AG 12 X 32 X 5 NBR

Shaft
Shaft tolerance: h11
Surface roughness: Ra 0,3 - 0,5 μm plunge grinding
Surface hardness: 40 - 60 HRC

Housing
Tolerance: H8
Installation chamfer: max. 10°, chamfer 2 mm and max. 1/4 of the seal width.

Operating conditions
Pressure: ≤0,5 bar
Temperature: -35°C...+100°C

Surface speed:
≤12 m/s, maximum surface speed when oil lubrication is good and heat created by friction leads out of sealing lip.
≤30 m/s, type AS-PL ...NBR/T (PTFE coated sealing lip)

Maximum surface speed must be reduced approx:
- 1/3 if good grease lubrication
- 1/5 if seal with dust lip
- 1/3 if sealing lip without spring
- 1/2 if two sealing lips with spring (e.g. R-duo)

Material: Nitrile rubber
