INA needle roller and cage assemblies

INA needle roller and cage assemblies are single or double row units comprising cages and needle rollers. The single row design is based on DIN 5 405-1.

Since its radial section height is equivalent to the diameter of the needle rollers, needle roller and cage assemblies allow bearing arrangements requiring only a very small radial design envelope. They have high load carrying capacity, are suitable for high speeds and are particularly easy to fit.

If the raceways are produced to high geometrical accuracy, INA bearing arrangements with high runout accuracy can be achieved.

The radial internal clearance can be influenced by the needle roller sort as well as by the shaft and housing tolerances.

INA needle roller and cage assemblies require a hardened and ground raceway on the shaft and in the housing.

INA double row needle roller and cage assemblies are only available in particular enveloping circle diameters FW. These are indicated by the suffix ZW.

Semiconductors

INA needle roller and cage assemblies with a plastic cage can be used at operating temperatures from –20 °C to +120 °C.

INA needle roller and cage assemblies are available with plastic cages and sheet steel cages. Plastic cages have the suffix TV and are only available in particular sizes.

INA needle roller and cage assemblies' suffixes

  • TV: Cage made from glass fibre reinforced polyamide 66 - Bearings with plastic cage
  • ZW: Double row design (certain sizes only)
