Axial and radial bearing elements
The axial-radial roller bearings are heavy-duty, very rigid and accurate bearings used for the bearing support of ball screws in machine tools. They are directional in all axes of rotation: axial, radial and diagonal.

Axial and Radial bearinglements
Radial needle roller and cage assemblies consist of plastic cage bands for needle rollers, which are injection moulded by the metre 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 metre 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, it can be cut to the required insert diameter quickly and easily 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 affected by the open joint. Radial needle roller and cage assemblies are independent of the diameter, i.e. they do not have a maximum limit, taking into account the minimum application range (see dimension table).
Further variants are noted in the catalogue.

Technical description
KMF angular contact ball bearings of type series SKE are low-friction, ready-to-fit installation elements with high accuracy for high speeds, high axial and radial load carrying capacity and high tilting rigidity. SKE insert elements have raceways arranged at an angle of 45° to the bearing axis. The bearing rings are slotted. The KMF angular contact ball bearing insert element SKE consists of 2 hardened ball races with ground or machined raceways and ball cage (closed) with guided and retained balls. Ball races are made of hardened rolling bearing steel hardness 60-63 HRC , ball cage (composite construction) polyamide PA 12 with carrier body made of steel, balls DIN 5401 hardened rolling bearing steel 100 Cr6 hardness 59 ÷ 65 HRC / grade 10. Limiting temperatures of the bearing are -40°C and +100°C in continuous operation, +120°C in short time operation.
