Steel Bearing Housing
Custom Steel Castings & Machining — From Your Drawing to Finished Parts
This Steel Bearing Housing is a robust mounting component designed for heavy‑duty conveyor systems, industrial gearboxes, and rotating machinery. It is manufactured by our in‑house Lost‑Wax Casting (Investment Casting) + CNC precision machining process. The use of carbon steel or alloy steel (e.g., 45# steel, 40Cr, or stainless steel 304/316) provides an excellent balance of high load capacity, impact resistance, and fatigue life under demanding operating conditions. The lost‑wax casting process ensures tight dimensional tolerances, smooth surface finish, and the ability to form complex internal geometries — all critical for bearing housings requiring precise shaft alignment, reliable bolt‑on mounting, and long‑term durability in harsh environments.
Our one‑stop approach — covering mold design, lost‑wax casting, CNC machining, surface treatment (anti‑rust oil, primer painting, or zinc plating), and engineered packing — delivers a ready‑to‑install bearing housing that meets high‑strength mechanical requirements and withstands vibration, shock loads, dust, moisture, and extreme temperatures.

Our Advantages
Technical Advantages
1
Pattern shop, sand/investment casting lines, CNC machining, heat treatment,surface treatment, and inspection lab — all under one roof. No outsourcing. This vertical integration gives us complete control over lead time, quality, and traceability from raw melt to finished part.
2
Before pattern production begins, we deliver a detailed DFM report covering solidification analysis, riser placement, core design, and machining allowance optimization. We flag potential shrinkage risks, wall thickness issues, and internal cavity challenges early.
3
We specialize in components with intricate internal passageways, and high pressure-tightness requirements — such as valve bodies, pump housings, and exhaust manifolds. In-house X-ray, ultrasonic, and leak/pressure testing ensure internal integrity. Where applicable, controlled weld repair with full NDT verification and post-weld heat treatment keeps your parts on track without hidden outsourcing delays.

Service Advantages-总部接待区 1 拷贝
Material Advantages
1
We charge only carefully sorted steel scrap into our electric arc or induction furnaces. Every heat is chemically analyzed by spectrometer before tapping, with real-time adjustments to carbon, manganese, silicon, and alloying elements. Deoxidation and desulfurization practices ensure clean steel with low inclusion content.
2
Every production batch is identified by a unique heat number. Chemical composition reports, mechanical test records (yield strength, tensile strength, elongation, impact toughness at ambient or low temperature), and heat treatment charts are compiled into a traceable dossier — from furnace charge to finished casting.
3
We pour a comprehensive range of carbon steels, low-alloy steels, and stainless steels — including WCB, WCC, LCC, 4140, 8630, CF8 (304), CF8M (316), duplex stainless steels, and heat-resistant grades. Whether you need wear resistance, corrosion resistance, high-temperature strength, or low-temperature toughness, we match the alloy to your operating environment.
Service Advantages
A dedicated project manager oversees the entire process — from design review to final delivery — ensuring efficient communication at every stage.
Quotations are typically provided within 24–48 hours. Production progress is updated regularly through photos and production data, with continuous customer feedback collection throughout the project.
Full batch traceability and 24-hour response to quality-related issues ensure reliable post-delivery support.
