Carries radial loads and moderate axial loads in a single row of balls running in deep grooves, which keep the rolling elements guided without a separate thrust bearing. Bore diameter is 150.0 mm, outside diameter 225.0 mm, width 35.0 mm, net mass 4.12 kg. The cage is a sheet steel design, symbol JN. Limiting speed is rated at 3950.0 1/min, reference speed at 3850.0 1/min. Radial internal clearance is CN (Group N), the standard clearance range, suited for shafts and housings with normal fit tolerances and no unusual thermal or fit-related preload. The design carries no seals or shields, so lubrication and contamination protection must be provided externally. Equivalent references: SKF 6030, NSK 6030, NTN 6030.
