Rulmeca 400 Series Motorized Pulleys
The 15.75″-diameter Rulmeca 400 series (L, M, and H) drives mainline quarry, mining, and cement conveyors up to 20 HP — fully sealed against the most abrasive, dusty environments.
Models & Specifications
- 400L: 3–10 HP, belt speeds 192–760 fpm, face widths from 19.69″.
- 400M: 3–20 HP, belt speeds 76–760 fpm, face widths from 23.62″.

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.
