Curve wheel bolts for the raceway part of it is through hardened. To avoid stress concentration NATRD35 needle bearings, roller thick arc-shaped outer surface of the loop. Curve wheel there with a single, double ring, without the ring, with a variety of sealing ring models. Grease a large storage space with a ring, providing long-term lubrication NATR35 needle roller bearings, and extended lubrication intervals. N220 or PTFE seal material for its operating temperature ranges of -30 ° C to + 100 ° C or -30 ° C to + 180 ° C. Curve wheel mounted dense it can withstand heavy loads, but the speed is low NATR30 needle roller bearings, and must be constantly re-lubrication. LR inner ring (the ring) IR tolerance value is greater than the inner, end without grinding, lower prices, often with Needle roller bearings used in conjunction. IR Code bearing structural features dimensional tolerance standard LR dimensional tolerances greater than IR. NATR20 needle roller bearings Needle roller bearings _ _ Needle by LINQing municipal governance and needle roller bearings plant. Linqing municipal and needle roller bearings plant (www.zhgzzc.com) strong, credible, in other industries, Liaocheng accumulated a large number of loyal customers. The company better work attitude and constantly improve governance and innovative ideas will lead you hand needle and into the brilliant, for a better future!
