1) Including fastening screws or extraction threads.
2) Tightening torque for screws acc. DIN 912, strength class 10.9.
3) Attention! For fixing holes in the adjacent construction, observe the pitch of the bearing bores.
4) The screw counterbores of the large L-ring open toward the bearing bore; the bearing inside diameter is not supported in this area.
5) Please enquire at sales@eb-system.com in case of high speed applications.
6) Friction torques as a reference value: measuring speed nconst = 5 min-1; with myonic standard grease and standard amount of grease; without support ring; the bearing friction torque can increase up to 2.5 times at the limiting speed.
7) Measured on an installed bearing with ideal adjacent construction.
