RBC bearing

Needle roller bearings are equipped with thin and long rollers (the length of the roller is 3 to 10 times the diameter and the diameter is generally not more than 5 mm), so the radial structure is compact, and the inner diameter and load capacity are the same as those of other types of bearings. The smallest diameter, especially suitable for radial mounting size limited support structure. Needle roller bearings can be selected according to different applications, the inner ringless bearing or needle roller and cage assembly, the journal surface and outer casing matched with the bearing The surface of the hole directly serves as the inner and outer rolling surface of the bearing. To ensure the load capacity and running performance, the hardness of the raceway surface of the shaft or the outer casing hole is the same as that of the ferrule bearing. The machining accuracy and surface quality should be combined with the bearing ring. The needle bearing is a bearing unit composed of a combination of a radial needle roller bearing and a thrust bearing component. The compact structure is small, the rotation precision is high, and it can withstand a certain axial load while receiving a high radial load. And the product structure is diverse, adaptable and easy to install. Combined needle roller bearings are widely used in various mechanical equipment such as machine tools, metallurgical machinery, textile machinery and printing machinery, and can make the mechanical system design very compact and dexterous.
