Overview
The ZF 0750.118.380 ROLLER BEARING is a critical load-bearing component engineered for the planetary gear sets within ZF WG-series transmissions, specifically the WG258, WG261, and WG308 models. This OEM genuine part ensures precise rotational support for the sun gear and planet carriers, reducing friction and maintaining proper gear alignment under high-torque conditions. The SKU 0750.118.380 is a direct replacement for the original bearing, designed to withstand extreme axial and radial loads encountered in heavy-duty industrial applications. When installed alongside the 4646101156: TRANSMISSION HOUSING, this roller bearing helps maintain the structural integrity of the entire gear train assembly.
Symptoms of Failure
When the 0750.118.380 roller bearing begins to wear, operators may notice several distinct failure indicators. Abnormal gear whining or grinding noises during acceleration or deceleration often signal bearing degradation, as the rollers lose their smooth raceway contact. Vibration in the transmission housing is another common symptom, particularly at specific RPM ranges, indicating uneven roller wear or pitting. Metal debris in the transmission oil filter or pan is a clear sign of bearing spalling, which can rapidly damage adjacent components like the 4646301327: HOUSING. Finally, intermittent gear slippage or delayed engagement may occur as the bearing fails to maintain proper gear spacing, leading to misalignment of the planetary set.

Compatibility
This OEM roller bearing is specifically designed for the following ZF transmission series: WG 258 Series, WG 260 Series, WG 261 Series, WG 308 Series, and WG 311 Series. It is also compatible with earlier WG180 and WG200 variants where the planetary gear set uses a 75x118x38mm bearing profile. For proper installation, always pair this bearing with new 0636015304: HEXAGON SCREW fasteners and 0636101828: CAP SCREW hardware to ensure correct clamping force on the bearing carrier. The bearing fits both standard and heavy-duty planetary carriers within these transmission models.
