This deep groove ball bearing carries radial and moderate axial loads in a single row of balls, with a bore diameter of 150.0 mm, outside diameter of 225.0 mm and width of 35.0 mm. It is built with a steel sheet metal cage (JN) and seals on both sides (2RSR), giving a net mass of 4.3 kg and a limiting speed of 1540.0 1/min. Radial internal clearance is CN (Group N), standard bore type Z. The integrated seals keep grease inside and contaminants out, so the bearing runs without external sealing arrangements and needs no relubrication schedule beyond its initial fill. Standard CN clearance suits normal running fits and moderate operating temperatures, while the steel cage guides the ball set reliably at the stated limiting speed. Dimensionally and constructionally equivalent to SKF 6030-2RS1, NSK 6030DDU and NTN 6030LLU.
