YRT bearing consist of a thrust/radial housing washer, a thrust/radial shaft washer, a thrust washer, two Axial needle roller and cage assemblies and a group of radial cylindrical roller . housing washer and shaft washer have bolt hole for install equally spacer. This kind of bearings have high axial load and radial load ,and high tilting rigidity and high precision. This bearing can be used to the machine tool or other high precision machinery of the rotary table or sub-set, and also can be used for chuck, measuring instruments and test equipment,and rotary table configuration. This bearing request higher quality of the parts match lt. You must control screw tightening torque when install it. YRT series rotary bearings at the precision level of P4, P2, YRT50 YRT80 YRT100 YRT120 YRT150 YRT180 YRT200 YRT260 YRT325 YRT395 YRT460 YRT580 YRT650 YRT850 YRT950 YRT1030 SKFNSK INDUSTRIAL LIMITED ADD: No.198 CAO GANG ROAD LINQING CITY SHANDONG CHINA TEL: 0086-635-2688128 FAX: 0086-635-2325139 EMAIL: info@skfntn.com skfnsk8@gmail.com MSN: skfntn@hotmail.com WEB: http://www.skfntn.com
