In these cases the bearing needles run directly on the shafts surface. these running surfaces, however, must to be designed to the same quality standard as for bearing rings,. since needle roller bearings allow for length compensation of a certain amount within the bearing, they are optimum as non locating bearings. 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 5(mm) series: dowels, rollers and pins,cylindrical rollers and needle rollers ● 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, http://www.bearing-needle.com/5x5+5x10+cylin...x25.8+5x27.8+5x29.8+5x34.8+5x39.8+5x49.8.htm(第 1/2 页)[2016-1-29 0:04:52]
