The 150 mm steel shaft sleeve bearing series includes models like 6030, 6230, and 6330, featuring deep groove ball bearings designed for robust performance. The 6230 bearing has an inner diameter of 150 mm, outer diameter of 270 mm, and width of 45 mm, with a basic dynamic load rating of 176 kN and static load rating of 168 kN, suitable for speeds up to 2600 rpm with oil lubrication. The 6330 variant offers a larger outer diameter of 320 mm and width of 65 mm, with dynamic and static load ratings of 276 kN and 274 kN respectively. These bearings typically use chrome steel (SAE52100) and come with various sealing options like open, ZZ, or 2RS for protection against contaminants. They are ideal for high-speed, heavy-load applications requiring durability and precision.
