Product Description

NADELLA Needle Roller Bearing RNA2095

1. Instruction of Needle Roller Bearings:
Needle roller bearings are roller bearings with cylindrical rollers that are small in diameter. In spite of their low cross section, needle roller bearings have a high load carrying capacity and are therefore extremely suitable for bearing arrangements where radial space is limited.

2. Needle roller bearings design include:

- Drawn Cup Needle Roller Bearings
- Solid Cup Needle Roller Bearings
- Cage and Needle Roller Assemblies
- Inner rings for Needle Roller Bearings
- Cam and Roller Followers
- Needle Rollers
- Needle Roller Thrust Bearings
- Combined Needle Roller Bearings
Model HK, TA, TLA, open-end drawn cup needle roller bearings with retainer,
Model BK close-end drawn cup needle roller bearing with retainer,
Model SCE, BA, J, JH, drawn cup needle roller bearings (Inch series).

3. Application:
Automotive transmissions, air-conditioner compressors, bulldozer blades,
overhead traveling cranes, gearboxes, machine tool spindles, copying machines and many more.

NA, RNA type
CLUNT standard needle roller bearings NA type, outer side with ribs or elastic locking collar, no inner wall. And a single and double row roller two structural types. And whether single or double row needle roller bearings, inner ring can be made of the NA-type or without inner structure type RNA type.
An annular lubrication grooves and lubrication holes large series of needle roller bearing outer ring. NA-type needle bearing outer ring assembly (outer ring, needle roller and cage) can not be separated, but if the inner ring can be separated from the outer components.
Needle roller bearings without inner ring in direct contact with the journal surface, can further reduce bearing radial mounting position size requirements. But requires the journal surface hardness and dimensional accuracy should meet the technical requirements of the respective bearing raceways.

NAV, RNAV type
NAV type and RNAV type is not with cage full complement needle roller bearings. Type in the NA and RNA derived based on the bearing structure. Its carrying capacity greater than the NA type and RNA type bearings, but the speed is lower than the performance of NA type and RNA type bearings. At high speed is not suitable for working conditions to use.

NAO type
NAO inner and outer rings no wall, there are single or double row needle. When the double row needle, outer ring with lubrication grooves and lubrication holes.

K type
   K type known as "needle roller and cage assembly," no bearing inner and outer rings of the structure. It is the smallest radial bearing a class of bearings. Which the shaft surface and bearing surface to work as a raceway, therefore, requested with matching hardness and dimensional accuracy of the shaft surface and the bearing surface shall be substantially meet the corresponding technical requirements bearing raceways.

Long cylindrical roller bearings
Long cylindrical roller bearings, bearing similar characteristics with the use of needle roller bearings, but radial cross-section than the large size bearings needle roller bearings, and therefore can withstand greater radial load.
Long cylindrical roller bearings and needle roller bearings needle, its ratio of length to diameter (aspect ratio) greater than 3, the difference lies in long cylindrical roller bearing roller diameter greater than 5 mm. Therefore, in a structural form, long cylindrical roller bearings and needle roller bearings have many of the same structure.
Long cylindrical roller bearings with needle bearings, can only bear the pure radial load, can not limit the axial displacement of the bearing, bearing installation, it does not allow the axis of the inner and outer ring axis angular error generated.

NAOL type
NAOL type and needle roller bearing NAO same structure. Inner and outer rings are no ribs,

NAL type
NAL same type and NA-type needle bearing structures. Outer side with ribs or elastic locking collar, no inner wall.
