precision cross-crossed roller bearing ru124uucc0p5 xru8022xuucc0p5 inner diameter 80mm outer diameter 160mm height 22mm robot knuckle arm b

the internal structure of the cross roller bearing adopts the roller in 90° vertical cross arrangement with each other. the roller is equipped with an interval retainer or isolation block to prevent the mutual grinding between the roller tilting rollers. large axial and radial loads are carried because the rollers are aligned vertically to each other via spacer retainers on a 90° v grooved rolling surface. nylon separator, low moment of inertia, low starting torque, easy to control angle division.syi
