Shielded bearingvs sealedbearing

Sealed and Shielded Bearings are available with one or two Rubber Seals or Metal Shields. This accommodates applications where a housed Bearing needs access to lubrication from one side while preventing moisture and contamination from entering at the other side.

Metal Shielded Bearings are often used in applications with risk of contamination where speed is still a priority, as they have no contact with the inner ring, ensuring low friction levels. Therefore, Metal Shielded Bearings are often used instead of Rubber Seals due to their speed capabilities. However, compared to Rubber Seals, they are not as good at protecting against moisture and fine dust, so this is something to consider when deciding whether Metal Shielded Bearings are the best option for your application.

Doubleshielded bearing

Bearings with Non-Contact Seals are similar to Metal Shielded Bearings as they can operate at the same speeds. However, these Bearings benefit from an improved sealing efficiency compared to Metal Shields.

There are many factors to consider when choosing whether a Rubber Sealed or Metal Shielded Bearing is the most suitable for your application. Compared to Open Type Bearings, Sealed and Shielded Bearings provide better protection against contamination and retaining lubrication. However, to maximize the service life of a Bearing and the performance of your machinery, the operational conditions need to be considered, as Rubber Seals and Metal Shields have different performance capabilities.

Rubber Sealed Bearings are considered maintenance-free as they are ‘sealed for life’ and do not require re-lubrication. Rubber Seals prevent loss of lubrication, and the Bearings are pre-packed with the correct amount of lubricant. Equally, Rubber Seals prevent moisture from entering the Bearings to avoid rust and ensure the lubrication does not wash away. When choosing a bearing, speed is an important factor to consider. Speed can be impacted in bearings with Rubber Seals due to the friction created where they have contact with the inner and the outer race.

According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
