Only from KAYDON®: REALI-SLIM TT® Series —
the new generation of small-scale,
thin-section turntable bearings
To save weight, reduce product design envelope sizes
and increase design flexibility — without compromising
bearing performance and life — customers told us
they’d welcome a more compact turntable bearing
design.
We listened and responded, by designing the first smallscale, thin-section turntable bearings available for such
demanding applications as robotics, radar antennae,
and factory positioning and inspection tables…
REALI-SLIM TT® Series. The advantages of this new
series vs. conventional turntable bearings include:

Custom configurations to meet your application’s
specific needs — many drive options, gearing/timing
belt, mounting hole types; and
Designed to withstand harsh operating environments
— AISI-440C steel races, steel reinforced seals.

Significantly smaller size for greater design versatility
and reduced weight;
Greater accuracy — extended radial bearing section
increases rigidity, and optional preload or clearances to
meet application torque or deflection requirements;

Four-Point Contact Bearing
(REALI-SLIM TT® Series)
Bearings are most often designed to handle either radial
or axial load conditions. The unique feature about the
REALI-SLIM TT® Series four-point contact bearing line is
that the gothic arch geometry of the inner and outer
races enables a single bearing to carry three types of
loading (radial, axial and moment) simultaneously. This
makes it the bearing of choice for many applications since
a single four-point contact bearing can often replace two
bearings, providing a simplified design.

REALI-SLIM TT® Series bearings may also be furnished
with an internal diametral preload for those
applications requiring greater stiffness or zero free
play. This is accomplished by using balls that are larger
than the space provided in the raceways. The balls and
raceways, therefore, have some elastic deformation in
the absence of an external load.
