​Optimized PTFE sealing lip concept for high rotation speed, bi-directional spin, dry running, low friction and unique lifetime endurance.

Reduced bearing friction due to a reduced number of contact sealing lips 
Additional labyrinth seal for improved sealing performance 

Volume control on oil flow by cage (resin cage) - reduction of friction caused by agitation resistance
Optimized inner ring raceway crowning - reduction in viscous rolling resistance

EQTF (Extra Quality Tough Ball Bearings For Transmissions) are bearings developed with balls made of special steel characterized by better wear protection through case hardening (carbonitriding) the surface and by adding hard silicon nitride particles within the steel. But the secret of their success does not lie in just applying the technology to existing applications.
