Needle roller bearings


Detailed description

Needle roller bearings are cylindrical roller bearings, relative to its diameter, the roller is both thin and long. This roller is called a needle roller. In spite of the smaller cross section, the bearing still has a high load capacity. The needle roller bearings are equipped with thin and long rollers (roller diameter D ≤ 5 mm, L / D ≥ 2.5, L is the roller length) and therefore Radial structure is compact, its inner diameter size and load capacity and other types of bearings the same, the smallest diameter, especially for radial installation size limited support structure. Depending on the use of different occasions, the optional inner ring bearing or needle roller and cage assembly, this time with the bearing surface of the journal and shell hole directly as the bearing inner and outer rolling surface, in order to ensure load capacity and running performance The same with a ring bearing, shaft or shell hole raceway surface hardness, machining accuracy and surface quality should be similar with the bearing raceway raceway. Such bearings can only bear radial load.
Features

Needle roller bearings equipped with thin and long roller (roller diameter D ≤ 5mm, L / D ≥ 2.5, L is the roller length), so the radial structure is compact, its inner diameter size and load capacity and other types of bearings the same , The smallest diameter, especially for radial installation size limited support results. Depending on the use of different occasions, the optional inner ring bearing or needle roller and cage assembly, this time with the bearing surface of the journal and shell hole directly as the bearing inner and outer rolling surface, in order to ensure load capacity and running performance The same with a ring bearing, shaft or shell hole raceway surface hardness, machining accuracy and surface quality should be similar with the bearing raceway raceway. Such bearings can only bear radial load.
