KH Series Pre-engineered high precision heavy duty turntable bearing assemblies KH Series 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 heavy duty turntable 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 precision 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 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, and tilt (angular rotation). The three tables from our printable heavy duty turntable bearings pdf catalog show stiffness of standard KH Series 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. Materials of construction and technical data
