Do you know the applications of drawn cup roller clutches?

drawn cup roller clutches 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 drawn cup roller clutches. The small diameter is especially suitable for support results with limited radial mounting dimensions. Depending on the application, bearings or needle roller and cage assemblies without inner ring can be used. The journal surface and the housing hole surface that match the drawn cup roller clutches directly serve as the inner and outer rolling surfaces of the bearing to ensure load capacity and running performance. As with ferrule bearings, the hardness of the raceway surface of the shaft or housing bore, the machining accuracy and surface quality should be similar to the raceway of the bearing ring. This type of bearing can only withstand radial loads.

The drawn cup roller clutches has various structural forms and the applicable scope is also as follows:
Needle roller bearings for drawn outer rings. The 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 drawn cup roller clutches.

Scope of application: The drawn cup needle roller bearing with cage is suitable for high speed and heavy load, and is mostly used for gearbox or textile machinery of 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.

Solid ferrule drawn cup roller clutches. Commonly used solid ferrule needle bearings are type NA and RNA. Scope of application: It is mostly used in machine tools and automobile gearboxes. It has the advantages of small radial section size and large radial load. Standard solid ferrule needle bearings have cages, so the high speed can adapt to the requirements of machine tools and gearboxes.

drawn cup roller clutches are applicable to printing machinery, pasture machinery, agricultural machinery, roller for CNC equipment guide rails, conveyor lines, etc.

Needle roller and cage assembly. The needle roller and cage assembly are actually drawn cup roller clutches without ferrules. Scope of application: It is mostly used for large and small ends of connecting rods for automobiles and motorcycles. Because the internal temperature of the air box rises, the drawn cup roller clutches is resistant to high temperatures.
