Determine the proper bushing length from the thickness of the center member to be inserted between the friction facings. 由设于摩擦板间的中心构件厚度，决定正确的轴衬长度。
Grease from a standard grease fitting is distributed to the shaft through a groove in the outside diameter of the bearing and from radial holes in the bushing's well. 从标准润滑油嘴注入的润滑油通过轴承外径的环形槽分流到阀轴上，并且从径向孔流入轴衬壁上。
