HK Needle Bearings
Drawn
cup needle roller bearings, are needle roller bearings with a deep thin-walled
outer ring with open or closed ends. They have a very low sectional height and
high load carrying capacity. They are used when the housing bore cannot be used
as a raceway and a very compact bearing arrangement is required. Drawn cup
needle roller bearings are generally used directly on the shaft. Where the
shaft cannot be hardened and ground, they can be combined with an inner ring.
Drawn cup needle roller bearings with closed ends
The drawn cup of hardened sheet steel and the needle roller
and cage assembly forms a non-separable unit. The outside surface of the
rollers is slightly relieved towards the roller ends giving a favorable load
distribution in the bearing. The space available for lubricant is large.
Usually they have a single row of rollers. Some may have two-needle roller and
cage assemblies adjacent to each other with the lubrication hole in the outer
ring.
With and without inner rings
For applications where a seal is not available, or cannot be
used, bearings with integral seals may be used. These are rubbing seals of
polyurethane or nitride rubber (NBR). High quality lithium base grease is used
in them. To utilize maximum load carrying capacity, the raceways on the shaft
must have the hardness and surface finish normally found on bearing raceways.
Recommendations will be found in the section.
Needle Roller Bearings Specifications & Standards
- Dimensions: The boundary dimensions
of the drawn cup needle roller bearings are in accordance with ISO.
- Bore Size: Bore is a hollow, usually
cylindrical chamber or barrel where the metal balls are to be placed. Its size is measured
in millimeters.
- Outer Ring Width: It is the width of the outer ring measured in millimeters.
