Metric Thin Section Radial Contact Ball Bearings | C-Type 8mm, 8mm Sealed, 13mm, 20mm Series

Metric Thin Section Radial Contact Ball Bearings, also known as C-Type thin section ball bearings, are designed with a radial contact raceway structure. This bearing type is mainly used to support radial loads while maintaining a compact cross section, low weight, smooth running performance, and low friction torque.

Compared with A-Type angular contact thin section bearings and X-Type four-point contact thin section bearings, C-Type radial contact bearings are more suitable for applications where the main working load is radial load and the axial load is relatively light. Their compact structure makes them ideal for precision equipment where space saving, lightweight design, and stable rotation are important.

Luoyang Deeplink Technology Co.,Ltd. manufactures LYDL PC series metric thin section radial contact ball bearings for precision instruments, medical devices, optical systems, semiconductor equipment, automation machinery, robot end-effectors, lightweight rotary mechanisms, measuring equipment, and compact mechanical assemblies.

Difference Between 8mm, 8mm Sealed, 13mm and 20mm Series

Metric Thin Section Radial Contact Ball Bearings Structural Features – 8mm Open Series

Metric Thin Section Radial Contact Ball Bearings Structural Features

The 8mm open C-Type series is designed for ultra-compact applications requiring low weight, thin cross section, smooth rotation, and reliable radial load support. This series is suitable for equipment with limited radial space where the main working load is radial load. It is commonly used in optical instruments, compact automation equipment, lightweight rotary mechanisms, medical devices, measuring equipment, and robot end-effectors.

Metric Thin Section Radial Contact Ball Bearings Structural Features – 8mm Sealed Series

Metric Thin Section Radial Contact Ball Bearings Structural Features

The 8mm sealed C-Type series is based on the compact radial contact structure and includes sealing protection for applications where dust, particles, or light contamination may affect bearing performance. Compared with the open type, the sealed type provides better protection and improved grease retention. It is suitable for medical devices, automation equipment, measuring instruments, optical systems, and compact rotary assemblies requiring cleaner operation.

Metric Thin Section Radial Contact Ball Bearings Structural Features – 13mm Series

Metric Thin Section Radial Contact Ball Bearings Structural Features

The 13mm C-Type series provides a balanced solution between compact design, radial load capacity, and rigidity. Compared with the 8mm series, the 13mm series offers higher load ratings and stronger stiffness while still maintaining the space-saving advantages of thin section bearings. It is recommended for precision automation equipment, semiconductor machinery, medical equipment, measuring instruments, rotary mechanisms, and compact mechanical systems requiring stable radial load support.

Metric Thin Section Radial Contact Ball Bearings Structural Features – 20mm Series

Metric Thin Section Radial Contact Ball Bearings Structural Features

The 20mm C-Type series is designed for applications requiring higher radial load capacity, stronger rigidity, and more stable support within a compact bearing structure. Compared with the 8mm and 13mm series, the 20mm series provides a stronger cross section and better stiffness. It is recommended for precision machinery, industrial automation, rotary platforms, aerospace mechanisms, semiconductor equipment, and compact assemblies where higher radial load performance is required.
