Radial roller support with two ribs on the outer ring and a smooth inner ring allows free axial displacement between rings, making this a non-locating bearing. Bore diameter is 50.0 mm, outside diameter 90.0 mm, width 20.0 mm, net mass 0.534 kg. Limiting speed reaches 14500.0 1/min, with a reference speed of 6600.0 1/min. The E design provides increased load carrying capacity, and running accuracy is held to P6. The M1 cage is machined from brass, guiding the rollers with stable pocket clearance at the stated speed range. Radial internal clearance C3 compensates for thermal expansion and interference fit growth during operation, which supports steady running at elevated speeds. Since the bearing is a non-locating type, it accommodates axial shaft movement while the smooth inner ring allows free sliding of the outer ring relative to the rollers.
