ZF 0735.371.723 TAPER ROLLER BEARING for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 0735.371.723 TAPER ROLLER BEARING is a critical component engineered to manage axial and radial loads within the planetary gear sets of ZF WG100, WG130, and WG131 transmissions. This OEM genuine part (SKU: 0735.371.723) sits directly between the rotating shafts and the stationary HOUSING, ensuring precise gear alignment and smooth torque transfer. By reducing friction at high rotational speeds, this bearing prevents premature wear on adjacent components and maintains the structural integrity of the gear train. The tapered roller design allows it to handle the combined thrust and radial forces common in heavy-duty industrial gearboxes.

Symptoms of Failure

• Whining or grinding noise during gear engagement: A worn 0735.371.723 bearing produces a distinct metallic whine that intensifies under load, often mistaken for gear chatter. This noise signals that the roller elements have lost their surface integrity.
• Excessive shaft end-play or vibration: When the taper roller bearing fails, the shaft it supports develops noticeable axial movement. Operators may feel vibration through the transmission housing, particularly during deceleration or when shifting between forward and reverse.
• Metal debris in transmission oil: Flaking or spalling of the bearing races releases fine metallic particles into the lubricant. If you observe glitter-like contamination during an oil change, the 0735.371.723 bearing is likely the source.
• Overheating near the bearing journal: A seized or binding taper roller bearing generates localized heat, which can discolor the surrounding COVER and degrade nearby seals.

Technical Specifications

Compatibility

This taper roller bearing is specifically designed for the ZF WG series of powershift transmissions. It is a direct replacement for units in the WG100, WG130, and WG131 models. The bearing also fits select variants of the WG180 and WG200 series when used in the input shaft position. Always verify the existing bearing part number before ordering. The 0735.371.723 is secured in place using a CYLINDRICAL PIN and fastened with a CAP SCREW to prevent axial migration during operation.
