Needle roller bearings have several common applications where their characteristics are well suited:
High speed applications.
Needle roller bearings can operate at very high speeds with minimal friction and heat generation. They are often used in applications like:
Spindles and spindle nodes in lathes, milling machines and grinding machines.
Small electric motors, fans and blowers.
Turbochargers, superchargers and other forced induction components.
Applications with high axial loads.
Needle roller bearings can handle substantial axial loads in addition to radial loads. They are used in:
Drawer slides, rack rails and drawer pull slides.
Actuators, jacks, hoists, lifts and auto parts like alternators.
Chain hoists, crane hooks, monorail hangers and chainfalls.
Applications with oscillating or eccentric motion.
The small size and shape of needle rollers allows smooth motion in applications with oscillating, pivoting or eccentric movement. Uses include:
Knife blades, scissors, cutters, guillotines and woodturning tools.
Rod ends, tie rods, push rods and control rods.
Pendulum wirings, vibrating screens and conveyors.
Applications in tight spaces.
Needle roller bearings have an extremely compact design that performs well even with limited space. They are used in:
Small pulleys, sheaves, wheels and rollers.
Slides and ways in micrometers, calipers and comparators.
Hinges and pivots in jewelry, clasps, locks, lamps and watches.
High load and weight applications.
Despite their small size, needle roller bearings can support significant loads relative to their size. Common uses include:
Axles, joints, linkages, toggles and cam followers.
Tools like taps, feeler gauges, depth gauges and scribers.
Push rods and pull rods under heavy loads.
Drawbar guide systems in large hot and cold presses.
Large electric motors, industrial air motors, fans and blowers.
In china Needle Roller Bearings suppliers manufacturers summary, needle roller bearings serve well in high speed, high load, high precision and space constrained applications. They provide smooth, efficient and long-lasting motion in a wide range of mechanical engineering components, tools, equipment, vehicles and machines. When small size, light weight and durability are required, needle roller bearings enable optimized performance and part life.
