Product Description PRODUCT DETAILSFull complement needle roller bearings with inner rings are key components of industrial equipment, highly favored for their unique design and excellent performance. Its outer ring is equipped with oil holes and dual gear edges, which facilitate lubrication. The dual gear edges precisely fix the needle rollers, and it is matched with an inner ring without gear edges. The structure is compact and saves radial space. Fully complement needle rollers endow it with strong radial load-bearing capacity, allowing it to withstand larger radial loads at the same size, especially suitable for space limited and heavy load scenarios such as automotive transmissions and industrial gearboxes. However, due to the absence of a cage, its maximum speed is relatively low and not suitable for ultra high speed operation. Strict precision control is required during installation to ensure precise fit between the inner and outer rings and the needle rollers, and high requirements are placed on the surface hardness and roughness of the shaft neck. The inner ring fully complement needle roller bearings provide reliable support for the stable operation of mechanical equipment due to their high load-bearing capacity and space saving advantages.MORE PHOTOSCATALOGUEModeld mmDmmHmmW kgNA49001022130.023NA49011224130.026NA49021528130.034NA49031730130.04NA49042037170.075NA49052542170.099NA49063047170.101NA49073555200.186NA49084062220.249NA49094568220.294NA49105072220.298NA49115580250.393NA49126085250.426NA49136590250.456NA491470100300.728NA491575105300.773NA491680110300.819NA491785120351.25NA491890125351.312NA491995130351.371NA4920100140201.9NA4922110150402.07COMPANY INTRODUCTIONPRODUCTION PROCEDURERELATED PRODUCTSFUNCTIONOUR ADVANTANGE
