NSK B-912 bearing

Bearing B-912

These are from NSK's LY25 product series of linear bearings and rail. KY20 bearings also have metal scraper as shown. These are very heavy-duty units with special coating on both rail and bearings to inhibit rust and corrosion.We wiped off this unit to photograph it, but you can still see some grease on the rail and around the bearing scraper.
