This bearing housing carries a 20.0 mm bore and combines a cast iron four-bolt flanged body with an eccentric locking collar for the insert bearing. Basic dynamic load rating is 13600.0 N, and the unit weighs 0.63 kg net. The design uses R seals to protect the bearing interior from contamination. The eccentric locking collar allows secure fixing of the shaft to the inner ring without set screws, keeping the assembly compact and simple to install. The four-bolt flange pattern suits mounting where load is transmitted through a flat surface, and the R seals provide basic protection against dust and debris while permitting standard grease lubrication and re-greasing through the housing.
