Field Support: YD Friction's 4500ORS series discs are engineered for the most demanding oilfield and mining gearbox overhauls.
Extreme Durability for Harsh Environments
Allison units in oilfields and mines are subject to 24/7 operation and extreme heat. Our YD Friction components ensure:
- Broad Oil Compatibility: Our friction binders are chemically inert to standard Allison TES-295 fluids, preventing surface glazing.
- Superior Power Density: Engineered to handle the massive pressure spikes found in oilfield fracturing pump applications.
- Parallelism Control: Flatness maintained within 0.05mm to prevent parasitic drag and overheating during disengagement.
Disclaimer: All manufacturer's names, OEM part numbers (e.g., Allison 29537365), and descriptions are used for identification purposes only. YD Friction products are high-quality aftermarket parts and are not products of the original manufacturer.
