REALI-SLIM® Bearings Catalog 300 ©KAYDON® Corporation Issue 10 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. Figure 2-12 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; Steel Reinforced Seals Easier to use — fast installation and changeout; Geared Race The configurations and specifications you need for more compact, more precise turntable designs Example of part number breakdown T T = -point contact radial 4 Inner Hole Gearing ball bearing I E = External Gear A = nner Hole Style of 01 = Ball size in (1/8) inch through holes N = Internal Gear 00225 = Ball pitch diameter P = Plain - no gear B = Tapped mounting holes in inches x 100 C = Countersunk mounting holes Outer Hole A = Outer Hole Style of through holes B = Tapped mounting holes C = Countersunk mounting holes Holes sized for #4-40 screws, tapped, countersunk, or through gears set at full depth involute, 64 DP., 20° pressure angle 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.
