Overview
The ZF 0750.119.160 ROLLER is a precision-engineered cylindrical component designed to function as a critical load-bearing element within the planetary gear sets of heavy-duty ZF transmissions. This OEM genuine part, identified by SKU 0750.119.160, is specifically positioned between the sun gear and the planet carrier, where it facilitates smooth rotational motion while managing extreme radial and axial stresses. As a hardened steel roller, it reduces friction between rotating elements, ensuring efficient torque transfer in construction machinery applications. The 0750.119.160 roller is manufactured to exacting tolerances to maintain gear alignment and prevent premature wear in high-torque environments.
Symptoms of Failure
When the ZF 0750.119.160 roller degrades, operators may notice distinct performance issues. Intermittent gear slipping under load is a primary indicator, often accompanied by a grinding noise during acceleration. Another common symptom is erratic transmission engagement, where the machine hesitates or jerks when shifting between forward and reverse. Metallic debris in the transmission fluid is a definitive sign of roller surface spalling, which can contaminate the entire hydraulic system. Finally, localized overheating near the planetary gear housing may occur due to increased friction from a worn or flattened roller surface.

Compatibility
This roller is engineered for integration into specific ZF transmission families commonly deployed in construction machinery. It is a direct fit for the ZF WG180 series, where it supports the planetary gear assembly in the forward clutch pack. The part also serves the ZF WG200 transmission, particularly in models with a 6-speed configuration. Additionally, the 0750.119.160 roller is compatible with the ZF 4WG-200 and ZF 5WG-200 variants, where it functions in the output planetary set. For ZF Ecomat 4HP590 and 6HP590 transmissions used in wheel loaders, this roller replaces worn components in the secondary gear train. Always verify your transmission serial number against the OEM parts catalog before installation.
