A specialist manufacturing company approached SMB Bearings with a lubrication problem. They were using single and double row shielded and sealed bearings in pumps that were part of air purification systems for submarines. Unfortunately, the presence of acetone around the equipment meant that the test pumps were only lasting a couple of weeks.
When the bearings were removed from the pumps for analysis, there was no grease left in them.
The company asked the bearing manufacturer about a change of lubricant but the quantities were not large so only the standard grease was possible. They then approached SMB Bearings for help.
“We suggested that the company supply the standard bearings to us for cleaning and relubrication with one of the many solvent resistant greases we keep in stock. Two weeks later, we had cleaned and relubricated the bearings with the specialist grease and returned them to the customer. Some of the bearings had non-removable shields but with our unique system for relubricating bearings without removing the shields, this did not present a problem.”
The small quantities and the specialist nature of the problem is what SMB Bearings deal with every week on behalf of customers all over the world. The end result with this particular customer is that, months later, the bearings are still running normally.
