Needle roller bearings use long, slim rollers, the so called "bearing needles" as rolling elements. Due to the possibility of mounting inner and outer rings of needle roller bearings separately, mounting becomes much simpler, even under the conditions of mass production. The comparatively thin - walled needle roller bearing rings are usually mounted with tight fits. we supply high quality rollers with hardened steel,all of the rollers had hardened. usually, the material of needle rollers and cylindrical rollers, is chrome steel 52100(HRC60-65) or stainless steel 420 (HRC53-56), the material of balls, is stainless steel 440C(HRC55-58). in both inch and metric sizes. we also custom manufacture special dowel pins to your specification, and will be pleased to offer our quotation upon receipt of your detailed requirements. more stock,such as diameter 2,3,4,5,6,7,8,8,10 (mm)etc. please E-mail to us. for continuously updating every day, any detail of the rollers, please send E-mail to us. we also manufactures precision cylindrical rollers and needle rollers according to customer's drawing. stock of diameter 2(mm) series cylindrical rollers and needle rollers loose needle rollers, precision rollers,cylindrical pins, ● home ● products ● contact ● equipments ● steel balls ● capillary tubes ● cylindrical roller ● needle rollers ● ceramic rollers ● Si3N4 rollers ● ZrO2 rollers ● sizes or stocks ● D0.5mm series ● D1.0 series ● D1.5 series ● D2.0 series ● D2.5 series ● D3.0 series ● D3.5 series ● D4.0 series ● D5.0 series ● D6.0 series ● D7.0 series ● D8.0 series ● D9.0 series ● D10.0-D60.0 series ● 2x2, 3x3, 4x4, 5x5, http://www.bearing-needle.com/2.5x13.8+ZrO2+r...x15.8+2.5x17.8+2.5x19.8+2.2x21.8+2.5x23.8.htm(第 1/2 页)[2015-12-23 1:37:29]
