Jiaxing bearing group: combined needle roller bearing related knowledge

There is rotational, have HRB bearing ( ) Jiaxing bearing group: combined needle roller bearing related knowledge. Jiaxing bearing group sales co. , LTD. ( The company) Is in jiaxing bearing group set up by the spot sales window, specializing in HRB brand bearings, existing stocks of 50 million yuan, covers the whole bearing, have very strong cash supply ability. Combined needle roller bearing is a centripetal needle bearing and thrust bearing or bearing unit of angular contact ball bearing components combination, the compact structure small volume, rotation of high precision, high in can bear radial load at the same time absorb a certain amount of axial load. A variety of forms, wide adaptability and product structure, easy to install. Widely used in machine tools, metallurgical machinery, textile machinery and printing machinery. Combined needle roller bearing used in coordinate axis design for bearing raceway, the hardness of bearing certain requirements; Or with the company special IR standard set set of inner ring, and no requirement to shaft stiffness, the structure will be more compact. Widely used in machine tools, metallurgical machinery, textile machinery, printing machinery and other machinery and equipment, and can make the mechanical system design more compact and nimble. Structure form of the class has a centripetal needle bearing and thrust full ball, or thrust cylindrical roller and thrust ball, or with, or combined with angular contact ball, can withstand the one-way or two-way axial load. Can also be designed according to customer's special requirements. Products according to JB/T8877 precision of dimension tolerance and geometric accuracy. Needle roller diameter difference each other in 2 & mu; M, precision grade for G2 level ( Gb GB309) 。 No bearing inner ring inscribed circle diameter in line with the F6 tolerance level before assembly. Bearing radial clearance in accordance with GB/T4604 e. 0 group. According to GB/T307 special precision level. 1. For the bearing clearance, details of the inscribed circle, precision grade special requirements should contact with the company. Material needle for GCr15 bearing steel, hardened HRC6065. Inside and outside the ring material is GCr15 bearing steel, hardened HRC6165. Cage materials for high quality low carbon steel or reinforced nylon. Special instructions NKIA, NKIB series bearing axial load shall not exceed 25% of the radial load. Used in the bearing situation of alternating axial load must be opposed to install. Basic rated thrust bearing parts must be applied to the axial static load's 1% load. When using the plastic cage ( The suffix TN) Continuous working shall not exceed the operating temperature of + 120 & deg; C。 Thrust bearing parts should be free in the bearing seat. General configuration design bearing rolling bearing application technology in the relevant recommendations. Standard GB/T66431996 rolling needle roller bearings and cylindrical roller thrust bearing dimension ( GB - 11) JB/T31221991 rolling bearing needle roller bearing and thrust ball bearing dimension ( JB - 1) JB/T31231991 rolling bearing needle roller bearings and angular contact ball bearings overall dimensions ( JB - 1) JB/T66441993 rolling bearing needle roller dimensions and tolerances and two-way thrust cylindrical roller bearings, JB - 3) JB/T88772001 rolling bearing needle roller bearing combination conditions ( JB - 12) 。 24-hour customer service hotline: if you are more interested in jiaxing bearing group introduced industry information or have any questions, please click on contact us page on the right side of the online customer service, or call:, you close the way of jiaxing bearing purchasing advisors. - - - - - - Editor: HRB bearing company sourcing consultant LTD.
