40Cr
For DRS112~DRS200, we use 40Cr hot-rolled round steel, subjected to rigorous quenching
and tempering processes.
DRS250~DRS500 employs 40Cr forgings with comprehensive tempering treatment.
This material offers high tensile strength, completed with both overall quenching and
surface quenching treatments, achieving a hardness of HB300-380. Each walking wheel has a
guiding function. When utilizing wheel flange guidance, the minimum
The intricately designed gap between the inner surface of the wheel flange and the edge of the track can be as precise as 1mm, showcasing engineering precision.
The track can be as small as 1mm. The same exacting gap can also be achieved by strategically arranging guide wheels, ensuring smooth operation.
Achieve this precision by arranging guide wheels. If wear is anticipated, expertly harden the walking wheel tread or guide wheel rim.
To counteract any potential increase in wear, the walking wheel tread or guide wheel rim can be expertly hardened.
Experience the durability of a hardened wheel, meticulously engineered to HRC56 ± 2 (HB530) standards, completely eliminating slippage.
Our hardening technique for the walking wheel is meticulously designed to significantly reduce wear, prolonging the lifespan of your equipment.
polyurethane
Polyurethane, a marvel of modern synthetic rubber material, offers superior resistance characteristics, surpassing other synthetic rubbers in performance.
Its resistance characteristics far exceed those of traditional synthetic rubbers, positioning it as an innovative choice for advanced applications.
Polyurethane walking wheels deliver a significantly elevated friction coefficient compared to metal materials, greatly enhancing their suitability for demanding applications.
Boasting a high coefficient of friction, they are ideal for applications that demand a high dynamic response and superior performance.
The exceptional shock absorption characteristics of polyurethane walking wheels minimize operational noise, enhancing user experience.
Its extraordinary shock absorption properties ensure that walking noise is kept to a minimum, creating a more serene operational environment.
While polyurethane walking wheels excel in many areas, please note that their load-bearing capacity, compared to metal wheels, is reduced.
The load-bearing capacity of polyurethane walking wheels is notably diminished when compared with their metal counterparts.
With lower ground contact pressure, polyurethane walking wheels are ideally suited for smooth, concrete surfaces.
Particularly adept for concrete surfaces, these wheels deliver smooth and efficient movement due to their low ground contact pressure.
Thanks to the high friction coefficient, polyurethane walking wheels glide seamlessly over concrete surfaces; they are also perfect for friction-driven applications.
The impressive friction between the wheel tread and contact material ensures optimal performance.
These wheels are particularly effective for friction-driven applications, with acceleration capabilities reaching an impressive 1.5m/s2.
Polyurethane walking wheels support dynamic applications with acceleration potential up to 1.5m/s2, ideal for high-performance needs.
Polyurethane materials are engineered to withstand temperatures of up to 100 degrees Celsius without compromising on performance and durability.
These materials remain robust and reliable at temperatures soaring up to 100 degrees Celsius, ensuring consistent performance.
Hardening of wheels
For wheels experiencing severe wear, as evidenced by abundant iron filings on the track edge, our wheel hardening solutions are the answer.
Intense wear, such as the presence of iron filings on the track edge, signals the need for hardening the tread and rim of metal running wheels.
Our meticulous hardening process for the tread and rim extends to a depth of 2-3mm, ensuring durability and resilience.
The hardening extends to a depth of 2-3mm, ensuring that the DRS112~DRS200 running wheels remain free from rim damage markings.
Achieving a hardness value of HRC56 ± 2 (HB530), these wheels exhibit exceptional resistance to damage.
The hardness value reaches HRC56 ± 2 (HB530), providing unmatched durability and wear resistance.4
