Needle roller bearings are a type of rolling element bearing that uses long and thin cylindrical rollers instead of balls. These rollers have a high length-to-diameter ratio and can support radial loads, making them suitable for use in a variety of industrial applications. Needle roller bearings are typically used in applications where space is limited, and high load-carrying capacity is required. They are commonly used in automotive and aerospace applications, as well as in various types of machinery, such as gearboxes, engines, and pumps.

A cylindrical roller is a cylindrical shaped rolling element used in cylindrical roller bearings, which is designed to reduce friction and handle high radial loads. In contrast, a cylindrical pin is a solid cylindrical rod used as a mechanical fastener, pivot or connector.

The primary differences between a cylindrical roller and a cylindrical pin are their intended applications and the way they are used. Cylindrical rollers are used in rotary applications to reduce friction between rotating parts, while cylindrical pins are used in static or dynamic mechanical connections to hold two or more parts together, pivot or transfer force between them. <

A cylindrical roller is a cylindrical-shaped rolling element that is used in cylindrical roller bearings to reduce friction and handle high radial loads in rotary applications. In contrast, a dowel pin is a solid cylindrical rod that is used as a precision alignment or locator component to maintain the relative position of two or more parts in a static or dynamic connection.

The primary difference between a cylindrical roller and a dowel pin is their intended function and the way they are used. Cylindrical rollers are designed to reduce friction between rotating parts and to transfer loads between them, while dowel pins are designed to locate and align parts and prevent unwanted movement or misalignment.

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.
