Thin section bearings
Thin section bearings are designed to save weight, use less space, reduce friction, increase design flexibility and provide high running accuracy.
These bearings can meet highly demanding and specific requirements. They are often used in applications such as aerospace, medical systems, robotics, astronomy instrumentation and machine tools. Our design efficiency can lead to significant savings in space, weight and cost over standard dimensioned bearings.
Explore our large variety of thin section bearings, materials, cage/separator options, cross sections, internal clearance or preload choices, lubricants, corrosion resistance options, contact angles and tolerance classes. Our thin section bearings can also be customized to meet your specific performance requirements.

Customized thin section bearings
Customized thin section bearings are designed to provide a comprehensive assortment of bearings for a wide range of applications. They are available in three different main bearing categories:
- Reali-Slim TT turntable bearings
- BB series metric ball bearings
- KT series tapered roller bearings
KT series thin section tapered roller bearings
KT series thin section tapered roller bearings are designed primarily for radial load applications. Since these bearings have a contact angle of approximately 12° under axial load, they can accommodate a reasonable amount of axial load.
Tapered roller bearings feature a cup and cone assembly. The cup is comprised of the outer ring and the cone assembly consists of an inner ring, rollers and a cage. The projection lines of the raceways meet at a common point on the bearing axis defined by the contact angle α (apex point A, fig. 1) to provide a true rolling action and therefore low frictional moments during operation.
KT series tapered roller bearings can be customized to meet specific application needs.

BB series metric thin section ball bearings
BB series metric thin section ball bearings are based on a four-point contact ball bearing. They are designed to match the bores and widths of common cross-roller bearings. With additional features not commonly available in standard cross-roller bearings, BB series bearings provide beneficial design flexibility. The bearings can be further customized to meet specific application needs.
Reali-Slim TT turntable thin section bearings
Reali-Slim TT turntable thin section bearings have inner and outer ring raceway designs that enable them to accommodate radial, axial and moment loads simultaneously. They are based on a sealed four-point contact ball bearing and are available in three different designs:
- bearings without a gear (fig. 1)
- bearings with an external (outer ring) gear (fig. 2)
- bearings with an internal (inner ring) gear (fig. 3)
Kaydon standard Reali-Slim TT turntable thin section bearings are made of stainless steel. The bearings can be customized to meet specific application needs.
