BABSL (OLIEKEERRING HD)

product

BABSL NBR

Rotary shaft seal equivalent to RP ­type in the HD design, pressurizable. It has a shorter, stronger, spring energised sealing lip. In addition, this model is available with a protective lip (BABSL) on the air side.

Description 

  • Product group: Rotary shaft seal
  • Design: BABSL = outer surface rubber-coated
  • Seal material: NBR 80
  • Colour: blue
  • Stiffening ring: non-alloy steel according to DIN EN 10139
  • Tension spring: non-alloy spring steel according to DIN EN 10270-1

Application

Sealing of rotating machine elements such as shafts, hubs and axles.

Function

The BABSL is a single-action rotary shaft seal for rotating or pivoting shafts with optional protective lip sealing action (BABSL) on the side facing away from the medium, against dirt accumulation from the outside.
The shorter, thicker, spring-energised sealing lip enables pressure application of up to 10 bar (depending on the rotational speed). The elastomer outer sheath provides good static sealing, good thermal expansion balance, e.g. in light-metal housing, better sealing with greater roughness and secure sealing for split housings as well as good static sealing with thin fluid or gaseous media.

Media

Good chemical resistance to many mineral oils and greases.

 

Operational application limits
Pressure ≤ 10 (Mpa/bar)
Temperature -40°C to +100°C
Peripheral speed ≤ 10 (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.
