What material is used for the wheels in CamelConvey's enclosed track chain?

CamelConvey uses bearing steel for the wheels in our enclosed track chains.

The wheels in an enclosed track chain must provide high wear resistance and high hardness, as they continuously roll under load inside the track. Material selection is critical to ensure long-term reliability and safety.

Below is a comparison between bearing steel and carbon steel:

Bearing Steel:

✔ Achieves high and stable hardness after heat treatment

✔ Excellent wear resistance

✔ Specifically designed for rolling and load-bearing applications

✔ Better microstructure control after heat treatment

✔ Higher toughness at high hardness levels

✔ Much lower risk of brittle fracture under working loads

Carbon Steel:

✔ Can reach high hardness after heat treatment

✔ However, when hardened to a high level, it becomes more brittle

✔ Cracking may occur during the heat treatment process

✔ Even if no cracking appears initially, micro-cracks may develop

✔ Under load during operation, these cracks can expand and cause failure

✔ Wear resistance is generally lower compared to bearing steel

At CamelConvey, performance and reliability come first. To ensure the wheels maintain high hardness, strong wear resistance, and resistance to cracking under load, we always use bearing steel for our enclosed track chain wheels.

Although the material cost is higher, this decision guarantees longer service life, safer operation, and consistent product quality for our customers.
