Omah bantalan cincin slewing minangka salah sawijining struktur bantalan beban sing paling kritis ing excavator. Iki nyambungake gerbong ndhuwur menyang undercarriage lan kudu nyerep beban radial, aksial, lan momen gabungan sing gedhe banget sing digawe nalika ngeduk, ngayun, lan lelungan - nalika njaga geometri sing tepat kanggo bantalan cincin sing mati lan bolong gear internal.
Ningbo Ruican mrodhuksi omah bantalan ring slewing nggunakake proses casting investasi silika sol ing 42CrMo4 (setara AISI 4140) baja paduan, ngiring dening mesin CNC rampung saka bolongan bantalan, pola bolt-bolongan, lan pasuryan soyo tambah pindah. Rute casting investasi ngirim omah sing cedhak-net-wangun karo bagean tembok seragam lan aliran gandum uninterrupted, Nyingkiri cacat internal lan kekirangan arah gadhah fabrications gandheng utawa casting wedhi atos.
Saben omah disedhiyakake ing kondisi sing diobati kanthi panas (quenched lan tempered nganti 269-302 HB) kanthi permukaan mesin sing dipriksa ing CMM nglawan gambar pelanggan. Apa sampeyan mbangun excavator kelas 20-ton, 30-ton, utawa 40-ton - utawa layanan aftermarket - kita gawé kanggo gambar lan volume.
| Parameter | Specification |
|---|---|
| Material | 42CrMo4 alloy steel (AISI 4140 / DIN 1.7225 equivalent) |
| Manufacturing Process | Silica sol investment casting + CNC machining |
| Heat Treatment | Quenched & tempered, 269–302 HB (adjustable to requirement) |
| Casting Tolerance | ISO 8062 CT5–CT6 (machined critical features per drawing) |
| Typical Weight Range | 80–350 kg per housing |
| Surface Finish | Ra 1.6–3.2 µm on machined faces; shot-blasted as-cast surfaces |
| Inspection | CMM dimensional check, UT/MT crack detection on request, EN 10204 3.1 material certificate |
| MOQ | Negotiable — prototype to serial production volumes |
| Applicable Machines | 20–40 ton excavators, material handlers, demolition machines |
A omah gandheng ngenalaken HAZ (zona kena pengaruh panas) kekirangan persis ing ngendi retak lemes miwiti. Casting wedhi ing kelas ukuran iki asring nggawa inklusi slag lan porositas sing mung katon sawise mesin kasar - scrapping bagean pungkasan ing produksi. Casting investasi karo cangkang sol silika ngasilake baja sing luwih resik kanthi isi gas sing luwih murah, lan densitometry lan kekerasan ing omah kita mriksa saben anomali sing nyekel panas sadurunge mesin diwiwiti.
