The combined needle roller bearing is a bearing unit consisting of a combination of a radial needle roller bearing and a thrust bearing or an angular touch ball bearing component; its layout is compact and compact. The gar is slightly smashed and smashed.蚋汉. And the product layout is diverse, adaptable, easy to install. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
Widely used in machine tools, metallurgical machinery, textile machinery and printing machinery.
First, the layout method <br> This type of bearing has a centripetal needle and thrust full ball, or with a thrust ball, or with a thrust cylindrical roller, or with the angular touch ball as one; can accept one-way or two-way axial Load. It can also be drawn according to the user's special layout requirements.
Second, the product accuracy <br> Scale public service and a few precision according to JB/T8877.
The needle diameters are different from each other by 2μm; the accuracy grade is G2 (GB309).
The inner diameter of the inner ring bearing without the inner ring bearing fits the public service grade F6.
The radial clearance of the bearing fits the specified value of group 0 of GB/T4604.
Special accuracy grade according to GB/T307.1.
Third, the information <br> Needle roller information is GCr15 bearing steel; hardened HRC60 65.
The inner and outer ring data is GCr15 bearing steel; hardened HRC61 65.
Cage information for high quality mild steel or reinforced nylon
