Cam Runners ™
Osborn Cam Runners are
significantly different
from conventional needle
bearing style cam
followers. This product is
protected by U.S. patent
and other patents pending
this assembly is used as a direct
replacement for a conventional cam
follower, the life will be optimized if
the cam or other mating surface is
within the range of 55 - 60 Rc. Softer
or harder materials may result in
decreased life, particularly under high
loads. The mating surface must be
free of grease, oil and abrasive
contaminants.
Advantages
No lubrication required – ever!
Non sparking and low electrical
conductivity
Thrust load tolerant
General Characteristics
Extended life, ideal for difficult-to-
service-operations
Cam Runners are manufactured with a
composite synthetic tread and stainless
steel stud. The composite tread
consists of two different synthetic
materials chosen to provide optimal
characteristics for the outer wear
surface and the inner bearing surface.
The two synthetic parts are molded
together to form a single mechanically
bonded assembly that is mounted on
the stud, eliminating the need for
convential seals and lubricants. The
outer tread material offers high
mechanical strength while the inner
bearing material provides high
lubricity.
This assembly is dimensionally
interchangeable with conventional
steel cam followers. Because of its
unique construction, comparable load
ratings are not applicable. In order to
guide you in choosing applications,
extensive testing has been utilized to
develop life expectancies based upon
continuous duty testing at various
speeds and loads. In continuous duty
operation under identical loads and
speeds, the Cam Runner has been
found to outlast conventional steel
cam followers by an average of 10
times!
No lubricant leakage to
contaminate your process
Quiet operation resulting from no
internal moving parts
Wide range of operating
temperatures
Manufactured under ISO 9001
certified quality system
Not recommended for ambient
temperatures above 250° F, highly
abrasive applications or repeated
heavy shock loads.
Bearing to stud clearance is greater
than for needle bearing designs and
will increase during early use and will
stabilize after ”wearing in“.
The stud provides optimum life and
corrosion resistance. Tread bearing
wear is critically dependent on the
hardness of the mating surface. When
