Rulmeca 630 Series Motorized Pulleys
The 24.8″-diameter Rulmeca 630 series (M and H) steps into serious tonnage — overland and plant conveyors to 75 HP with the entire drive train sealed in an oil bath.
Models & Specifications
- 630M: 7.5–30 HP, belt speeds 150–760 fpm, face widths from 29.53″.
- 630H: 30–75 HP, belt speeds 240–960 fpm, face widths from 37.40″.
Key Features:
- Hermetically Sealed Drive: Motor, gearbox, and bearings are fully enclosed inside the pulley shell, protected and constantly lubricated by an internal oil bath — no exposure to dust, weather, or washdown.
- Safer by Design: Far fewer external moving parts than an exposed motor/gearbox drive, making guarding simpler and reducing injury risk.
- Compact & Lightweight: Typically 20–40% lighter than a comparable exposed drive arrangement — no external pillow block bearings, couplings, or guards.
- Minimal Maintenance: No routine greasing — seals at ~30,000 operating hours and oil changes at ~50,000 hours.
- Diamond-Pattern Lagging Standard: Black rubber lagging applied to suit horsepower and belt speed.
- VFD Compatible: Pairs with variable frequency drives for soft starts and speed control.
