Key Performance Features

01. Effective Double Sealed Protection

Features dual contact rubber seals (2RS) that provide superior protection against dust, moisture, and particulate contamination . This sealing solution effectively retains pre-lubricated grease within the bearing while excluding harmful contaminants, significantly extending service life in demanding environments and reducing maintenance frequency .

02. Inch-Dimension Convenience with Metric Performance

Manufactured to precision inch dimensions (1.5" × 2.625" × 0.5625") while delivering load ratings comparable to metric bearings of similar size. This makes the R24-2RS an ideal choice for legacy equipment, imported machinery, or new designs where inch-system components are specified .

03. Robust Chrome Steel Construction

Constructed from high-grade SAE 52100 chrome steel with precision-ground raceways and balls for smooth, quiet operation . The deep groove geometry accommodates moderate radial loads while supporting light axial loads in either direction, making it suitable for diverse mechanical applications .
