B2 (OLIEKEERRING)

product

B2 NBR

Rotary shaft seal in standard design with a metal outer surface, a metal insert and a spring-energised sealing lip made of elastomer. In addition, the standard model can also delivered with a dust lip (B2SL) on the air side.

Description 

  • Product group: Rotary shaft seal
  • Design: B2 = outer surface metal and metal inner ring
  • Seal material: NBR 70
  • Colour: black / steel housing
  • Stiffening ring: non-alloy steel according to DIN EN 10139
  • Tension spring: non-alloy spring steel according to DIN EN 10270-1

Application

Heavy engineering, agricultural and forestry machinery, wind energy converters and rolling mills. As a result of its greater rigidity the B2/B2SL is particularly suitable for larger dimensions as well as difficult installation conditions and severe operating conditions

Function

The B2 is a single acting rotary shaft seal for rotating shafts with the optional dust lip sealing action (B2SL) on the side facing away from the medium, against contamination from outside. The metaleninsertring inside indicates the oil seal more rigidity and the metal outer casing tight and accurate fit. Guarantees a high static seal on the outside, improved surface treatment of the bore is required or an additional layer of paint has to be applied to the metallic outer casing.

Media

Good chemical resistance to many mineral oils and greases.

Operational application limits
Pressure ≤ 0.05/0.5 (Mpa/bar)
Temperature -40°C to +100°C
Peripheral speed ≤ 12 (m/s)

Installation

Suitable tools should be used for installation. It is recommended that the installation housing is designed to provide the rotary shaft seal with axial support.
