SKF combined needle roller bearings include needle roller/angular contact ball bearings, needle roller/thrust ball bearings, needle roller/cylindrical roller thrust bearings. The combined needle roller bearings can accommodate both radial and axial loads. 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. Today, I’d like to introduce SKF needle roller/angular contact ball bearings to u. Needle roller / angular contact ball bearings combine a radial needle roller bearing with a radial angular contact ball bearing to produce a low cross section bearing that can operate at high speeds and accommodate heavy radial and light axial loads. The radial loads are accommodated exclusively by the needle roller bearing. has been engaging in dealing with SKF bearings since our company was founded. Therefore, we have gained a great many of experience on SKF bearings during years’ hard-working efforts. We have already extended our customers to India, Thailand, Turkey, Pakistan, Israel, Oman, Spain, Malaysia, Singapore, Vietnam, Tanzania, Tunisia, UK, USA, Greece, Peru, Canada and so on. Superior to other suppliers, we can offer SKF bearings at cheapest price based on the datasheet and certificates and punctual delivery time. If u have any requirements for SKF bearings, please don't hesitate to contact me.
