Combined radial and thrust bearing:1.It features compact structure 2.small size and high rotating accuracy
Types of Designs:This kind of bearing is a combination unit between radial needle rollers and full-component thrust balls, thrust cylindrical rollers or otherwise angular contact balls. It can bear one-way or two-way axial load. Special structure can be designed as well according to the requirements of customers.Product Precision Accuracy:Dimensional tolerance and geometrical accuracy is based on JB/T8877.Mutual difference of needle roller diameter is 2μm, and the precision grade is G2 (ISO GB309).The diameter of inscribed circle conforms to tolerance grade F6 before the fitting of outer ring with cage and roller assembly.Bearing radial running clearance conforms to the value defined by 0 group of GB/T4604.Special accuracy grade is based on GB/T307.1For fuller information on the special requirements of bearing running clearance, inscribed circle and accuracy grade, please contact this company.
Materials:Material for needle roller is GCr15 bearing steel, quench-hardening HRC60---65.Material for inner and outer races is GCr15 bearing steel, quench-hardening HRC61---65.Material for cages is quality low-carbon steel or reinforced nylon.Special Directions:Axial load of NKIA, NKIB series of bearings is not allowed to exceed radial load by 25%.Being used for supporting alternative radial load, it must be installed in opposition.Thrust bearing parts must exert preload up to 1% of axial basic rated static-load.When plastic cages are used (suffixed with TN), operating temperature is not allowed to surpass +1200C during continuous work.Thrust bearing parts can move freely in bearing bracket.For general-disposition design of bearings, refer to the relevant recommendation in the applied technology of rolling bearings.
