1.NA4848 high quality needle roller bearings
2.size:240*300*60mm,weight:11kg
3.series: NA,NKI,RNA,NK,HK,BK
4.type: (1), enclosed drawn cup needle roller bearings (2), with inner ring needle roller bearings (3) and has no inner ring needle roller bearing/no inner ring no cage needle roller bearings (4), a cage and no cage full of needle roller bearings (5) SKF can also supply various types of needle roller bearing, 1, needle cage component 2, no guard needle roller bearing 3, 4, combination self-aligning roller/ball bearing 5, the combination of the needle/thrust ball bearing 6, the combination of the needle/cylindrical roller thrust bearing
5.charactor : Needle bearing with fine and long roller (roller diameter D quartile 5 mm, L/D was 2.5, L for roller length), so the radial compact structure, its inner diameter size and loading capacity and other types of bearing phase at the same time, the minimum diameter, especially suitable for radial installation size restricted bearing results.
