Bolted roller bearing, outer ring wall thickness, needle roller busbar with convexity, the raceway surface of the stud bolt is hardened, has a certain toughness, and can withstand impact loads. Features of bolted roller bearings: 1. Higher rotational speed 2. Can withstand higher radial loads (larger than other bearings with the same radial size) 3. Cannot withstand axial loads 4. High rigidity combination Bolt roller bearing combination Bolt roller bearing is a bearing unit which is a combination of radial bolt roller bearing and thrust bearing components. It has a compact structure, small volume, high rotation accuracy, and can withstand a certain axial load while bearing a high radial load. And the product structure is diverse, adaptable and easy to install. Combined bolt roller bearings are widely used in machine tools, metallurgical machinery, textile machinery and printing machinery and other mechanical equipment, and can make the mechanical system design very compact and flexible. Bolted roller bearings, also known as curved roller bearings with bolts, are a commonly used structural type of roller bearings. Bolted roller bearings (curved roller bearings) have a thicker outer ring, a thick-walled outer ring with radians, a solid inner ring with a fixed thread on the shaft, and a cage assembly or a full complement of rolling elements. There are single-row and double-row designs, and the load characteristics are the same as those of the support roller bearings. The curved rollers are available with sealed and open type, with eccentric sleeves and without eccentric sleeves.

High rigidity bolts Definition and Origin of Roller Bearings The profile surface of the roller needle is slightly constricted at the proximal face. Roller needle and raceway line contact correction results in bolted roller bearings avoiding damaging edge stresses. Supporting roller bolts The roller bearing is a thick-walled outer ring, which is quenched at high temperature and high nitrogen. The rollers of high-precision sorting are guided by the ribs of the high-rigidity outer ring. Using linear contact, the roller can easily rotate directly on the raceway, and can bear huge loads. In order to remove the stress, the outer ring of the support roller is designed with a curved surface. The bolted roller bearing is equipped with thin and long rollers, so the radial structure is compact. When its inner diameter and load capacity are the same as other types of bearings, the outer diameter is small, which is especially suitable for bearing results with limited radial installation size. Depending on the application, a bearing without an inner ring or a roller needle roller and cage assembly can be selected. At this time, the surface of the journal and the surface of the shell hole matched with the bearing are directly used as the inner and outer rolling surfaces of the bearing. In order to ensure the load capacity and operation The performance is the same as that of bearings with rings. The hardness, machining accuracy and surface quality of the raceway surface of the shaft or housing hole should be similar to the raceway of the bearing ring. This type of bearing can only bear radial loads.
