PURPOSE:To obtain a hydrautic part excellent in compressive properties, oil resistance, heat resistance, fatigue resistance, and wearing resistance by forming it from a polyamide resin composition comprising poly(tetramethylene adipamide) and carbon fibers in a given proportion. CONSTITUTION:This hydraulic part is made of a polyamide resin composition which comprises 90-60wt.% poly(tetramethylene adipamide) and 10-40wt.% carbon fibers preferably obtained from polyacrylonitrile filaments and preferably having a fiber diameter of 0.1-30mum and a fiber length of 0.1-20mm, and which optionally contains 1-15wt.% high-density PE and/or fluorocarbon polymer. |
