Overview
The ZF 0735.302.558 BALL BEARING is a precision-engineered OEM genuine component designed to support rotating shafts within the BP210, BP230, WG190, and WG210 transmission series. This bearing reduces friction between the shaft and the transmission housing, ensuring smooth power transfer and maintaining proper gear alignment. The SKU 0735.302.558 is a critical element in the gear train assembly, often positioned near the input or output shaft to handle radial and axial loads. When installed alongside the 4657101088: TRANSMISSION HOUSING, it provides stable support for the entire rotating assembly, preventing metal-on-metal contact that can lead to premature wear.
Symptoms of Failure
When the ZF 0735.302.558 ball bearing deteriorates, operators may notice a distinct grinding or rumbling noise during gear shifts, particularly under load. Another common symptom is excessive shaft play or vibration in the transmission, which can cause misalignment and accelerate wear on adjacent components. You might also observe metal particles in the transmission fluid during routine checks, indicating that the bearing raceways are spalling. In advanced cases, gear slipping or delayed engagement occurs as the bearing loses its ability to maintain proper shaft positioning, leading to inefficient power transfer.

Compatibility
This OEM ball bearing is engineered for use in several ZF transmission families. It is a direct fit for the BP 210 Series and BP 230 Series, commonly found in medium-duty commercial vehicles. Additionally, it is compatible with the WG 190 Series and WG 210 Series, which are used in heavy-duty off-road and construction equipment. While the bearing may also suit the WG180 and WG200 models, always verify the shaft diameter and housing bore before installation. For proper assembly, this part works in conjunction with the 4657201183: HOUS.FRONT SECT and the 4657201184: HOUSING REAR PART to ensure correct bearing seating and alignment.

Frequently Asked Questions
Q: How do I know if the 0735.302.558 bearing needs replacement?
A: Listen for abnormal grinding noises during operation or check for excessive radial play in the shaft. If you detect metal particles in the oil, replace the bearing immediately to avoid damage to the 4657298111: HOUSING REAR SECTION.
Q: Can this bearing be used in a WG180 transmission?
A: While the 0735.302.558 is primarily designed for BP210/BP230 and WG190/WG210 series, it may fit WG180 models if the shaft diameter matches. Always cross-reference the inner diameter of 35 mm with your existing bearing before ordering.
Q: What other parts should I replace at the same time?
A: It is recommended to replace the 4681301015: FIXING PLATE and both 4681301016 and 4681301017 screen sheets to ensure optimal cleanliness and bearing retention.
