SKF - Rolling Bearings

14 Track runner bearings
Designs and variants
Track runner bearings are designed to run
on all types of tracks and to be used in cam
drives, conveyor systems, etc. These bearings
have a thick-walled outer ring, which enables
them to accommodate high radial loads, while
reducing distortion and bending stresses.
The outer ring running surface is crowned
as standard. This is beneficial for applications
where angular misalignment relative to the
track may occur or where edge stresses need
to be minimized. With the exception of single
row cam rollers, track runner bearings are
also available with a cylindrical (flat) outer ring
running surface.
SKF supplies track runner bearings greased,
sealed and ready to mount.
SKF supplies track runner bearings in many
different types and designs, and for a wide
variety of operating conditions and applications.
The assortment comprises:
Cam rollers
Single row cam rollers
SKF single row cam rollers († fig. 1) are based
on deep groove ball bearings in the 62 series.
They are supplied greased and capped with a
sheet steel reinforced NBR contact seal on
both sides.
Double row cam rollers
SKF double row cam rollers († fig. 2) are
based on double row angular contact ball
bearings in the 32 dimension series and have a
30° contact angle. They are supplied greased
and capped with a sheet steel shield on both
sides, which extends into a recess on the inner
ring.
