\nGenuine OEM-spec swing motor assembly<\/span><\/strong>\u00a0\u2013 OEM part number 452-6209 (juga dirujuk sebagai PCR-4B-20A). Direkayasa sesuai spesifikasi peralatan asli Caterpillar untuk CAT 305.5E2, 306E2, dan ekskavator mini kelas 5\u20136 ton yang kompatibel<\/span>. Ini adalah unit baru dengan spesifikasi pabrik \u2013 bukan hasil remanufaktur, bukan pengganti generik.<\/span><\/p>\n<\/li>\n\nKualitas Produk \u2013 Hongtengda Parts<\/span><\/strong>\u00a0\u2013 The swing motor is the heart of the upper structure rotation system, responsible for driving the rotational movement of the cab, boom, arm, and bucket<\/span>. It converts hydraulic power into controlled rotational motion, enabling the excavator to swing horizontally for efficient digging and material placement<\/span>. When this motor fails, the machine cannot position itself for productive work.<\/span><\/p>\n<\/li>\n\nDirect replacement for CAT 305.5E2 and 306E2<\/span><\/strong>\u00a0\u2013 Specifically designed for Caterpillar 305.5E2, 306E2, and compatible models including 305E, 305E2 CR, 305.5D, and 306<\/span>. Mounting flange, shaft interface, and hydraulic port configurations match the original Caterpillar specifications exactly \u2013 no modifications, no adapters<\/span>.<\/span><\/p>\n<\/li>\n\nPCR-4B-20A platform \u2013 NACHI\u2019s proven mini excavator swing technology<\/span><\/strong>\u00a0\u2013 The PCR-4B-20A is part of NACHI\u2019s renowned PCR series of axial piston swing motors<\/span>. PCR series motors integrate an axial piston hydraulic motor with a planetary gearbox and braking mechanism in a compact assembly, providing smooth, reliable rotation for 5\u20136 ton class machines<\/span>.<\/span><\/p>\n<\/li>\n\nHigh torque output for 5\u20136 ton class work<\/span><\/strong>\u00a0\u2013 Delivers the torque and rotational power needed for precise slewing operations even under full bucket loads. The swing motor works in tandem with the swing drive gearbox to rotate the upper structure smoothly<\/span>. The assembly weighs approximately\u00a0<\/span>60 kg (132 lb)<\/span><\/strong>\u00a0with dimensions of\u00a0<\/span>45 \u00d7 35 \u00d7 35 cm<\/span><\/strong>.<\/span><\/p>\n<\/li>\n\nIntegrated parking brake for slope safety<\/span><\/strong>\u00a0\u2013 The swing motor features a built\u2011in spring-applied, hydraulically-released disc parking brake<\/span>. When the hydraulic control console is raised or the engine is stopped, the brake engages automatically, holding the upper structure securely on slopes<\/span>. When a swing operation is started, the brake releases instantly for immediate response<\/span>.<\/span><\/p>\n<\/li>\n\nRelief and makeup valves for circuit protection<\/span><\/strong>\u00a0\u2013 Integrated relief valves protect the swing motor against pressure spikes during sudden stops or overloads<\/span>. Makeup (anti\u2011cavitation) valves prevent vacuum damage during rapid deceleration<\/span>. Together, these valves ensure smooth, jerk\u2011free slewing and extend motor life.<\/span><\/p>\n<\/li>\n\nKonstruksi kokoh untuk kondisi yang menuntut.<\/span><\/strong>\u00a0\u2013 Key components are crafted from high-quality materials with specialized treatments for excellent wear and corrosion resistance<\/span>. The rational structural design simplifies maintenance and extends service life<\/span>. Operates reliably in harsh conditions including dust, moisture, and temperature extremes<\/span>.<\/span><\/p>\n<\/li>\n\nVerifikasi visual pra-pengiriman<\/span><\/strong>\u00a0\u2013 Sebelum pengemasan, kami akan mengirimkan kepada Anda foto-foto terperinci beresolusi tinggi dari unit aslinya (flensa pemasangan, alur gigi, ulir port, bagian cor, serta kondisi keseluruhan). Anda harus menyetujui pengiriman tersebut \u2013 kami tidak pernah mengirimkan barang tanpa persetujuan Anda terlebih dahulu.<\/span><\/p>\n<\/li>\n\nPengiriman cepat<\/span><\/strong>\u00a0\u2013 Waktu tunggu 5\u20138 hari kerja dari gudang Guangzhou kami. Kapasitas pasokan bulanan 300 unit, tersedia untuk pesanan satuan atau grosir.<\/span><\/p>\n<\/li>\n<\/ul>\n2.
