Animation demonstrating SKF solutions for hardening tunnels in the ice-cream industry During hygienic cleanings, temperatures can change quickly from sub-zero to 35°C, causing air to expand inside the bearings. This causes "breathing" problems and can result in water or moisture entering the bearings, often resulting in corrosion and grease emulsification. Poor performance of the degraded grease may cause metal to metal contact, raceway distress and high friction, impacting reliability and energy consumption. Re-lubrication to purge the bearings of moisture can lead to contamination of the product. In extreme cases, ring fractures can result from blocking caused by frozen water or lubricant. As a consequence, unplanned stoppages, excessive replacement parts with related labor costs may occur. Purging can result in extended use of expensive food grade grease. All this leads to an increase in overall maintenance costs and loss of productivity. SKF solid oil filled stainless steel deep grove ball bearings significantly reduce breathing in the bearing that can occur due to rapid temperature changes, limiting the corrosion effects resulting from hygienic cleanings. The result: • Extended bearing life • Reduced downtime and maintenance costs: spare parts, lubricant and labour. |
