C-Type Sealed Radial Contact Thin-Section Bearings (Deep Groove Ball Structure): Engineered for Low Torque, Lightweight Efficiency, and Compact Performance

Type C Sealed Radial Contact Thin-Section Bearings, featuring a precision deep groove ball structure, are specialized solutions designed to deliver exceptional low-torque characteristics, lightweight efficiency, and compact dimensional profiles. Widely deployed in critical applications such as radar systems, armaments, and precision instruments, these bearings balance high-performance functionality with the stringent space constraints of modern engineering.

Standard configurations incorporate double-sealed designs to maximize contamination resistance and extend service life; single-side sealing variants are also available to accommodate unique operational environment requirements. Seals are precision-engineered from nitrile rubber (NBR), ensuring robust defense against dust, moisture, and other contaminants while maintaining reliable performance in harsh industrial or outdoor conditions.
