Needle bearing

Performance advantages of needle roller bearings

High load-bearing capacity: Numerous needle roller and wire contact methods enable needle roller bearings to withstand large radial loads, making them suitable for applications that require heavy loads.

Small footprint: The compact structure allows it to provide high load-bearing capacity even with limited radial dimensions, effectively saving equipment installation space.

High rotational accuracy: The needle rollers of the needle roller bearing can roll accurately in the raceway under the guidance of the cage, ensuring the rotational accuracy of the bearing and suitable for equipment with high requirements for rotational accuracy.

Low friction coefficient: The rolling friction between the needle roller and the raceway is small, which can reduce energy loss, improve equipment transmission efficiency, and also help reduce bearing heating and wear.

application area 

The automotive industry has a wide range of applications in the engine, transmission, wheel hub, and other parts of automobiles. For example, the piston pin bearings of the engine, synchronizer bearings of the transmission, and wheel hub bearings, as well as needle roller bearings, can withstand large loads in limited space to ensure the normal operation of automotive components.

Industrial machinery: Needle roller bearings are commonly used in various types of machine tools, textile machinery, printing machinery, and other industrial equipment that require high-precision rotation and withstand large radial loads. The spindle of machine tools, roller bearings of textile machinery, etc. can improve the machining accuracy and operational stability of equipment.

Electric tools: Electric tools such as drills and chainsaws have high performance requirements for bearings due to their small size and high power. The compact structure and high load-bearing capacity of needle roller bearings enable them to meet the working requirements of electric tools when rotating at high speeds and withstanding large torques.

Aerospace: Needle roller bearings also play an important role in key components such as aircraft engines and landing gear. Its high reliability, high precision, and lightweight characteristics can meet the strict requirements for components in the aerospace industry.
