Zhenghe people since 1990 bearing practitioners to the diligent and pragmatic spirit of pioneering ZARF1560LTN needle roller bearings, to create a governance today's performance. Now governance and needle roller bearings company has sophisticated production equipment ZARF1762LTN needle roller bearings, perfect detection means ZARN1747LTN needle roller bearings, strong technical force, "to the credibility of development, quality of survival" purposes. Needle bearing fitted thin and long rollers (roller length of 3 to 10 times the diameter of the needle roller bearings, diameter is generally not more than 5mm), so the radial structure is compact, its diameter size and load capacity with other types of bearings, minimum diameter , especially for radial bearing installation dimensions restricted ZARN1545TN needle bearings, combined (certified), needle roller bearings supplied by Linqing municipal and needle roller bearings plant.
