NEEDLE BEARINGS AND BEARING WITH LONGES CYLINDRICAL ROLLER
Needle bearings and bearing with longes cylindrical roller consist of one or two rings
and a set of needle (longes cylindrical) rollers with a cage. The most considerable advantage of
needle bearings and bearing longes cylindrical roller is high load rating when the height of crosssection is low.
Needle bearings and bearing with longes cylindrical roller without rings found s wide application owing to low cross
section that is specially applicable for smallsize and light designs.
Comperatively long to the diameter, needle rollers and longes cylindrical roller provide supports creation
of high load rating and rigidty. As needle (longes cylindrical) rollers have spherical ends,
they can remove edge stresses.
