SKF 6306-2RS1NR C3HT51 Deep Groove Ball Bearing

SKF 6306-2RS1NR/C3 is a single-row deep groove ball bearing with a 30 mm bore, 72 mm outer diameter, and 19 mm width, designed for compact radial support in a variety of machinery. It has two elastomer seals (2RS1) on opposite faces to shield against dust and moisture and to minimize friction, while the NR suffix indicates a snap ring groove in the outer race for axial retention in compatible housings. The C3 clearance designation means greater-than-normal internal clearance, allowing for thermal expansion and certain operating conditions without compromising performance. This combination of sealing, outer-ring groove for retention, and clearance class makes it a versatile choice for applications that demand reliable low-friction radial support in compact packages.
