Angular contact needle ball bearings

Needle angular contact ball bearings NKIA and NKIB are designed with an inner ring. The NKIA series corresponds to DIN 5 429-2. It can be loaded axially on one side. Needle angular contact ball bearings are a combination of a radial needle roller bearing and a radial angular contact ball bearing. The radial loads are absorbed exclusively by the needle bearing and the axial loads exclusively by the angular contact ball bearing. These particularly low-profile rolling bearings permit high speeds and can absorb high radial and small axial loads. We have these bearings open on both sides in two series. These are the camps of: NKIA and NKIB. The bearings are not self-retaining. The inner ring can therefore be installed separately from the outer ring with needle roller and ball set. However, it must be ensured that the bearing rings are not mixed up with rings from other bearings. Needle and angular contact ball bearings must therefore remain together as delivered. Depending on the application, the needle angular contact ball bearings can be lubricated with both grease and oil. In the case of grease lubrication, the radial and axial bearing parts should be filled with the same lubricating grease before installation. Needle angular contact ball bearings with alternating axial forces. Needle ball bearings have a narrow and a wide inner ring. The ball cage of the axial part is made of plastic. At the connection point of the inner rings, there is a shoulder on both sides to guide the ball race. As a result, these bearings are also suitable for absorbing alternating axial forces. The needle angular contact ball bearings guide the shaft with an axial play of 0.08 mm to 0.25 mm. NKIA and NKIB can be lubricated with grease or oil. The outer ring has a lubricating groove and a lubricating hole for lubrication. Operating temperatures from -20 °C to +120 °C are possible. The radial cages are made of sheet steel or plastic. Bearings with a plastic cage have the suffix TV.
