Hardened Steel Jaw Bushing
In the Jaw Bush principle, tooth and space width are staggered by a
certain measure. In the relaxed state, the bush is ovesize to its
housing bore. However, upon insertion into the housing bore, the
compression of the bush within the elastic limit of the hardened
material allows the teeth to touch on one side. The perspective view
shows that the tooth flank pressure results in a tangential force. In
combination with the radial acting spring force, a higher contact
pressure results between bush and
casing. The higher the ratio between
bush wall thickness and diameter, the more active is the surface
The toothed slot allowing for a nearly closed surface in the slot
region, gives a good all round bearing. Slot position is as a rule
This principle results in an increased seating capacity of the Jaw Bush

and pressing out are easy. Harmful tensions, seating and assembly
problems, associated with plain bushes, can be avoided.
Higher wear resistance chrome-vanadium spring steel is used for the
standard Jaw Bushes.
For special applications in corrosive medium, hardened INOX steels are
increased quality and precision, Precision Jaw Bushes with ground and
fine turned surfaces will meet the requirements. They all correspond
with the works standards.
Grease grooves and channels can be incorporated on both Bore and OD.
