Wuhan Honghao Machinery Co., Ltd

Wuhan Honghao Machinery Co., Ltd is based in China and currently lists 13 active products. The catalogue covers five top categories: bearings, steel balls, hydraulic equipment, railway fittings and flanges. Within the bearing segment the company offers tapered roller, deep‑groove ball, needle roller, spherical roller, self‑aligning ball, thrust ball, slewing and CV joint bearings. These items fall under HS chapter 84.82, which classifies ball and roller bearings and related parts. Steel ball products are recorded under HS 84.91 and stainless steel balls under HS 73.26, reflecting standard customs classifications for precision steel spheres. The hydraulic cylinders and linear guides are listed without HS codes in the supplied data but are typical ancillary components in machinery supply.

Specific entries include a Tapered Roller Bearing (HS 8482.20) made from Chrome Steel GCr15 / SAE 52100, and a Deep Groove Ball Bearing (HS 8482.10) using GCr15 / AISI 52100 material. Roller & Needle Roller products (HS 8482.40) are supplied in Chrome Steel GCr15 / SUJ2 with precision‑ground rollers, while the Needle Roller Bearing shares the same HS code and material. Spherical Roller Bearing (HS 8482.30) and Self‑Aligning Ball Bearing (HS 8482.10) also use GCr15/SUJ2 steel, with the latter offering cages of steel or engineering plastic. The catalogue lists a Chrome Steel Ball (HS 8482.91) composed of AISI 52100 with approximately 1 % carbon and 1.5 % chromium, and a Stainless Steel Ball (HS 7326.90) of 304/316 grade. Additional offerings such as the CV Joint (HS 8708.99) and the Slewing Bearing (HS 8482.60) use alloy steel 42CrMo hardened and tempered for high load capacity. Altogether the product set reflects a focus on precision‑engineered components for mechanical and transportation applications.

The supplier’s catalogue concentrates on rolling‑element bearings and precision steel balls, covering a spectrum from tapered roller to self‑aligning designs. In the bearing industry, common performance grades are defined by ISO 281 life rating and ABEC tolerance classes, with GCr15 / 52100 steel delivering hardness around 60 HRC and fatigue strength suitable for automotive and heavy‑duty machinery. Needle and roller bearings often conform to ISO 492 for dimensions and to DIN 620 for load ratings, while slewing bearings are typically specified by ISO 16630 for dynamic load capacity. Steel balls are graded by diameter tolerance (IT grades) and surface finish, with chrome steel balls frequently meeting ISO 3290 for spherical precision. The stainless steel balls align with ASTM A240 for 304/316 grades, offering corrosion resistance for food‑grade or medical equipment. Hydraulic cylinders, although not coded, are generally built to ISO 4424 standards for pressure ratings and piston‑rod surface finish.

Railway fittings and flange components, while not detailed in the product list, are typically manufactured to EN 1092‑1 flange pressure classes and UIC 710 for rail applications, ensuring compatibility with international rail infrastructure. Buyers often request material certificates confirming compliance with these standards alongside dimensional drawings.
