| Radial NeedleRoller And Cage Assemblies K series or K...ZW series |
| 1).Overview: Needleroller and cage assemblies are a complement of needle rollers held in placebya cage. The mating shaft and housing are normally used as inner and outerraceways. The unitized design allows for easy handling and installation.Controlled-contour rollers reduce end stresses and permit operation undermoderate misalignment. A variety of cage designs, styles and materials, aswell as multiple roller paths and segmented constructions, meet broadapplication requirements. |
| 2).Sizes: 6 mm -150 mm bore. |
| 3)Markets:Automotive and truck transmissions, agricultural and constructionequipment,two-cycle engines, pumps and compressors. |
| 4)Features: Specialcoatings and platings; split and segmented designs for simplifiedmounting;engineered polymer cages. |
| 5)Benefits: Highload capacity and high limiting speed within the smallest envelope |
