HS6-16E1Z Slewing Ring Bearing Turntable Bearing for Aerial lifts

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.

HS vs. RK: more capacity in the same space

The HS Series offers up to twice the static capacity of our RK Series in the same envelope. Although they use the same pinion, gear, and ring hardness, HS and RK bearings have different designs, clearance and mounting arrangements. 


Kaydon's HS slewing ring bearings provide a variety of solutions for medium to heavy-duty applications including:


|Aerial lifts

|Digger derrick

|Chute swivels

|Lift truck rotators

|Industrial turntables
