Long-term performance depends on proper pin bearing maintenance. These bearings are likely to fail over time due to the high level of friction between the ring and the pin. Many pin bearings are self-lubricating, which helps to reduce friction automatically. Others must be lubricated often to minimize stress and friction. Pin bearings must also be cleaned regularly to prevent dirt and grease from building up and interfering with performance. 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. the parameters is one of stock for diameter 0.5 to diameter 1,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 can production ultrafine needle rollers,such as:D0.45, D0.4, D0.3,D0.35 etc. but material is stainless steel 304,201. can not hardened. ● 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, D4.6, D4.7, http://www.bearing-needle.com/0.5needles-D0.5-D0.6-D0.7-D0.8-D0.9.htm(第 1/3 页)[2015-10-17 22:19:25]
