cylindrical rollers can be used in cross bearings. Cross bearings, also known as crossed roller bearings or crossed roller slides, are commonly used in applications that require high precision and stiffness, such as machine tools, robotics, and medical equipment.8x8,8x10,9x9,9x14,

In a cross bearing, two sets of cylindrical rollers are arranged at right angles to each other and placed between two parallel guide rails. The rollers are typically made of high-strength bearing steel and are preloaded to ensure consistent contact between the rollers and the guide rails. The design of the cross bearing allows it to accommodate both radial and axial loads, as well as moments about both axes.

The use of cylindrical rollers in cross bearings provides several benefits, including high load capacity, high stiffness, and smooth and accurate motion. The cylindrical rollers can also withstand high speeds and accelerations, making them suitable for high-performance applications.

The selection of the appropriate cylindrical roller size, material, and accuracy depends on the specific requirements of the cross bearing and the application. The load capacity, precision requirements, and environmental conditions of the application are important factors to consider when selecting cylindrical rollers for use in cross bearings.

It is widely used in auto, lathe, metallurgical, textile, printing industry & other various machinery equipment. With this kind of bearing, machine design can realize the goal of small-scale & lightweight.

needle roller contour surface in the proximal surface of the slight contraction. needle and raceway contact line results can be amended to avoid damaging the edge of the stress.

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.

needle rollers main use is as rolling elements in bearings where they are particularly useful when space is limited and a high radial load is required. They are also useful as locating pins and mini shafts.
