The main purpose of the retainer is to allow the rolling elements to maintain the distance between the inner ring and the outer ring and to maintain normal and stable activities, especially during the continuous high-speed operation process, to prevent irregularities between the rolling elements. Interference causes abnormal sound to occur, which affects the service life. Generally, low-carbon steel plates are the main choice of materials, and brass or stainless steel or synthetic resin nylon is also used in special environments or different conditions of use. And we also specially designed a cage-free full ball bearing for the frame linkage mechanism, and filled the space saved by the cage with steel balls and redesigned the configuration. In the reciprocating motion mode, this high-strength structural design It has increased its rigidity and increased load, and its life span has been extended. After years of feedback, it has been favored by many customers and the market.
