Example of use
BA SL SF
With axial dust lip
Against moderate dirt ingress;
axial dust lip in conjunction with a
dirt excluder element (Labyrinth)
Transmissions
Axles: pinion seal
Special types for soiled media to be sealed
MSS 2 (Modular Sealing Solution)
Inner seal made from nonwowen material
Nonwowen material sealing disc
prevents contact of the sealing edge with
particles in the contaminated media
Drives in industrial gearboxes
Types for separation of two media
BA DUO
Two sealing lips
For the separation of two media;
narrow design; can also be used for
moderate dirt ingress from the outside
Circumferential speed < 5 m/sec
Grease filling between the
sealing lips max. 40 %
Encoder
Radial encoder | Axial encoder
Metal – rubber parts with
magnetizable rubber layer
Magnetization of accurate north and
south poles allows a high-precision shaft
speed measurement with a digital sensor
Applications that require a
rotation speed measurement:
wheel hub bearing gearbox,
crankshaft, others
