Needle Roller Bearing Types
Needle Roller Bearing
A Needle Roller Bearing is a type of roller bearing that uses long, thin cylindrical rollers (called needle rollers) as rolling elements. Because the rollers are very small in diameter compared to their length, the bearing has a very compact cross-section yet offers a high radial load capacity.
Single Row Needle Bearing
A Single Row Needle Roller Bearing has one row of needle rollers between the inner and outer raceways. It is designed to carry radial loads in a very compact space.
Double Row Needle Roller Bearing
A Double Row Needle Roller Bearing consists of two rows of needle rollers arranged inside a common outer ring. It is designed to carry very high radial loads while still keeping the cross-section compact compared to other roller bearings (like cylindrical roller bearings).
Needle Thrust Roller Bearing
A Needle Thrust Roller Bearing (also called Thrust Needle Bearing) is a type of thrust bearing that uses needle-shaped cylindrical rollers as rolling elements. It is designed to carry very high axial (thrust) loads in one direction while occupying minimal axial space.
Drawn Cup Needle Roller Bearing
A Drawn Cup Needle Roller Bearing (DCNBR) is a needle roller bearing with a thin-walled, deep-drawn outer cup (outer ring). Because the outer ring is pressed from sheet steel, it is very thin, which gives the bearing an extremely compact radial cross-section and makes it lightweight..
Combined Radial Axial Bearing
A Combined Radial-Axial Bearing (also called Combination Bearing) is a special type of bearing designed to handle both radial and axial (thrust) loads simultaneously in one unit.A Combined Radial-Axial Bearing = Needle roller bearing (radial) + thrust bearing (axial) in one compact unit → ideal where space is limited but both load types exist.
