Thin Section Bearing Information

Thin section bearings have small width cross sections with respect to their diameters. They are designed to save space, decrease weight and reduce friction. Thin and extra thin bearings are available in inch, metric, chrome and stainless steel. Thin section bearings are available as full complement or with cages designed for high speed applications.


Reali-Slim® thin section open bearings

The Kaydon Reali-Slim® bearings series is based on a single cross section which remains constant as the bore diameter is increased (in sharp contrast to standard bearings, in which the cross section increases as the bore diameter increases). By using the same series of Reali-Slim® bearings throughout a product line, the designer can standardize on common components.

Endurakote®-plated Endura-Slim® bearings

Kaydon’s proprietary Endurakote® hard chromium plating protects bearings from corrosion and provides substantial life improvements in hostile environments, achieving the corrosion resistance normally found only in stainless steel bearings, but at a lower cost. This is particularly beneficial for large diameter bearings or where quick delivery is critical.

Reali-Slim MM® thin section metric bearings

Kaydon Reali-Slim MM® series products provide compact, lightweight designs for applications requiring metric envelope dimensions or dimensional interchangeability with other products.

Reali-Slim TT® thin section turntable bearings

Kaydon Reali-Slim TT® series are the first small-scale, thin section turntable bearings available for such demanding applications as robotics, radar antennae, and factory positioning and inspection tables. Kaydon turntable bearings save weight, reduce product design envelope sizes and increase design flexibility.

Reali-Slim® thin section sealed bearings

Kaydon Reali-Slim® sealed bearings offer integral sealed and integral shielded bearings, providing a very compact overall design with the additional advantage of protecting the bearing before, during and after installation.


Reali-Slim® stainless steel thin section bearings

Kaydon stainless steel bearings are used where high precision and corrosion resistance are required. AISI 440C stainless steel Reali-Slim® thin section bearings minimize the surface degradation and particulate formation so common to harsh environment applications.


Ultra-Slim® extra thin section bearings

Kaydon Ultra-Slim® extra thin bearings offer many possibilities where precise positioning and lightweight designs are critical. Precision-engineered Ultra-Slim® bearings are made of stainless steel for corrosion resistance. These low profile, precision ball bearings are ideal for robotics, inspection equipment, satellites, cameras and similar light and medium duty applications with slow or intermittent rotation.
