Durable Tungsten Carbide Bearing Sleeves for Oilfield Equipment

Carbide bushings for oilfield equipment.
Processing difficulty:
The inner and outer diameters have high precision, the upper and lower cross grooves need to be symmetrical, and the inner hole end face needs to be mirror polished.

Size: Φ76xΦ47x139.5mm

Application:

Sanxin specializes in the custom design and manufacturing of wear sleeve products and bearing sleeves for severe service applications in high volumes.

High precision bearing sleeves are used in a variety of applications. Bearing sleeves or adapter sleeves serve as the mounting surface for bearings. When used in combination with spacer sleeves it allows other the components on the shaft to be positioned properly.
This arrangement also makes it easier for disassembling the bearing for applications where frequent mounting and dismounting is required.
A bearing wear sleeve is a high precision component that functions as a primary running surface. It protects shafts and spindles by preventing scoring and scratching. It can also compensate for shaft irregularities.
Durable bearing wear sleeves can significantly prolong the service life of shafts and minimize ongoing maintenance and repair requirements.
Sanxin bearing sleeve products are custom manufactured for your specific applications in tungsten steel, cemented carbide, and various graded of wolfram carbide.

Sanxin Carbide Products Features:

The processing technology for tungsten carbide products varies depending on the type and intended use of the product. Here is a general processing workflow for tungsten carbide products:

1. Raw Material Preparation: Select high-purity tungsten powder and carbon powder as raw materials.
2. Material Mixing: Blend tungsten and carbon powders in specific proportions to ensure a uniform mixture.
3. Pressing and Shaping: Place the mixture into molds and subject it to high pressure to achieve the desired shape.
4. Initial Sintering: Place the pressed blank in a high-temperature furnace for initial sintering, forming a preliminary structure.
5. Powder Metallurgy Sintering: Subject the preliminarily sintered blank to powder metallurgy sintering, allowing carbon to react fully with tungsten to produce tungsten carbide.
6. Heat Treatment: Conduct heat treatment on the sintered product to adjust its crystal structure and properties, enhancing hardness and wear resistance.
7. Mechanical Processing: Employ machining processes such as cutting, milling, and grinding on the heat-treated blank to achieve the final product shape.
8. Surface Treatment: Optionally perform surface treatments, such as coating or polishing, to enhance surface properties as needed.
9. Quality Inspection: Conduct quality checks on the finished tungsten carbide products to ensure they meet specified technical standards and customer requirements.
10. Packaging and Delivery: After passing quality inspection, package the products and deliver them to customers.

It's important to note that different types of tungsten carbide products may have variations in this basic process, and specific processing techniques can also be influenced by product design requirements and intended applications.
