Pressed Steel or Cast Iron?
These 4 bolt round cast iron housing units have an equivalent made of pressed steel. So which is the right one for your application? Which you decide to use will depend on what you intend to use it for. Cast iron is stronger, and is suitable for more demanding applications. However the housings themselves are heavier. Cast iron is a better choice where higher rpm speeds and heavier loads are involved.
Pressed steel is lighter, but not as strong in use. However because of their lightness, pressed steel housings are very easy to install. Use pressed steel for light to medium loads and for lower rpm speeds.
