Product description

nnnn

The standard Simmerring BA...U...SL as basic module combined

nnnn

with an inner buffer seal with sine wave-shaped sealing lip as

nnnn

one-piece solution, e.g., for drive technology applications.

nnnn

A proven type with high resistance to soiling and metal abrasion

nnnn

in the oil chamber.

nnnn

Product advantages

nnnn

■ Broad range of applications, for example in industrial gear-

nnnn

boxes

nnnn

■ Reliable sealing of the housing bore, even with increased

nnnn

roughness of the bore, thermal expansion and split housings,

nnnn

thus a sealing of low viscosity and gaseous media is also

nnnn

possible

nnnn

■ Very long service life and reliability, especially when subject

nnnn

to strong external dirt and/or contamination (metal abrasion,

nnnn

cast sand) of the lubricant

nnnn

■ Optimal for vertical unit application

nnnn

■ Very narrow axial design

nnnn

■ Reliable sealing of the housing bore etc.

nnnn

Product properties

nnnn

■ Outer casing: elastomer (smooth)

nnnn

■ Spring-loaded sealing lip and sealing lip with helix edge

nnnn

without spring

nnnn

■ Additional dust lip

nnnn

■ Modern sealing lip profile

nnnn

■ Friction-optimised primary seal lip 1 made from fluoro rubber

nnnn

75 FKM585

nnnn

■ Secondary seal lip with additional dust lip 2

nnnn

■ Grease filling with special lubricant Kluber Petamo
