Do you know the structure of needle sleeve bearing?

Structure type of needle sleeve bearing
The needle sleeve bearing consists of a ferrule, a needle roller and a cage. For the same load carrying capacity, the needle bearing has the smallest cross-sectional dimension. The needle sleeve bearing is suitable for high speed, large load and small bearing space. Needle roller bearings, also known as needle rollers, are slender in shape. The shape of the ends of the needle is round, pointed, and concave.

The commonly used needle sleeve bearing has the following structural types:
1. Needle sleeve bearing of the outer ring:
The needle sleeve bearing has two types of perforated type and sealed type. The drawn outer ring needle roller bearing has no inner ring, and the needle roller directly contacts the surface of the shaft, so the machining precision and heat treatment hardness of the shaft should be the same as the inner ring of the bearing. The needled sleeve bearing with retainer is suitable for high speed and heavy load, and is used in gearboxes or textile machinery for machine tools, automobiles and motorcycles. The stamped ferrule needle bearing without cage is filled with needle rollers and is suitable for oscillating working conditions under heavy loads. Such as the frame of the aircraft, the shaft end of the main wing of the missile, and so on.

2, the physical ferrule needle sleeve bearing:
The needle sleeve bearing of the physical ferrule, the commonly used solid ferrule needle bearing is NA type and RNA type. Solid ferrule needle roller bearings are mostly used in machine tools and automobile gearboxes. They have the advantages of small radial section size and large radial load. The standard type of solid ferrule needle roller bearings have cages, so the high speed can adapt to the requirements of machine tools and automobile gearboxes.

3, combined needle sleeve bearing:
The combination needle sleeve bearing is a combination of a solid ferrule needle bearing and a ball bearing and a roller bearing.
4. Needle roller and cage assembly:
The needle roller and cage assembly are actually needle sleeve bearings without ferrules. These bearings are mostly used for connecting rods and small ends of gearboxes, motorcycles and automobiles. Because the internal temperature of the cylinder rises, the bearing is resistant to high temperatures.
