6008-2RS (I.D.=40mm, O.D.=68mm, Thickness=15mm); 6008-2RS bearing are shielded on BOTH SIDES to keep lubricant in; Chromium Steel long-life bearings, smooth and low noise.
F686ZZ bearing is a flanged ball bearing made of chrome steel in which the bearing is metal shield from both sides It has an 6mm inner diameter, a 13mm outer diameter, a 5mm thickness, and an 15mm flange.
The radial and axial clearance can be adjusted during installation and use; The large cone angle mainly bears the axial and radial combined loads, which are mainly axial loads. Generally, it is not used alone to support pure axial loads. When configured in pairs (installed with the same name opposite).
F608ZZ bearing is a flanged ball bearing made of chrome steel in which the bearing is metal shield from both sides It has an 8mm inner diameter, a 22mm outer diameter, a 7mm thickness, and an 25mm flange.
