Shaft Seals Oil Seal 50 x 68 x 8 mm B2PT PTFE Single Lip, Stainless Steel High-Pressure Hydraulic Seals, for Industrial Pumps, Screw Air Compressor Rotary Shaft 50-68-8

Marking Dimensions: 50×68×8 mm or 50*68*8 mm Installation Dimensions: 50mm (shaft diameter) x 68mm (bore diameter) x 8mm (width). Stainless Steel Cased Oil Seal, Rotary Shaft Seal. Applications: Compressor seals, pump & valve seals, chemical equipment seals, high-pressure shaft seals. PTFE (Polytetrafluoroethylene) Material Properties & Advantages Wear Resistance: Extremely low friction coefficient (0.02), 1/40 that of rubber. Thermal Stability: Crack temperature exceeds 400°C; operational range: -60°C to +350°C. Self-Lubricating: PTFE surface exhibits exceptional self-lubrication, resisting adhesion from almost all viscous substances. Superior Performance: Ideal for harsh fluids and environments where rubber seals fail. Pressure & Speed Ratings Single Lip: 1.5MPa (≤30m/s) Double Lip: 3.0MPa (≤30m/s) Triple Lip: 4.0MPa (≤30m/s) [Can operate at 40m/s with reduced pressure tolerance; lower speeds increase pressure capacity.] DMHUI is a China-based oil seal manufacturer with 18 years of expertise, delivering high-quality products.
