precision needle rollers have multiple uses in a variety of applications. Needle rollers are mainly used as bearing rolling elements to transmit torque and reduce friction. They can also serve as precision shafts or as precision locating pins. Needle rollers with a controlled contour profile are available to reduce end stresses. special end forms provide performance benefits for specific kinds of applications.

needle rollers are long, thin cylindrical rollers with a high length-to-diameter ratio. They are typically used in applications where space is limited and a high load-carrying capacity is required. Needle rollers are commonly used in automotive and industrial applications, such as transmissions, engines, and textile machinery.

cylindrical rollers(regulation values,tolerance, grade, changes of length volume quantities, length gauge value spacing, face runout value. needle rollers are designed to handle high radial loads with a small cross sectional profile, needle rollers are used to transmit power or motion between two or more components.
