1 15/16'' Cast Iron Pillow Block UCP210-31 Peer Type

A cast iron pillow block bearing is a type of bearing that is commonly used in industrial and agricultural applications. The bearing is housed within a cast iron casing that provides both stability and protection for the rotating component within. Pillow block bearings are designed to support a shaft and keep it properly aligned, allowing it to rotate freely. They are commonly used in conveyor systems, pumps, fans, and other rotating machinery. Cast iron pillow block bearings are durable and resistant to corrosion and wear, making them well suited for harsh operating environments.

If our purchasing items are non-standard type of bearings, is there any minimum order quantity requirements from your factory?

Yes, if it’s special type of bearings, as we need to open the new mold, if your order quantity is too small, then the prices are quite expensive and because some items might need the special bar or forging material, if small quantity, we could not get the material from outsides, besides, for the cage or steel ball and seals, we need some mimimum order quantity also, so there is MOQ request for the special bearings, at present, we could not tell you what’s the MOQ quantity we need, as it depends on your projects and how’s the bearing look like? But for the standard type, no order is too big or too small for us, we could try the best to help customers.
