SKF bearings with Solid Oil Relubrication-free solutions for wet environments The Power of Knowledge Engineering

Reduce downtime and maintenance costs in wet and contaminated environments Applications Food and beverage, pharmaceutical Marine Material handling Product information

Reduce downtime and maintenance co and contaminated environments Bearings operating in wet and contaminated environments can suffer from unreliability and very short service life, resulting in costly maintenance and downtime This is particularly true for applications exposed to the elements and those that must undergo frequent washdowns Attempts to extend service life in these conditions by frequent relubrication tend to be relatively unsuccessful and there is a risk of contamination of the product by the ejected used grease († fig. 1) Fig. 1 The challenge: wet conditions The presence of high...

About Solid Oil Solid Oil is an oil saturated, polymer material that virtually fills all of the free space in the bearing († fig. 3) The polymer material is moulded into the bearing forming very narrow gaps around the rolling elements and raceways, enabling the bearing to rotate freely The polymer material has a porous structure, with millions of micro-pores, that hold the lubricating oil retained by surface tension In service, oil is released from the material into the narrow gaps between it and the bearing components, thus providing effective minimum quantity lubrication Consistent lubricant...

Features and benefits of bearings with Solid Oil Longer lubricant life • Large amount of oil available • Eliminates lubricant churning • High quality, synthetic oil resists oxidation Resists washout • Solid Oil cannot be washed out of the bearing • Water cannot mix with the oil or Solid Oil polymer Virtually eliminates lubricant leakage • Solid Oil retains oil in the bearing • Integral bearing seals increase the oil retention even further Protects against the ingress of contaminants • Close osculation between Solid Oil and the rollers and raceways significantly reduces the ingress of contaminants...

Applications Food and beverage, pharmaceutical In the food, beverage and pharmaceutical processing industries, extremely clean and sanitary conditions are a basic requirement To maintain these conditions, machinery frequently undergoes high pressure washdowns with aggressive detergents Any risk that the product might be contaminated, for example from grease or oil leakage, must be minimised and all materials used must be considered acceptable for incidental contact with the product and detectable if contamination should occur Bottle filling station In conventional bottle filling stations, bottles...

Marine In the marine industry, deck machinery is impacted by harsh environments and continual salt water spray Maintaining deck machinery offshore can be dangerous and time consuming, making it important that critical components such as bearings be weather resistant and designed for reliable operation Because the operational and financial consequences of downtime are severe, bearing related failures are not an option Deck machinery Customer issue A customer using standard spherical roller bearings with grease lubrication and external seals in the rope sheaves of a heave compensation system experienced...

Material handling Cranes used in material handling operations must withstand severe mechanical and physical demands Bearings must meet heavy lifting requirements and be weather resistant and reliable Crane failure can result in serious financial and operational consequences, and, in some cases, can be life threatening Port cranes In port and deck cranes, salt water spray can impact bearings in critical components including wheels, drums and rope sheaves Water ingress into these components can result in lubrication failure, wear and corrosion To reduce the related risk of premature bearing failure,...
