ZA – 1 2 Bearing Design Notes
Zincaloy bearings offer good resistance to atmospheric corrosion as well as a variety of plant environments. However, direct exposure to corrosive liquids and gases should be avoided. Contact liquids should have a pH of 6-11.5 to avoid corrosion problems. Zincaloy may experience bimetallic galvanic corrosion if in contact with other metals, however, under atmospheric conditions this is generally small and of no concern.
It can be of concern in a constantly wet environment or in sea water. Under these circumstances the material should be tested to determine its suitability
Most bearings perform best if lubricated, including Zincaloy bearings. However, under extreme conditions of dry running, ZincaloyTM is superior to bronze under such conditions because a thin film of Zincaloy is smeared over the shaft which protect it from wear and damage/
Zinc alloy metals generally do not spark when struck by rusted ferrous materials
