The core advantages of the product
Military-grade protective performance
Made of the German formula fluoroelastomer (FKM), it has passed the extreme temperature test from -40°C to 220°C, and the tear strength has been increased by 60%, effectively preventing sediment, water vapor, and metal debris from entering the bearing system.
Innovative design of dynamic sealing
The triple sealing structure (main lip, dust lip, spring compensation system) achieves double protection:
Automatic radial pressure compensation technology to compensate for wear up to 0.3mm
360° rotating dynamic sealing, suitable for 20-80rpm speed scenarios
Extend the service life of the equipment
The measured data shows that the use of this seal can enable:
Caterpillar D6 Series dozer maintenance intervals extended to 2,000 hours
Komatsu PC200 excavator bearing failure rate was reduced by 43%
Typical application scenarios
Crawler construction machinery: bulldozer/excavator/paver travel system
Agricultural machinery: combine harvester drive wheels
Mining equipment: rock drilling trolley guide wheel sealing
