Sometimes called "Self-Lube" bearings (a generic name derived from the NSK-RHP registered trademark for this style of wide inner ring bearing). They consist of a deep groove ball bearing (usually with a spherical outer diameter) mounted in a 2-piece pressed steel or 1-piece cast iron housing. The housings come in a wide range of styles which are easy to fit. 

Be aware that there are sometimes small differences between western (e.g. RHP) and Eastern brands that may be important to your application. This is particularly true for the round, spigoted UCFC or MFC ranges.
