Characteristics and advantages of FTM needle roller bearing with inner ring
1. No need to process the shaft raceway: the design of the inner ring makes the ordinary untreated shaft can be used directly, reducing the processing complexity and cost.
2. High carrying capacity: the length to diameter ratio of the needle roller is large, the contact area is large, and it can withstand high radial load.
3. Compact design: suitable for radial space limited occasions, small volume but strong bearing capacity.
4. Strong flexibility: needle roller bearings with inner rings are suitable for scenes where the shaft surface is irregular or cannot be finished.

Application scenario of FTM needle roller bearing with inner ring
1. Automobile industry
Gearbox, drive shaft, clutch assembly.
Rocker arm shaft, valve tappet and other parts.
2. Industrial machinery
Packaging equipment, textile machinery, mining machinery.
Compact bearing applications in pumps and compressors.
3. Power tools
High load and high speed bearings in hand tools.
4. Agricultural machinery
Linkage transmission system, planter, harvester.
5. Other areas
Aviation equipment, robot joints, hydraulic machinery.
