Needle roller bearings are rotary motion bearings with needle-shaped thin-walled rollers as rolling elements. Consists of a machined outer ring and needle rollers that are caged and guided. Their low cross-section height and large load capacity compared to ball bearings help make machines smaller and lighter.
Our product range includes machined needle roller bearings, drawn outer ring needle roller bearings, spherical needle roller bearings, inner rings, thrust needle roller bearings, cam followers, cam rollers, needle roller cages, needle roller thrust bearings and thrust washers.
Features
1. Compact radial structure
Needle roller bearings have the characteristics of compact radial structure and can take advantage of mechanical products with small radial space.
2. Larger load intensity
At present, many mechanical products are becoming smaller and more precise. Needle roller bearings are made of high-quality materials, and their structure is very suitable for small spaces. In the same radial size, the load capacity of needle roller bearings is relatively large.
3.Long service life
When producing needle roller bearings, high-hardness alloy materials are generally used to enhance their strength and load capacity, so that the needle roller bearings can achieve a longer service life.
As machine components, they help save space by making the entire machine compact. Application scenarios of needle roller bearings include:
1. Automobiles: Needle roller bearings can be used in automobile torque converters, gearboxes, suspensions and other components to improve the performance of the automobile.
2. Machine tools: Needle roller bearings can be used in gear boxes, spindles, tool magazines and other components of machine tools to improve their accuracy and stiffness.
3. Metallurgy: Needle roller bearings can be used in coilers, rolling mills, shears and other components of metallurgical machinery to improve the efficiency and safety of metallurgical machinery.
4. Printing: Needle roller bearings can be used in paper cutters, turntables, folding machines and other components of printing machinery to improve their accuracy and stability.
