Product Features

399.61 mm Assembled OD & Micro-Lapped Metal Seal Faces: Precision-engineered with an assembled outer diameter of 399.61 mm, featuring two high-hardness alloy steel/cast iron seal rings with micro-lapped contact faces. Forms a microscopic hydrodynamic oil film between the spinning metal faces to maintain an absolute oil-tight seal under high-torque rotations. 

Dual-Cone Elastomeric Toric Rings & Alignment Flexibility: Equipped with dual-cone elastomeric toric rings (NBR/FKM/Silicone) that seat against the housing ramp. Provides uniform axial load and flexibility to absorb shaft deflection, axial play, and heavy structural misalignments without sacrificing sealing performance. 

HRC 58-68 Micro-Hardness & Severe Duty Tolerance: Seal rings are heat-treated to an exceptional micro-hardness of 58–68 HRC, ensuring maximum wear resistance against ultra-abrasive rock dust and slurry. Designed to endure intense operating thermal dissipation for a working lifetime of 5,000–8,000 hours.
