OS-B11

Description

Metal OD
Spring loaded sealing lip
Protective lip against entry of contamination from outside (dust, dirt,...)

Special features

Modern sealing lip design for high dynamic sealing action
Very firm and exact fit inside the housing due to metal-metal interference fit
Be careful when using the product in connection with light metal housings, housings with increased surface roughness and applications with overpressure: Apply sealing aid to the outside diameter if necessary. A version with outside diameter coated with bore sealant is available on request
Can be combined with our axial seals AS-10 and V-rings
Efficient protection against air side contaminations

Applications e.g.:

Mechanical and apparatus engineering
Agricultural machinery
Construction machines
Drive systems, industrial gearboxes, electric motors
