Sealed ball bearing tend to differ from open and shielded ball bearings since they do not provide room for re-lubrication, which occurs in the case of leakage. Bearing and seals which do not provide room for re-lubrication tend to have a shorter lifespan when compared to shielded bearings which are properly maintained, when used appropriately they can over a variety of benefits when compared to other kinds of ball bearings. Below are some of the benefits of bearings and seals, with particular focus on industry.

Require little or no maintenance

Unsealed ball bearings can only be properly maintained through regular lubrication. The lubrication is very crucial in ensuring there is no failure. In contrast, sealed bearings do not demand regular lubrication. The lubrication is done during the manufacturing stages and one should never think of lubricating them once again. There are many bearing suppliers in the UK, but not all of them will stock sealed ball bearings, so it’s important to understand the importance here, especially in terms of quality. In spite of where bearings are being applied this feature will minimise the labour but they are more helpful which the bearing is positioned in the parts, which are not easily accessible. The unsealed bearings are positioned at the hard so as to reach sections, which will demand you to disassemble the surrounding elements in order to do the necessary repairs.

No contaminants

Contaminants enhance the possibilities of wear and tear additionally minimizing the durability of the machine components. Unsealed bearings comprise of routes which provide room for the addition of lubricant and also the entry of contaminants.

Sealed bearings have seals which are usually intact thereby preventing the entrance of contaminants. The seal is also meant to ensure lubricant remains inside and ensures there is no entry for contaminants. The failure of the seal directly affects the running of the bearing which may result in its failure.

No chances of over-lubrication

Sealed bearing ensures there are no accidental over-lubrication which can be witnessed. Unsealed bearings are prone to failures as a result of over lubrication in relation to under-lubrication.

To get the most out of sealed bearings avoid installation of grease fitting. Ensuring your machine is kept properly will ensure the technicians operating the machine will not have to lubricate the sealed bearings.

Contact and non-contact

The contact seals bearings are in contact with the inner track which is the central point for spinning of the ball bearings. This is essential in preventing the entry of moisture but also accelerates the rate of wear and tear as well as resulting in higher levels of operating temperature. The above are the benefits of bearings and seals, but we know you may have lots more questions, so please do not hesitate to dro us any questions, and we can cover this exciting subject in more detail with a follow up blog post, as there’s so much to say!
