Kaydon equal-section thin section bearings stand out in precision motion systems for their constant cross-section design. Unlike standard ball bearings that grow thicker as bore size increases, Kaydon thin bearings maintain the same cross-sectional dimensions regardless of bore diameter. This unique design saves valuable installation space, reduces component weight, and keeps consistent stiffness, making them a top pick for robotics, medical equipment, radar, optical instruments and aerospace automation.
Kaydon’s core equal-section thin bearing lineup is split into three primary series: Type A, Type C and Type X, each built for different load requirements.
Type A (Angular Contact) is designed to handle combined radial and axial loads. It supports thrust loads from one direction and suits applications with axial offset or moment loads. Engineers often use Type A bearings for rotating platforms, optical turrets and precision rotary joints.
Type C (Radial Contact) is the most widely used general-purpose model. It carries radial loads mainly and delivers smooth, low-friction rotation. If your application only needs radial load support and simple alignment, Type C is the economical and reliable option. It is common in light-duty rotary tables and inspection instruments.
Type X (Four-Point Contact) is also called a gothic arch bearing. It can bear radial, axial and tilting moment loads at the same time. This is the preferred choice when space is extremely limited and complex combined loads exist, such as robot joints and surveillance camera gimbals.
When selecting Kaydon equal-section thin section bearings, start with your load type first. Pick Type C for pure radial loads, Type A for one-way axial plus radial loads, and Type X for compound moment loads. Next, confirm inner bore size, radial clearance and seal style: open types work for clean, well-lubricated environments, while shielded or sealed variants block dust and moisture for harsh workshop conditions. You should also check speed limits and material options; stainless steel versions are available for corrosion-prone environments.
It is critical to note that thin-section bearings are sensitive to improper mounting and overload. Even premium Kaydon models will deform prematurely under excessive force. Always follow the manufacturer’s mounting torque and preload recommendations.
In short, Kaydon Type A, C and X equal-section thin bearings offer flexible solutions for compact precision machinery. Correct model selection based on load profile ensures long service life, high rotation accuracy and stable equipment performance.
