Combined needle roller bearing product precision scale public service and a few precision according to JB/T8877. Needle diameter difference between each other is 2μm; accuracy grade is G2 grade (national standard GB309). No inner ring bearing before installation, the inscribed circle diameter fits the public service grade F6 The radial clearance of the bearing fits the specified value of the GB/T4604 group of 0. The special accuracy grade is in accordance with GB/T307. 1. For details of the special requirements of bearing clearance, inscribed circle and accuracy grade, please contact the company.
Combined needle roller bearing work data needle roller data for GCr15 bearing steel; hardened HRC60-65. Inner and outer ring data for GCr15 bearing steel; hardened HRC61-65. Cage information for high quality low carbon steel or reinforced nylon.
Combined needle roller bearings require a combination of needle roller bearings to be used as bearing raceways at the cooperating shaft; there is a certain requirement for the hardness of the bearing, or with the inner ring of the IR specification for sheathing; there is no need for shaft hardness; the layout will be more compact .
