high-precision cylindrical rollers can be used in various types of robots, where precision and accuracy are critical factors for their performance. Cylindrical rollers can be used in robotic applications in several ways, such as in robot joints, linear actuators, and other motion control mechanisms. 18x18,18x26,19x20,20x20,21x2,22x22, 22x34,

Robotic joints often require high-precision cylindrical rollers to achieve smooth and precise motion and positioning. These rollers can be used in both rotary and linear joints to provide low-friction, high load capacity, and precise positioning. High-precision cylindrical rollers can also be used in linear actuators, which convert rotational motion into linear motion, to achieve high-speed, high-precision motion in a compact design.

cylindrical rollers can be used in joint bearings, which are a type of plain bearing designed to accommodate both radial and axial loads. Joint bearings, also known as spherical plain bearings or plain spherical bearings, typically consist of an inner ring, an outer ring, and a sliding layer between them, which may include cylindrical rollers or other types of rolling elements.

Cylindrical rollers are commonly used in joint bearings where the load capacity and wear resistance of the bearing are critical factors. The cylindrical rollers can be arranged in a variety of configurations, such as parallel or crossed, to suit the application and the desired load-bearing capacity

the ends of needle rollers had different types: such as:NRA (round ends), NRB (flat ends), crowned ends, pointed ends, or one end is round(pointed), the other end is flat etc.

Joint bearings with cylindrical rollers can be used in a wide range of applications, including construction equipment, mining machinery, and heavy-duty transportation, where they can provide high load-bearing capacity and long service life. However, the selection of the right type of joint bearing depends on several factors, such as the load conditions, the speed of operation, and the environmental conditions, and requires careful consideration of the specific application requirements.
