Basically, JMC track rollers can be lubricated through both end of the stud with a suitable grease fitting.
The thread size of CFA10 and CFA10-1 series are M10x1.0.
Limiting speed increases 30% in oil lubrication and in case of sealed types, the limiting speed drops about 40% from the tabular data.
After assembly and oil lubrication, a hexagonal resin plug should be necessarily stopped up.
These types of '*' are produced on customer's request.
