Made of high-strength magnetic material with lasting adsorption force, it firmly captures metal abrasive particles and fine iron impurities in lubricant. It effectively purifies lubricating oil and prevents hard particles from scratching gears, bearings and other precision components. Compact in size without occupying extra space, it is easy to install, oil resistant and demagnetization proof. It reduces abnormal wear of internal parts and extends the service life of core gearbox components.
