SKF 6303-2Z Ball Bearing

SKF Explorer bearing 6303 2Z - non-disassemblable single-row radial ball bearing with a steel cage guiding the balls, featuring non-contact metal shields on both sides and normal radial clearance. The shields of the 6303-2Z bearing are pressed into grooves on the outer ring and fit against the smooth inner ring. The 6303 2Z bearing is designed for mounting with a rotating inner ring and is filled with high-quality lubricant with a temperature range from -40°C to +100°C for the entire lifespan of the bearing. If the outer ring rotates, lubricant leakage may occur at higher speeds. SKF 6303-2Z Explorer class bearings represent a new group of high-performance rolling bearings, offering significant improvements in key operating parameters such as noise, vibration, heat generation, operational reliability, dynamic load capacity, and are manufactured with higher precision than standard bearings. The dimensional accuracy corresponds to the precision class P6.
