KH Series "Heavy Duty" Pre-engineered high precision bearing assemblies

Kaydon's heavy duty turntable bearings are designed to provide precise positioning and stopping, with consistent repeatability, in applications where rotation is constant, intermittent or oscillating. They are the ideal bearing for advanced rotary index tables or any design where the bearing will interface with other precision mechanical components.

The KH Series bearing's unique 4-point contact ball geometry enables one bearing to handle simultaneous radial, axial and moment loading. An internal diametral preload provides greater stiffness and minimum free play. And unlike conventional air bearings, Kaydon KH Series of heavy duty turntable bearings will not lock up in the presence of off-center loads.

Available in 3 popular pitch diameters, in geared and non-geared versions, Series KH "heavy duty turntable" bearings feature a low profile to permit larger work areas above the index table.

Tight deflection and tilt tolerances give KH Series bearings their precision

KH Series bearings are often used in applications where the position of a rotating part relative to the stationary structure is critical. The axis of rotation can be displaced from its true position in three ways-radially, axially, and angularly. These deviations are referred to as radial deflection, axial deflection, or tilt (angular rotation).

Materials of construction and technical data:

Rolling elements - Chrome steel hardened to Rockwell C 60 minimum.

Ball paths (raceways) - Selectively hardened for maximum obtainable bearing capacity. Fourpoint internal design permits acceptance of combination axial, radial, and moment loads.

Geared and ungeared rings - Rolled high carbon steel forgings quenched and tempered to 262 BHN minimum

Gears - Involute Stub, 20° pressure angle, AGMA quality 8

Seals - Nitrile rubber seals provide positive contact for retention of lubrication and exclusion of contaminants Lubrication–Multi-purpose lithiumbased, NLGI No. 1 E.P. grease

The three tables from our online catalog show stiffness of standard heavy duty slewing bearings. If your application requires increased stiffness, Kaydon can often supply a stiffer bearing in the same envelope dimensions. Call us at (800) 514-3066 or submit your inquiry.

We invite you to consult with Kaydon prior to selecting a pre-engineered, in stock, large-diameter bearing.
