For rotary tables, machine tool axes and similar setups, the HIWIN CRBB series is a crossed roller bearing: cylindrical rollers sit at 90 degrees to one another along a single raceway. That layout lets the bearing take radial loads, axial loads and tilting moments while keeping deformation low, which is what precision positioning depends on.

Reading the CRBB code is straightforward once you know the pattern. CRBB identifies the crossed roller bearing family. The digits after it come in two groups: the first group gives the bore diameter, the second gives the width or section. That is why CRBB 03010, CRBB 05013 and CRBB 08013 all belong to the same type but differ in size. When you ask for a quote, send the full code as it appears on your drawing or on the bearing itself.

Typical applications include rotary tables on machining centers, milling heads, robot axes, welding positioners, inspection and measuring tables, and laser or plasma cutting machines. In these setups the bearing often turns slowly, but the demands on rigidity and repeatability are high, and it has to handle combined loads.

Selection comes down to the radial load, the axial load and the tilting moment the bearing will see, plus the bore diameter and width your equipment allows. During mounting, the support surfaces need to be flat and parallel, with the preload or clearance specified by the manufacturer and lubrication suited to the speed and the environment. Shaft-to-housing alignment matters: any deviation affects both service life and assembly precision.

Crossed roller bearings are interchanged between brands by matching dimensions and load capacity, not by the commercial code. If you are replacing a bearing from another brand or one without identification, sending the main dimensions and a photo is the most practical approach. We can point you to the compatible alternative and quote the exact code or size you need.

If you already have the CRBB code from your equipment, send it by WhatsApp or email and we will prepare your quote. If you only have the size or the original part, we can also help you identify the corresponding crossed roller bearing.
