  • Lubricant FAQs
    Most ball or roller bearings (except needle bearings and some thrust bearings) as large as 25" outside diameter or as small as 1/8" inside diameter can be lubricated with Cobra Solid Lubricant. However, the bearing and its cage should be metal with at least C3 internal clearance. Note
  • About Cobra Solid Lubricant (CSL)
    CSL (Cobra Solid Lubricants) is graphite based solid lubricant specifically designed for ball and roller bearings. It is a mixture of graphite and binders that is prepared in such a way as to allow the mixture to be injected into the clean bearing and then thermally cured to harden the mixture
  • Bearing Closures - Bearing Seals and Bearing Shields
    Ball and roller bearings are available with different types of shields and seals. These are commonly referred to as closures. Closures can extend bearing life by preventing contaminants from reaching the critical surfaces inside the bearing, and they help retain the lubricant in the bearing
  • Dimpled bearings run smoother, longer
    A golf-ball-like surface improves lubricant flow inside bearings. SKF Engineering & Research Centre A pitted surface can hold minute reservoirs of lubricant. Rolling action transports oil or grease to critical contact points inside the bearing. Any golfer knows that a ball with dimples has vastly
  • Slick bearings slash friction
    , the bearings generate less heat and run cooler, extending lubricant life. One example of the bearing's potential: If every wind-turbine gearbox bearing worldwide was replaced with Energy Efficient tapered roller bearings, the turbines would generate an estimated extra 770 million kW-hr per year
  • New spin on spindle bearings
    types install at a spindle work end because they handle both axial and radial loads. The other end houses a cylindrical roller bearing which, by design, floats or slips axially to compensate for spindle thermal expansion yet operates with zero radial clearance for rigidity. Within these two bearing
