The newly developed molded polyamide cage presented by NTN-SNR reportedly features an improved and stronger material and an optimized cage pocket design with square cells. According to the French exhibitors, this offers a single contact point instead of a curved contact surface, which generates less friction and less temperature rise. The design also provides more spaces for lubricant to pass through, thereby improving lubrication. The better material and design is claimed to increase the speed of rotation by 50 percent up to a speed factor of 1.6 million NxDm.
