The flat bearing consists of a flat cage assembly with a needle roller or a cylindrical roller and a flat washer. Needle rollers and cylindrical rollers are held and guided by flat cages. When used with different series of DF flat bearing washers, many different combinations of bearing arrangements are available. Because the high-precision cylindrical roller (needle needle) is used to increase the contact length, this bearing can obtain high load capacity and high rigidity in a small space. Another advantage is that if the surface of adjacent parts is suitable for the raceway surface, the gasket can be omitted, which can make the design compact. The cylindrical surface of needle rollers and cylindrical rollers used for DF flat needle roller bearings and flat cylindrical roller bearings is Shaped surface can reduce edge stress and improve service life.

Plane needle roller and cage assembly AXK

The flat needle roller and cage assembly is the main component of the flat needle bearing. The roller needles are held and guided by a radially arranged pouch. The cross section of the cage has a specific shape and is formed from a hardened steel strip. The small size cage is made of industrial plastic. Zh

The grouping tolerance of the high-precision needle diameter is 0.002mm, which ensures a uniform load distribution. The flat needle roller and cage assembly is guided by a shaft. In this way, a relatively low peripheral speed can be obtained even when the surface is guided at high speeds. Zh

If the surface of the adjacent part is designed as a raceway surface to eliminate the gasket, a particularly space-saving support can be obtained. If such a solution cannot be implemented, under the condition of sufficient support, the use of thin-walled steel AS series gaskets can also make the design compact.

Flat cylindrical roller bearings 811, 812, 893, 874, 894

This bearing is composed of a flat cylindrical roller and cage assembly, a bearing seat positioning ring GS and a shaft positioning WS. Flat cylindrical roller bearings in the 893, 874 and 894 series can be used for higher loads. Zh

The cage of flat cylindrical roller bearings can be stamped from high-quality steel plates, and can also be made of industrial plastics, light metals, and brass, etc. Users request according to the use environment.
