Conveyor Systems:
- Role: The cylindrical roller design supports heavy radial loads, ensuring smooth operation of the conveyor without excessive wear.
Pumps:
- Role: Provides reliable radial load support, allowing the pump’s rotor or impeller to rotate with minimal friction, and it also handles thermal expansion.
Gearboxes:
- Role: Plays an essential part in carrying radial loads within the gearbox, ensuring smooth power transmission between gears, while maintaining structural integrity under load.
Fans and Blowers:
- Role: Supports the shafts in high-speed fans or blowers, ensuring smooth rotation and durability under fluctuating loads.
Role in Machines:
In these machines, the NU 310 ECM/C3VL0241 primarily:
