DM216 Belt Conveyor Oil Cooling Motor Roller
The DM216 is a medium load belt conveyor motor roller with a 216 mm diameter, driven by a 3-phase AC motor at 400 V, 50 Hz, and rated from 0.37 kW to 5.44 kW. It features an oil immersion cooling system, a die-cast aluminum gear box, and a high alloy steel precision ground gear set for low noise operation. The roller is built for heavy single items and bulk material handling, with a steel tube and anti-slip screw thread on the face. It is sealed to IP66/67 at both shaft ends and comes pre-filled with oil for initial operation.

- Pre-filled with oil for immediate operation, with oil change recommended after 50,000 hours
- Available in multiple power ratings from 0.37 kW to 5.44 kW to match load and speed needs
- Steel tube with anti-slip screw thread improves belt grip and prevents slippage
Application Scenarios
- Heavy product conveyance in steel manufacturing or metal processing lines
- Bulk material handling in mining or aggregate processing where consistent torque is required
- Food manufacturing lines requiring a cleanable, non-marking surface with SUS304 tube option
- Supermarket cashier belt conveyors handling heavy or irregularly shaped packages
- Security inspection systems where reliable, low-noise operation is critical
Who It Is For
- Conveyor system integrators building medium load belt conveyors
- Industrial equipment builders requiring durable motor rollers for heavy-duty applications
- Food processing plant engineers needing washdown-compatible or food-grade materials
- Logistics automation contractors sourcing custom motor rollers for specialized lines
- Industrial distributors stocking motor rollers by power and diameter
Problems It Solves
- Overheating in long-running belt conveyors due to inadequate cooling
- Gear noise and premature wear from low precision gear sets in standard rollers
- Shaft seal failure in dusty or wet environments due to insufficient protection
- Belt slippage on the roller face due to lack of surface texture or grip
- Inconsistent performance when using non-standard or mismatched motor and gear combinations
Technical Features
- Oil immersion cooling system for sustained high-load operation
- Die-cast aluminum gear box with high alloy steel precision ground gears
- IP66/67 sealing at both shaft ends for dust and water resistance
- Anti-slip screw thread on the roller face to improve belt grip
- Pre-filled with oil before shipping, with oil change recommended after 50,000 hours
- Motor insulation class F for reliable performance under thermal stress
- 3-phase AC motor at 400 V, 50 Hz, with options for 50 Hz or 60 Hz operation
- Electrical chord length of 1.2 meters for standard connection routing
Materials
- Carbon steel tube with galvanization and anti-rust paint for general industrial use
- SUS304 stainless steel tube for food-grade or washdown environments
- Die-cast aluminum for the gear box to reduce weight and improve heat dissipation
- High alloy steel gears for high strength and low noise under load
- Oil for immersion cooling, with change recommended after 50,000 hours of operation
Quality Control
- Motor insulation class verified before assembly
- Gear mesh and rotation checked for smoothness and noise
- Sealing integrity tested under pressure to confirm IP66/67 rating
- Oil fill level confirmed before shipping
- Electrical chord length measured and verified
Customization Options
- Power rating selected from available options between 0.37 kW and 5.44 kW
- Tube material changed to SUS304 for food-grade or corrosive environments
- Speed and length customized to match client’s conveyor design
- Backstop can be added without affecting minimum roller length
- Non-standard designs made upon client request
Use Guide
- Select power rating based on required speed and load to avoid overloading the motor
- Ensure the conveyor belt tension does not exceed the roller’s radial load capacity
- Use SUS304 tube for food processing or washdown areas to meet hygiene standards
- Do not operate without oil; the roller is pre-filled but oil must be changed after 50,000 hours
- Mount horizontally to maintain proper oil distribution and gear lubrication
