Detailed Product Description

1. ZINA-radial needle roller and cage assemblies is an independent roll element. The space between the two guiding faces of the cage is wide, it not only can guide the needle correctly, but also can keep the needle in the shaft and housing both can be used as the raceway. When the raceway of the shaft and the housing are machined to its regulated dimension accuracy and geometry precision, the bearing can obtain its high precision rotation in the limited space.

2. Structure of radial needle roller and cage assemblies can be regulated to single row and double row. In order to meet special requirement, the cage can also be split.

K radial needle roller and cage assemblies

K---D split radial needle and cage assemblies

K---ZW double row radial needle and cage assemblies

K---DZW split double row radial needle and cage assemblies



3. The main structures of the cage of this kind bearing include M type and K type. The material of the cage is normally high-class carbon structural steel, high-class low carbon alloy steel such as 15CrMo, 20CrMo etc. or plastic cage also can be used according to the requirement. After treated chemically, the steel cage has enough strength and abrasion resistance. The plastic cage can be used in the temperature of 120, and in 180 temporarily.
