This
heavy duty plain bearing was required to replace some existing bearings on a
bridge, so had to be designed with critical dimensions as the original.
Two sizes were required, 4" and 5", They were designed with
steel housings due to the high loading required.
The safe load rating on the 4" bearing was 35 Tons, and on the
5" 50 Tons.____________________________________________________________________________________________________________________

A customer in Europe was having difficulty finding bearing
housings for a 500mm shaft in a crusher. 239/530K bearings were to be used
and the housing needed to be in steel and delivered in 4 weeks.
Criptic Arvis designed and delivered the housings in the
required 4 weeks.
We can do the same for your company.

A
customer contacted us because he had some housings and bearings that
needed replacing. The units were working on a funicular railway which had to
shut down due to not being able to get the obsolete units.
Criptic Arvis came to the rescue, producing cast iron housings and replacing the bearings. After assembly of the bearing, end covers incorporating seals were fitted.
If you have obsolete units, we can help.

A batch of
these parts were required in Stainless steel. ARVIS came to the rescue.

A
customer approached Criptic Arvis to see if we could help him to solve a
problem. He had bearings running in chemicals interspersed with wood chips, and
the bearings were only lasting about a week due to the ingress of foreign
bodies. The units needed to replace the original blocks without needing to
redesign other components.
The solution was solved by designing a block with five seals so that chemicals and other materials could not penetrate to the bearing.
To get to the bearing, the contaminant would have to pass a Vee face seal, a felt seal. a filled grease cavity, a second Vee seal and then a lip seal.
The units have been running successfully since 2002.
