76mm Heavy-Duty Motorized Roller 300W for 3000kg Loads - China Suppliers & Factory for Efficient Automation
Product Introduction
The 76mm Heavy-Duty Pallet Motorized Roller (MDR) is specifically engineered to meet the rigorous demands of industrial pallet handling and high-capacity belt conveyors. By integrating a high-performance 300W brushless DC motor and a durable multi-stage planetary gear system directly inside the roller tube, we eliminate the need for complex external mounting and drive chains. This "all-in-one" design ensures a clean, aesthetic look while providing a completely maintenance-free lifecycle.
Built for industrial strength, this series handles payloads of up to 3000kg. A key advantage is its dual-sprocket configuration, which enables a single motorized roller to power up to 30 secondary rollers simultaneously. This high-torque capability significantly reduces hardware costs and simplifies the electrical architecture of your conveyor line.
To support modern smart warehousing, these rollers are compatible with diverse communication protocols, including RS485, CANopen, and standard I/O control. When paired with intelligent drive cards, the system delivers precise speed regulation (1.5m/min to 132m/min) and smooth acceleration/deceleration. This prevents mechanical shock during frequent start-stop cycles, protecting both your goods and the conveyor structure.
We offer extensive customization to fit your specific environment. Choose from galvanized carbon steel, SUS304 stainless steel, or optional rubber lagging for increased friction. Surface treatments such as knurling or crowning are also available to ensure optimal belt tracking or pallet grip.

Frequently Asked Questions
The 76mm MDR is engineered to handle a maximum load capacity of up to 3000kg (3 tons), making it well-suited for heavy industrial pallet handling and high-capacity conveyor applications.
Thanks to its dual-sprocket configuration and high-torque output, a single 76mm motorized roller can simultaneously drive up to 30 secondary (slave) rollers, significantly reducing the number of motors required and lowering overall system costs.
The 76mm MDR supports RS485, CANopen, and standard I/O control protocols. This broad compatibility makes it easy to integrate into Industry 4.0 smart warehouse management systems and automated conveyor lines.
The roller is available in DC 24V and DC 48V configurations. When paired with an intelligent drive card, it offers precise speed regulation across a wide range of 1.5m/min to 132m/min, with smooth acceleration and deceleration to prevent mechanical shock.
We offer a range of customization options including shell materials (galvanized carbon steel or SUS304 stainless steel), surface treatments (knurling, crowning), and optional rubber lagging. These options allow the roller to be tailored for specific friction, grip, belt tracking, or corrosion-resistance requirements.
No. The fully integrated design — with the brushless DC motor and multi-stage planetary gear system enclosed inside the roller tube — eliminates the need for external drive chains or complex mounting hardware. This sealed construction provides a completely maintenance-free lifecycle under normal operating conditions.
