K Series Thin Section Bearings

Inch size thin section angular contact ball bearing is the type that widely used in industrial field where the constant section bearing to be used.
This kind of bearing can carry radial load and one-direction thrust load, and is usually used with another bearing with the same structure.
Normally, this bearing should be mounted opposed to another bearing to establish and maintain the contact angle.

Inch size thin section four point contact ball bearing (Type X) is a single row ball bearing, it carries loads from radial and axial both directions, it can replace two bearings and can provide different internal preloads and clearances according to customer needs.

NKAA10CP0-NKG250CP0 Series Thin Section C-Type Open Radial Contact Ball Bearings | Lightweight · Compact Design · Radial Load Optimization​​ Engineered for rotating equipment requiring stringent weight control, the NKAA10CP0-NKG250CP0 Series Thin Section Bearings (Thin Section Ball Bearings) adopt a C-Type Open Radial Contact Ball Bearing structure. Integrating three core design principles—simplicity, lightweight construction, and compactness—this series serves as an ideal solution for radial load applications. As a single-row radial ball bearing optimized with traditional manufacturing processes, its primary load direction is engineered to prioritize radial loads. The inner and outer rings feature a controlled axial displacement design, strategically limiting the number of load-bearing balls to 50% of the full complement. This configuration balances structural simplicity with performance efficiency. While excelling in radial load handling, the C-Type Open Bearings also accommodate unidirectional thrust loads in specific directions, ensuring flexibility to adapt to complex operational demands. Note: For applications with stringent axial load capacity requirements, angular contact ball bearings are recommended—their native design supports combined radial and axial loads. The series offers width options ranging from 3/16″ (4.762mm) to 1″ (25.4mm), making it suitable for diverse mounting spaces.
