Needle bearings of UQG

Needle roller bearings are roller bearings with cylindrical rollers, which are both thin and long relative to their diameter. Despite having a smaller cross-section, bearings still have a higher load-bearing capacity. Needle roller bearings are equipped with thin and long rollers, resulting in a compact radial structure. Their inner diameter size and load capacity are the same as other types of bearings, while their outer diameter is the smallest, making them particularly suitable for support structures with limited radial installation dimensions.

This type of bearing has no retaining edge on the inner ring, so the outer ring and inner ring can be installed separately. It cannot limit the axial displacement of the shaft and shell, and can only withstand radial loads. This type of bearing ring usually does not have lubrication holes. If the user has requirements, oil holes can be machined on the outer or inner ring. After high-temperature tempering treatment, the various components of this type of bearing can be used normally at a temperature of 300 ℃.
