Mother Roll Bearing Housing Set

If you’re looking to provide a rock-solid foundation for the heaviest part of your production line, our mother roll bearing housing sets are the industrial-strength anchors you need. We know that the mother roll (or jumbo roll) carries immense weight and creates massive centrifugal forces at high speeds, which is why these housings are precision-cast from heavy-duty SS 316 or high-grade cast iron to absorb vibration and prevent structural flexing.
These sets are engineered with internal spherical roller bearings that can handle significant axial and radial loads while automatically compensating for any slight shaft deflection that happens under the weight of a full roll. We’ve designed them with easy-access grease nipples and high-performance labyrinth seals to keep paper dust and moisture out, ensuring your bearings stay cool and lubricated even during 24/7 high-speed winding. It’s the best way to ensure your primary spool spins with zero “wobble,” protecting your drive motor and giving you a perfectly wound roll from the core to the final wrap.
