Rulmeca 1000HD Motorized Pulley

Models & Specifications
- 1000HD: 40.16″ diameter, 220–330 HP, belt speeds 600–1,320 fpm, face widths from 55.12″.
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.
- Heavy-Duty Construction: Engineered-class build for continuous high-tonnage service.
- VFD Compatible: Pairs with variable frequency drives for soft starts and speed control.
