High-Performance DeVilbiss 525DS Motor Bearing (GS28-12)

Restore smooth, quiet motor rotation with this replacement DeVilbiss 525DS motor bearing. Specifically engineered for the internal GSE ZW280 compressor assembly, this precision bearing directly replaces worn motor bearings in DeVilbiss 525DS 5-liter stationary concentrators.

Symptoms of a Worn Compressor Bearing:

Grinding or Squealing: High-pitched friction noise coming from the internal compressor housing.
Elevated Motor Heat: Increased friction causing the compressor thermal overload switch to trip.
Increased Vibration: Excessive cabinet rattle caused by radial play in the motor shaft.
Low Pressure Alarms: Sluggish motor RPM leading to dropped sieve bed pressure.

Precision Sealed Construction

This replacement DeVilbiss 525DS motor bearing features hardened steel races and precision-ground ball assemblies. It is pre-lubricated with high-temperature synthetic grease rated for continuous 24/7 duty cycles. Consequently, it resists thermal breakdown under demanding continuous patient use. Additionally, dual rubber seals keep airborne particulate and compressor dust out of the internal raceways.

Specifications & Fitment:

Part Number: GS28-12

Compatible Concentrator: DeVilbiss 525DS (5-Liter Series)
