spacer Kaydon Bearings - Ball bearings

At Kaydon, we apply Thinfinite® engineering experience and expertise to solve the world's most unique bearing challenges. The Kaydon Reali-Slim® inch-standard bearing is one of the most widely used thin section bearings in the world. Kaydon Thinfinite® bearing solutions save weight, create space, reduce friction, increase design flexibility, and provide excellent running accuracy.

Kaydon bearings are available in the industry's largest variety of materials, separator options, cross sections, internal fit up choices, lubricants, corrosion resistance options, contact angles, and precision levels. Our Reali-Slim® bearings meet the most demanding specifications in a broad range of applications including:

  • Aerospace and defense
  • Astronomy instrumentation
  • Fixturing and workholding equipment
  • Food processing equipment
  • Glassworking equipment
  • Index and rotary tables
  • Packaging equipment
  • Machine tools
  • Medical systems and medical devices
  • Optical scanning equipment
  • Tire making equipment
  • Radar, satellite and communications equipment
  • Robotics
  • Textile machinery
  • Tube and pipe cutting machines
  • Semiconductor manufacturing equipment
  • Sorting equipment

Kaydon bearing selector

 
The Kaydon bearing selector allows you to search our standard thin section bearings by dimension or part number. Results include downloadable 2D and 3D drawings.

open bearings

 

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.
 

spacer
sealed bearings

 

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.

Endurakote corrosion-resistant coating for Reali-Slim bearings

 

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.
 

spacer
Stainless steel Reali-Slim bearings

 

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.
 

spacer
metric bearings

 

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.
 

spacer
Ultra-Slim bearings

 

Ultra-Slim® extra thin section bearings
Kaydon Ultra-Slim® extra thin bearings offer Thinfinite® 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.
 

spacer
Reali-Slim TT turntable bearings

 

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.

BB series metric ball bearings
When factors such as cost, availability, corrosion resistance, tighter tolerances, torque, seal/shield options, and temperature resistance are important in your application, it pays to consider BB series four-point contact metric bearings as an alternative to cross-roller bearings. The additional design flexibility they offer can often help you achieve your design objectives with optimum performance and economy. BB series metric bearings are available to match the bores and widths of common cross-roller bearings and, unlike standard crossed roller bearings, BB series ball bearings include a protective package.

Bearings for demanding applications
Kaydon Reali-Slim® thin section hybrid bearings are specifically engineered for service in the most severe or extreme environments. Tremendous benefits in performance can be obtained by matching not just size but also material to the application. These alternative race and ball materials interact differently from traditional chrome steel bearings. Kaydon stainless steel bearings are used where high precision and corrosion resistance are required.

KT tapered roller bearings
Kaydon's unique concept of standard bearings with light weight, thin sections, and large bore diameters includes tapered roller bearings as well as ball bearings. Kaydon KT series tapered bearings offer advantages to designs that would benefit from the many unique advantages of a thin section bearing but require a bearing of higher capacity and/or less space or weight. KT tapered roller bearings are ideal for applications ranging from oil field equipment to machine tool tables.
