the rollers in a needle roller bearing can vary depending on application. some variations include tapered rollers, crowned rollers

the use of needle rollers in bearings allows for a high load capacity in a small space, making them ideal for applications with limited radial space, such as transmissions, engines, and textile machinery. needle roller bearings can also be used in applications where high accuracy and rigidity are required, such as machine tools and robotics.

we have over 20 years of manufacturing experience of precision rolelrs. we had most stock, delivery time: send to europe, USA, or canada only 3-5 work days

the shape and size of the rollers in a needle roller bearing can vary depending on the specific application and design requirements. some variations include tapered rollers, crowned rollers, and rollers with special surface coatings or treatments to enhance their performance.

In summary, while both cylindrical rollers and dowel pins are cylindrical components, they are used for different purposes and have distinct design characteristics. Needle rollers are commonly made from materials that are hardened and ground to improve their strength, durability, and wear resistance. Hardening is the process of heating the material to a high temperature and then rapidly cooling it (quenching) to produce a hard surface layer..

the rollers in a needle roller bearing are cylindrical rollers with a high length to diameter ratio. they are typically made of hardened and ground steel or other materials, and are designed to provide high load-carrying capacity and low friction. the rollers are arranged in a cage or retainer, which holds them in position and maintains the spacing between them.

we are professional manufacture of bearing rollers and cylindrical needle rollers. we produce rollers of diameter 0.5 mm to 60 mm. the rollers could satisfy the request of DIN 5402 G2 rollers.
