Movigear

Bearing noise in a gearbox is usually fatigue from exceeded service life or contamination through a failed seal. Drain and inspect the oil for bearing material. If debris is present, the Movigear needs replacement.

Hard shifting in a manual-shift speed reducer is most often worn synchronizers or a bent shift fork. Drain the oil and inspect the fork and synchro rings before ordering parts.

Visible tooth wear means the unit is past its designed surface fatigue life or has been running under poor lubrication or overload. Assess wear depth, identify the root cause, and plan replacement. Adding oil will not reverse surface damage.

Gearbox vibration is usually shaft misalignment between the Movigear output and the driven machine, or worn bearings inside the unit. Check alignment first since it is the more correctable cause.

Grinding noise with metal particles in the oil means gear tooth spalling. Drain and inspect the oil immediately. If metal debris confirms gear damage, the unit needs replacement, not oil top-up.

Shaft seal leaks are the most common oil leak path on the Movigear. Confirm which seal is leaking, drain the oil, and replace the seal. Check that the shaft surface is not scored before fitting the new seal.

Radial shaft play in a SEW Movigear output means the output bearing is worn. Measure play with a dial indicator. More than 0.1 mm radial movement on the output shaft means bearing replacement, which requires a unit exchange or authorized workshop repair.

Gearbox overheating is most often low oil level or wrong oil viscosity for the ambient temperature. Check the oil level first, confirm the viscosity grade matches the SEW Movigear nameplate, and verify the duty cycle is within rating.
