:1 speed ratio and optional accurate ratio variants to meet customized synchronous control needs. Adopting high-quality helical bevel gears with carburizing and quenching treatment (HRC58-62), it ensures smooth meshing, low noise emission, and strong wear resistance, delivering stable power output even in long-term continuous operation.
Designed for versatility, the RAN Series offers multiple shaft configurations, adapting to diverse installation requirements in limited spaces. Its robust cast iron housing provides excellent torsional rigidity and impact resistance, with standard IP54/IP55 protection rating to withstand dust and moderate moisture, suitable for general industrial environments and partial harsh scenarios.
With almost no maintenance requirements, the series significantly reduces operational costs for users. It seamlessly integrates with various motors and control systems, widely applied in synchronous control devices, screw jacks, light-duty conveyors, and precision mechanical equipment. Embodying Bonfiglioli’s engineering excellence, it balances reliability, simplicity, and cost-effectiveness for light to medium-duty right-angle transmission demands.
Bonfiglioli RAN Series (Right‑Angle Bevel Gear Units) Specifications
Note: RAN Series is a compact right‑angle bevel gear unit line with multiple shaft arrangements, prefilled oil, and exact ratio options (including 1:1). Ideal for synchronized drives, screw jacks, and positioning systems. Supports IEC asynchronous (BN/BE/BX), reluctance (BSR), and single‑phase (BS) motors. Weights are for standard B3/B5 units (excluding brakes/encoders)Bonfiglioli.
