KOYO 22330RHA is featured RHA type spherical roller bearing for shaker screens. This type of bearing consist of convex asymmetric rollers and a prong type, copper alloy, outer ring guided, machined cage. This cage possesses optimum characteristics for use with shaker screens. And these bearings feature a large load rating capacity and self-aligning capability.

KOYO bearings technical data are introduced in the following for reference,

  

KOYO NJ2213R is featured R type cylindrical roller bearings, single row, the type of bearing feature enhanced load rating compared with standard series due to type R bearing have different internal design. Thus the bearings are mainly used in briquetting machines, rubber mixing equipment and rolling mills.

KOYO bearings NJ2213R technical data are indicated in the following dimensions table, 

  

In rolling bearing 2220, is a more popular open type self-aligning ball bearing for heavy load and impact load machine use, just like precision instruments, low noise machine, automobile, motorcycle, metallurgy, rolling mill, mining, petroleum and sugar industry, etc.
