HS Series

High-Capacity Slewing Ring Bearings

HS Slewing Ring Bearings
HS Series slewing ring bearings provide exceptional load
and thrust capacity in a surprisingly small envelope.
They are similar in size to Kaydon’s popular RK series, but
have a rectangular cross-section and less internal
diametral clearance. This lets them handle about twice
the moment load (up to 139,900 ft-lbs.).
HS Series bearings feature a 4-point contact design,
deep groove gothic arch raceways and a maximum ball
complement. They are available in sizes from 20” to 47”
O.D. (500mm-1,200mm), with internal gearing, external
gearing, or no gearing. All have integral seals to
protect against contamination and two fittings
for lubrication.
For more details and a comparison with
the RK Series, please see the other side of
this sheet.

Stocking Program
Kaydon stocks many HS Series
bearings and all forgings, ready to
be machined. Mating pinions (the
same used in our RK Series) are also
generally available.
