Rotor locating bearing

Product Introduction

JOJI rotor positioning bearings are custom-designed units with optimized mechanical integration between the magnetic pulse ring and the bearing. This integrated unit:

Can be used with nearly all bearing types
Permits high speeds and high temperatures
Generates strong magnetic pulses related to the rotor's angular position
Can transmit magnetic fields in axial or radial directions on straight shafts or at shaft ends
The high magnetic field strength makes it highly reliable even under harsh operating conditions
