One of the most useful and popular bearing materials is babbitt metal. Babbitt metal is soft and can bond to various materials like steel, bronze, and cast iron. Additionally, it can withstand heavy loads while also staying corrosion resistant. As it is such a useful product, your company may benefit by using babbitt metal for your next manufacturing project.

When speaking about babbitt metal, it is most commonly available in two types: lead or tin-based. Each of these products has benefits and is available as ingot or wire. The wire can be used for metalizing applications or flame spraying.

Tin-Based Babbitt

Tin-based babbitt is primarily made of tin but can also contain copper, antimony, and lead. If you are using machinery that will transport food, the tin babbitt should always be lead-free. While babbitts are considered soft in most cases, the tin strengthens it, making it useful in load-carrying situations.

A common trait that makes tin-based babbitts attractive to manufacturers is its low friction resistance and low wear. As it can flow well even in high-pressure situations, it is useful if there is machinery that is not properly lubricated along the shafts and bearings. Of course, one needs to keep up with upkeep and babbitt bearing repair to reap the benefits. Tin-Based Applications

As tin has high thermal connectivity, this tin-based babbitting will transport heat away from your equipment. This trait means that there will be fewer issues with equipment overheating or breaking down. These are most commonly used for farm machinery, conveyors, elevator applications, and general machinery.

Lead-Based Babbitting

In addition to lead, these will also include a bit of tin and antimony. As lead-based babbitt has high corrosion resistance, it is ideal for high levels of humidity or heat. This type of babbitting in Canada is also useful because of its high thermal conductivity, conformity, and embeddable qualities.

Lead-Based Applications

Most commonly, lead-based babbitting is used for low to medium-speed machinery. For bearings, it is excellent for moderate cyclic loads and unidirectional loads. Like tin-based babbitt, it is used in general machinery, line shafting, conveyors, and elevator applications. As it is corrosion-resistant, it can be used aboard sea-vessels or underwater.

If you are unsure of which type of babbitt to utilize, you can speak to Canada Metal experts. We can also help you with babbitt bearing repair. Finding babbitting in Canada is easier if you have a trusted company by your side that has the experience necessary to lead you in the right direction.
