YDTech® manufacturer of precision combined needle roller bearings! supplier of loose ball roller bearing assemblies in china.

What's combined roller bearings?

combined roller bearing is one assembly combining three components: radial bearing - rolls on the flanges of profiled steel channel axial bearing - rolls on web of profiles steel channel. stub axle - holds both bearings and provides an easy welding point.

combined type needler roller bearings are combinations of a radial bearing and a thrust bearing. baged needle roller bearings are used as radial bearings and thrust ball bearings or thrust roller bearings are used as thrust bearings. they are compact and very economical, and can be subjected to radial loads and axial loads simultaneously. They are widely used for machine tools, textile machinery, and industrial machinery.

combined needle roller bearings consist of a radial needle roller bearing combined with a thrust bearing and are consequently able to accommodate both radial and axial loads. combined needle roller bearings provide the means to produce locating bearing arrangements where radial space is limited.

combined needle roller bearings consist of a radial needle roller bearing combined with a thrust bearing and are consequently able to take up both radial and axial loads. combined needle roller bearings provide the means to produce locating bearing arrangements in a minimum of radial space. They are particularly useful where the axial loads are too heavy, speeds too high, or lubrication inadequate for simple thrust washers to be suitable, and other types of locating bearing take up too much room.

they are particularly suitable for applications where other types of locating bearings occupy too much space, or where the axial loads are too heavy, the speeds are too high, or the lubricant is inadequate for simple thrust washers.
