A bearing housing (212; 256) may comprise a cylindrical body and a groove (228; 268) formed in an inner surface of the cylindrical body. The groove (228; 268) may be configured to interface with a bearing (210; 254). A tapered surface (226; 262) may be formed on an outer diameter of the cylindrical body. A wear plate (216; 258) may be disposed over the tapered surface (226; 262). An elastic material (214; 260) may be between the tapered surface (226; 262) and the wear plate (216; 258). The tapered surface (226; 262) may be conical. A length of the tapered surface (226; 262) may be less than half the length of the bearing housing (212; 256). The tapered surface (226; 262) may be tapered at an angle based on a deflection angle of a piston (202; 252). A second tapered surface (262) may be formed on the outer diameter of the cylindrical body. An elastic material (214; 260) may be between the second tapered surface (262) and the wear plate (216; 258). |
