Heavy duty,oversized bearings designed for longer L10 life in industrial applications.
·Dual-splash aluminum tank design ensures gear and bearing longevity.
·One piece integrated ductile iron rotorsand shafts, large shaft diameters, one piece high strength housing, and one piece end plates reduce torsion and
vibration.
· Housings are designed for horizontal or vertical mounting configurations.
·Multi-piston ring air and oil seals minimize maintenance costs and ensure delivery without oil and air crosscontamination.
·Viton lip oil seals with o-rings prevent oil leakage.
·Wearable shaft seeves prevent oi leakage past drive shaft and extends shaft life.
· The innovative Tri-Lobe rotor profile and advanced housing design reduce noise and vibration.
