Finally, think about the performance tradeoffs. In some cases, off-the-shelf bearings can be adapted to meet specific requirements through modifications, such as relubrication or material coatings. For example, thin dense chromed (TCD) plating can be applied to improve wear resistance, reduce friction and improve corrosion resistance — ideal for harsh environment like food processing or marine. This approach can achieve the desired performance improvements in a cost-effective manner, bridging the gap between standard and custom solutions. In cases where off-the-shelf bearings almost meet the requirements, additional customisation — like applying specialised lubricants — can improve performance without the need for fully-customised designs. For example, perfluoropolyether (PFPE) lubricants are commonly used in aerospace and vacuum applications because of its excellent thermal stability and resistance to extreme temperatures. Polyurea-based greases offer excellent oxidation stability and are ideal for high-speed electric motor bearings, while food grade lubricants ensure compliance with safety regulations in food and pharmaceutical processing. This approach offers a middle ground, balancing cost efficiency with tailored performance. By thoroughly evaluating these factors, engineers can make informed decisions that balance functionality, cost and efficiency. The decision between custom and off-the-shelf bearings ultimately comes down to striking the right balance between functionality, cost and efficiency - three factors that directly influence overall machinery performance, durability and long-term value. By understanding the demands of the application and exploring ways to enhance standard bearings through relubrication or coatings, engineers can often achieve high-performance outcomes without the cost and lead time of a fully custom solution. *Chris Johnson is managing director of bearing specialist SMB Bearings For further information please visit: http://www.smbbearings.com/ Claim your FREE monthly digital subscription For the latest news and techology visit our website NEWS | FEATURES | PRODUCTS | CASE STUDIES April/May 2025| Issue 486 www.pwemag.co.uk @PWEmagazine1 The importance of energy efficiency for industrial ESG goals Inside this issue: 10 > Smart Manufacturing Week/ Maintec Preview 14 > Bridging the gap between CMMS & emerging technologies 28 > The rise of the electric thermal fluid heater page 30 @plant-&-works-engineering PWE Plant & Works Engineering Since 1981 www.pwemag.co.uk
