To avoid stress concentration NATR12 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 NATRD15 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, and must be constantly re-lubrication NATRD15 needle bearing |.
