Design description Radial needle roller and cage assemblies consist of plastic cage bands for needle rollers, which are injection molded by the meter and fitted with rolling elements.7 types are available with needle sizes from Ø 1.5 mm to Ø 12 mm, which are either spooled by the meter or cut to length ready for installation, offered and supplied. The needle rollers (NRB) or cyl. rollers according to DIN 5402 / ISO 3096 are held and guided in the rolling element pockets. Once the insert length has been determined, cutting to length to the required insert diameter can be carried out conveniently and quickly using commercially available cutting tools such as pliers, scissors or similar. When determining the insert length, the cage end clearance recommended by the manufacturer must also be observed. The joint created during assembly remains open. The function of the radial needle roller and cage assembly is not impaired by the open joint. Radial needle roller and cage assemblies are independent of diameter, i.e. they have no maximum limit, provided the minimum operating range is observed (see dimension table). Further variants are noted in the catalog.
