The outer ring is intended to be stationary, with only the inner ring actually moving. This type of bearing is well balanced and typically delivers long service cycles without a great deal of user maintenance we also manufactures precision cylindrical rollers and needle rollers according to customer's ● home ● products ● contact ● equipments ● steel balls ● capillary tubes ● cylindrical roller ● needle rollers ● sizes or stocks ● D0.5, D0.6, D0.7, D0.8, D0.9 ● D1.0, D1.1, D1.2, D1.3, D1.4 ● D1.5, D1.6,D 1.7, D1.8, D1.9 ● D2.0, D2.1, D2.2, D2.3, D2.4 ● D2.5, D2.6, D2.7, D2.8, D2.9 ● D3.0, D3.1, D3.2, D3.3, D3.4 ● D3.5, D3.6, D3.7, D3.8, D3.9 ● D4.0, D4.1, D4.2, D4.3, D4.4, D4.5, http://www.bearing-needle.com/4mini-shafts-D4...8-D4L25.8-D4L27.8-D4L29.8-D4L34.8-D4L39.8.htm(第 1/3 页)[2015-11-11 13:43:19]
