SKF Solid Oil bearing technology makes bearing relubrication unnecessary
SKF Solid Oil bearing technology provides a lubrication solution for bearings to withstand cold operating temperature extremes and rapid temperature changes typically encountered in a range of applications. The technology can be applied to virtually every bearing type (including stainless steel) with sufficient internal free space.
SKF Solid Oil consists of a polymer matrix saturated with lubricating oil that fills the internal space in a bearing and encapsulates the bearing’s cage and rolling elements. This minimizes the “breathing” phenomenon in a bearing (when air expands and contracts internally due to rapid temperature changes) and protects against entry of water or moisture during hygienic cleanings that can cause corrosion or grease emulsification in conventionally lubricated bearings. Since the polymer matrix contains two- to four-times more lubricating oil than standard grease-filled bearings, relubrication becomes unnecessary.
Food-safe SKF Solid Oil bearings are engineered to perform reliably in extreme temperature applications from -5º F to -49º F / -15º C to -45º C, withstand high centrifugal forces, and will not leak or otherwise contaminate the environment during production. Among available lubricants, NSF H1 approved or compliant selections are available down to -49º F / -45º C. Customized Solid Oil solutions can also be developed for high-temperature applications.
