NU The rollers are guided by a cage in the outer ring between two flanges. The inner ring is made without guide flanges, which allows axial sliding of the rings between each other. NJ Like the NU version, but the inner ring has a guide flange on one side. It can transmit unilateral axial force. NUP The outer ring is in a version with two guide flanges, the free inner ring has a fixed flange on one side, a flat flange is added on the other side. These bearings can be used to transmit bilateral axial forces. MAIN DIMENSIONS The main dimensions of the roller bearings are given in the dimension tables and correspond to the international standard ISO 15. www.zvlslovakia.sk 119 N The rollers are guided by a cage on an inner ring fitted with two fixed flanges. The outer ring is without guide flanges. Relative axial displacement of the rings is possible. NF Inner ring with two fixed flanges, outer ring with one guide flange. HJ thrust rings, which can be used to ensure the transmission of axial forces from the desired direction. Possible combinations of the HJ thrust ring with bearings: NJ+HJ, NU+HJ We do not recommend the combination of the NU bearing with two HJ thrust rings, as axial pinching of the rollers may occur. The illustration of the individual designs is above the tabular section.
