Stainless steel needle roller refers to the rotating body on the stainless steel needle roller bearing. It is mainly used in various types of bearings. It is a roller bearing with cylindrical rollers. The rollers are thin and long like needles. This kind of bearing has a higher load. Bearing capacity. The radial structure is compact.
Structure type of stainless steel needle roller
Stainless steel needle roller bearings are composed of ferrules, stainless steel needle rollers and cages. In terms of the same load capacity, the cross-sectional dimension of the stainless steel needle roller bearing is the smallest. It is suitable for occasions with high speed, large load and small bearing space. Stainless steel needle roller bearings, also known as needle rollers, have a slender shape. The shape of both ends of the stainless steel needle roller has round head, pointed cone, and concave arc head.
Commonly used stainless steel needle roller bearings have the following structural types:
1. Stainless steel needle roller bearings with stamped outer ring:
This kind of bearing has two types: perforated type and sealed type. The stamped outer ring stainless steel needle roller bearing has no inner ring, and the stainless steel needle directly contacts the surface of the shaft. Therefore, the machining accuracy and heat treatment hardness of the shaft should be the same as the inner ring of the bearing. Stainless steel needle roller bearings with a cage with a stamped outer ring are suitable for high speed and heavy loads, and are mostly used in gearboxes for machine tools, automobiles, and motorcycles or textile machinery. The stamped ferrule stainless steel needle roller bearing without cage, because it is filled with stainless steel needle roller, is suitable for swing working conditions under heavy load. Such as the frame of the aircraft, the shaft end of the main wing of the missile, etc.
2. Entity ferrule stainless steel needle roller bearings:
Stainless steel needle roller bearings with solid ferrules. Commonly used stainless steel needle roller bearings with solid ferrules are NA type and RNA type. Solid ferrule stainless steel needle roller bearings are mostly used in machine tools and automobile gearboxes. Its advantages are small radial section size and large radial load. Standard type solid ferrule stainless steel needle roller bearings have cages, so the speed is higher, which can meet the requirements of machine tools and automobile gearboxes.
3. Combined stainless steel needle roller bearings:
Combined stainless steel needle roller bearings are a combination of solid ring stainless steel needle roller bearings, ball bearings and roller bearings.
4. Stainless steel needle roller and cage components:
Stainless steel needle roller and cage components are actually stainless steel needle roller bearings without ferrules. This type of bearing is mostly used for the large and small ends of the connecting rods of gearboxes, motorcycles, and automobiles. As the temperature in the cylinder rises, the bearings must be resistant to high temperatures.
