DescriptionMaterial:Elastomer NBR.
Brace ring and tension spring steel.Version:Shore ~70, black.Note:Rotary shaft lip seals are ready-to-install seals for sealing rotating shafts. They are made from an elastomer outer sleeve and an internal bracing shim. The tension spring ensures increased pressure of the lip against the shaft and supports static sealing.
Form A: DIN 3760 (ISO 6194/1) version, smooth OD.
Form AS: DIN 3760 (ISO 6194/0) version, smooth OD with extra dust lip to protect from external dirt.
The material NBR has a high wear resistance and is resistant to motor fuels, oil, hydraulic oil and lubricating grease.
Operating limits:
Circumferential speed (m/s): ≤12
Pressure (MPa/bar): ≤0.05/0.5 (rotary shaft lip seals are generally meant for unpressurised operation).
Temperature range:-40 °C to +100 °C.Tolerances:Housing:
Tolerance H8 is recommended.
Surface finish Ra 1.6 to 6.3 µm.
Shaft:
Tolerance h11 is recommended.
Surface finish Ra 0.2 to 0.8 µm.
The shaft hardness should be at least 45 HRC.Special features: DownloadHere is all the information as a PDF datasheet:
