Specifying Concentricity and Perpendicularity in Tungsten Carbide Bushing Drawings

Tungsten carbide bushings are known for their excellent durability and wear resistance. However, their performance largely depends on how well they are aligned within the housing, which is determined by two key factors: concentricity and perpendicularity. This article explores the importance of specifying these two factors in tungsten carbide bushing drawings and how they affect […]

Thermal Expansion Mismatch: Housing Design for Tungsten Carbide Bushings

Tungsten carbide bushings are known for their wear resistance, but thermal expansion mismatch with the housing can affect their performance. Tungsten carbide has a low coefficient of thermal expansion (CTE), while materials like steel or aluminum expand more with temperature changes. This mismatch can lead to issues such as excessive wear or mechanical failure. This […]

Recommended Surface Roughness for Tungsten Carbide Bushing Bores

Tungsten carbide bushings are known for their durability and wear resistance, making them essential for high-performance applications. One key factor that affects their performance is the surface roughness of the bushing bores. Proper surface roughness ensures reduced friction, better lubrication, and longer service life. This article will discuss the importance of surface roughness for tungsten […]

Clearance Fit Charts for Tungsten Carbide Bushings and Pump Shafts

In mechanical systems, tungsten carbide bushings and pump shafts work together to ensure smooth, efficient performance. One critical factor in their compatibility is the clearance fit, which refers to the space or gap between the bushing and shaft. A proper clearance fit ensures that there is neither excessive friction nor too much movement, both of […]

Density, Toughness, and Impact Resistance: What Sets WC Bushings Apart?

Tungsten carbide (WC) bushings are known for their exceptional hardness and wear resistance, making them ideal for heavy-duty applications. However, what truly sets WC bushings apart is their density, toughness, and impact resistance. These three key properties make WC bushings suitable for demanding environments where wear, shock, and pressure are constant challenges. This article explores […]
