ZF 0635.330.050 BALL BEARING for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 0635.330.050 BALL BEARING is a precision-engineered OEM genuine component designed to maintain smooth rotational support within the planetary gear sets of ZF WG100, WG130, and WG131 transmissions. This bearing reduces friction between rotating shafts and stationary housings, ensuring consistent power delivery under heavy load. The SKU 0635.330.050 is a direct replacement part that fits into the intermediate shaft or output shaft assembly, where it absorbs radial forces and maintains gear alignment. When installed alongside the 4143101022 HOUSING, this bearing forms a critical load-bearing interface that prevents metal-on-metal contact during high-torque operation.

Symptoms of Failure

• Whining or grinding noise during gear engagement — A worn 0635.330.050 bearing produces a distinct metallic whine that intensifies under acceleration, often mistaken for gear wear.
• Vibration through the shift lever or chassis — Excessive radial play in the bearing causes shaft wobble, transmitting vibration into the transmission housing and driver cabin.
• Intermittent gear slipping under load — As the bearing loses its spherical integrity, gear mesh depth fluctuates, leading to momentary power loss during uphill or loaded driving.
• Metallic debris in transmission fluid — Spalling of the bearing race releases fine steel particles that contaminate the oil, accelerating wear on the 0636302014 SCREW PLUG sealing surfaces.

Technical Specifications

Compatibility

This ball bearing is engineered specifically for ZF WG-series transmissions, including the WG100, WG130, and WG131 models. It also fits select WG180 and WG200 variants where the intermediate shaft bearing bore matches the 35x72x17 mm dimensions. Always verify clearance against the 4143301044 HOUSING bore before installation. The bearing works in conjunction with the 0631329135 SPRING PIN to lock the outer race in position, preventing rotation within the housing pocket.
