HERCULES JD / NH UNITIZED PISTON SEAL

    JD / NH Unitized Pistons

    The John Deere and New Holland Unitized Pistons are designed to handle a broad range of application parameters. The piston body is machined to exact dimensions and is constructed using four components: a high strength steel body, a non-metallic bearing, a rubber loading ring, and a filled PTFE seal ring. The non-metallic bearing is molded to the piston using a special proprietary process.
