Ball bearings are one of the most important inventions in the world. There are few people who know about their history or how they work. Ball bearings play a critical role in many machines and devices that we use today. Here is a brief history of ball bearings and why they are so important.
The first known use of ball bearings was in ancient China. They were used to support axles in carts and chariots. The bearings allowed the wheels to rotate more smoothly and with less friction. This made transportation much easier and more efficient. The modern ball bearing was invented by Philip Vaughan, a Welsh inventor, in 1794. His design was based on earlier Bearings used in clocks. Vaughan’s ball bearings were made from hardened steel and were used to support the axles of carriages. These bearings were much smoother and more durable than the earlier Chinese ones.
Ball bearings are now used in a wide variety of applications. They are used in cars, bicycles, roller skates, skateboards, and many other machines. Ball bearings help to reduce friction and wear on moving parts. This makes them last longer and reduces the need for maintenance. Ball bearings are also used in medical devices such as X-ray machines and MRI scanners. The history of ball bearings is a long and interesting one. They have played a vital role in the development of transportation and industry, but the benefits are clear to see!
Contact & Non-Contact
It’s easier to keep out contaminants that could cause bearing failure with the sealing shield. Sealed bearings generally have a longer service life than open bearings because they are more resistant to contamination and require less maintenance.There are two types of sealed ball bearings: contact seals and non-contact seals. Contact seals are made of rubber or metal and make contact with the inner race, keeping lubricant in and contaminants out. Non-contact seals, also known as labyrinth seals, have a series of grooves and bumps that form a barrier between the bearing and the outside world, trapping lubricant inside the bearing while keeping contaminants out. Both types of sealed bearings provide excellent protection against contamination but have different advantages and disadvantages.
Contact seals are more effective at keeping out contaminants but can trap heat inside the bearing, leading to higher temperatures and shorter service life. Non-contact seals allow heat to escape but are not as effective at keeping out contaminants.
Sealed ball bearings are the best choice for applications where contamination is a concern. The extra protection they provide can extend bearing life and improve performance. That said, there are many bearing suppliers UK, so it’s crucial to choose the best one. Check out their reviews, see when their business began and the quality and breadth of their products. If their products are used in many industries, including automotive, aerospace, and medical, then you’ll know you’ve found a trusted supplier.
