White metal bearings

Babbitt metal or bearing metal , is any of several alloys used for the bearing surface in a plain bearing. He disclosed one of his alloy recipes but kept others as trade secrets. Other formulations were developed later.

The material is therefore also known as babbitt metal and the process of renewing it is called re-babbitting. Ever since its invention, white metal has been used extensively as a running layer on plain bearings. White metal bearings are made from white metal alloys, which can include tin, lea zinc, and bismuth.

Of course, each white metal bearing will contain a different combination of alloys, depending on the desired strength and other requirements. It should also be shock resistant and tough while being ductile enough to account for slight misalignment pri. White metal is primarily used to line cast iron, steel and bronze bearing shells. White metal can be either a tin based or lead based alloy containing moderate amounts of copper and antimony. Tin based white metals are used for high load and high operating temperature applications.

Welcome to Mangal Industry. Diagnosing plain bearing failures is all about recognising the tell-tale signs of different wear out and other failure modes. Careful inspection of the failed bearing will usually reveal vital visual clues that can lead to a potential cause for the failure.

Journal or plain bearings consist of a shaft or journal which rotates freely in a supporting metal sleeve or shell. There are no rolling elements in these bearings. Their design and construction may be relatively simple, but the theory and operation of these bearings can be complex.

Pin Ball Machine Part 5. This is achieved primarily by the lubricant, with a hydrodynamic oil film to keep the surfaces apart. The oil film can never completely prevent contact, particularly at times such as start up. We manufacture all types of White Metal -lined bearings , Including: All Michell type vertical and horizontal bearings. We bring decades of specialist engineering experience and knowledge to plain bearing issues. From diagnosis and report on faults, through repair, manufacture, replacement and upgrade solutions.

We offer a full spectrum of engineering Services, from assisting OEM bearing manufacturers with new designs, to supporting the end users in the field with existing equipment. Both new and revised bearings can, when require be tested by Lloyds, Veritas etc. Standard procedure at Hageman is the testing of the bonding of the white metal on the bearing by using modern ultrasound equipment. Under normal operating conditions they have a very long life, they allow large momentary overloads, are able to handle lubricant problems and if misalignment occurs they are able to conform and compensate.

The heavier and more powerful the engine, the stronger the bearings must be to provide.

With an extensive knowledge of the casting of white metals, Harfords have expertly traine experienced and competent staff who provide a white metal service to our clients. Heat generated within the oil film may cause the shaft temperature to rise more rapidly than the bearing housing. Differential expansion of the shaft can cause temporary reduction in the journal bearing clearance, which in severe cases may cause metal -to- metal contact in the zones of minimum clearance in profile bore bearings. Manufacturing of White Metal bearings to customer’s drawings has been the core of our business for over a hundred years. We offer a bearing design and reverse engineering service where we can supply all the bearing performance calculations.
