This bearing housing accepts a bearing with a bore diameter of 30.0 mm and is secured to the shaft by grub screws set into the inner ring, so no separate locking collar is required. The four-bolt flanged cast iron body of the RMEY30-XL-N features a centring spigot for precise alignment with the mating flange face, has an overall width of 38.1 mm and a net mass of 0.96 kg. The basic dynamic load rating is 20700 N. R seals fitted on both sides of the unit retain the grease charge and keep out dirt and moisture, allowing operation without additional external sealing. The grub-screw fixation and centring spigot suit applications where the housing must be located accurately on a flange and where periodic relubrication through the housing is expected.
