What is the difference between Zinc Alloy Bearing Units and Cast Iron Bearing Units?

1.The mainly material of Zinc Alloy Housing is ZA27,ZA303, so Zinc Alloy Bearing Units have low density and high thermal conductivity, low friction coefficient, good wear resistance and corrosion resistance.they aresuitable for medium and low-speed heavy-duty applications.

2.the material of Cast Iron Housing is HT200.The strength and hardness of Cast Iron Bearing Units are high, and their wear resistance is good.Under high pressure and impact loads, cast iron housings have good toughness and are not easily broken. However, cast iron is prone to rusting, and has a relatively short service life, and is also prone to deformation in high-temperature environments.

1. In light load situations

Under light load conditions, zinc alloy material bearing housing often become the mainstream choice. This is because under such load pressure, zinc alloy materials are durable enough and the manufacturing cost is relatively low.

2. Medium load scenarios

Under medium load conditions, both cast iron and zinc alloy housings can be used. This is because under such load pressure, they can all meet the demand, but we need to make specific choices according to the special requirements of the usage environment.

3. Heavy load scenarios

Cast Iron Bearing Units are more suitable for heavy load applications. This is because cast iron materials have superior strength and toughness, which can maintain stability under heavy pressure and heavy loads, while having a longer service life.

In short, different materials have their own advantages and disadvantages in different application scenarios,if you do not know how to choose the different material for the housings, contact us now wendy@winstarbearing.com, we have professional engineers to guide you.
