Inner Diameter: 65 mm
Outer Diameter: 97 mm
Width / Thickness: 7.5 mm
Model / Type: BAFSL1SF
Material: Viton (FKM) / Fluororubber
Color: Brown / Dark Rubber + Metallic / Elastomer support
Seal Type: Radial / Rotary Shaft Oil Seal
Spring Loaded: Yes, includes internal spring for lip preload
Suitable Media: Hydraulic oils, mineral oils, grease
Temperature Resistance: Approximately −20°C to +200°C (typical for Viton materials)
Chemical Resistance: Excellent resistance to oils, fuels, many industrial chemicals
Wear Resistance: High, due to spring-supported lip design
Aging Resistance: Good; resistant to ozone, UV, oxidation
Operating Environment: Hydraulic pumps (e.g. Sauer PV23), motors, heavy machinery
Installation: Press-fit / cartridge style fit into housing bore
Lip Design: Single lip with spring for reliable sealing against shaft
Backing / Skeleton Structure: Metal or rigid support behind the rubber element
Oil Resistance: Very good
Dimensional Tolerance: Precision manufactured to match specified size
OEM / Part Number: 1905006
Application / Fitment: Specifically used in Sauer PV23 pumps
Label / Marking: “65×97×7.5”, “BAFSL1SF”, “1905006” visible on packaging or product
Origin: Hebei, China
Quality Standard: Complies with ISO / industrial sealing product standards
Packaging: Individual box + outer carton
Weight: Relatively light (approx dozens of grams) depending on structure
Pressure Cycling Durability: Designed to withstand pressure fluctuations
Seal Contact Surface Finish: Smooth finish for minimizing wear and leakage
Compatible Shaft Material: Steel or alloy steel, polished shaft surfaces
Corrosion Resistance: Metal parts likely have anti-corrosion coating or treatment
Ambient Temperature Range: −20°C to +200°C (approx)
Sealing Pressure Range: Medium to high hydraulic pressure applications
Maintenance: Replacement needed when lip is worn, rather than repair
Service Life: Long under proper working conditions
Dust / Contaminant Protection: Single lip—primary function is sealing fluids; not ideal for heavy dust without additional dust lips
Installation Space Requirement: Housing bore must fit outer diameter and enough depth for 7.5 mm lip width
Friction Coefficient: Designed to minimize friction between lip and shaft
Speed Limit (Shaft RPM): Suitable for moderate shaft speeds typical in hydraulic pumps; speed limits determined by lip heat build-up and lubrication
