Single Row Cylindrical Roller Bearings

Single-row roller bearings can sustain high radial loads and are suitable for high speeds. These bearings are separable, making their assembly and disassembly easier. Both bearing rings can be fixed when required. The modified shape of their functional surfaces prevents harmful edge stresses at the ends of the rollers.

Cylindrical roller bearings are produced with several different variations on their internal design.

Cylindrical roller bearings are classified into the following types, depending on whether they have ribs on their rings:

• Type NU – Two solid ribs on the outer ring and an inner ring without ribs. This type is suitable as a free-end bearing.
• Type N – The inner ring has two solid ribs and the outer ring has no ribs. This type is suitable as a free-end bearing.
• Type NJ – Two solid ribs on the outer ring and the inner ring has one rib. This bearing can therefore sustain limited axial loads in one direction.
• Type NUP – Two solid ribs on the outer ring and the inner ring has one rib and flat angle ring. (HJ type L-shaped thrust collar.)
  
  

An NJ-type bearing with a HJ-ring can perform the same function as an NUP-type bearing.
