LubeCoach: Machine Lubrication Calculation Calculate Optimize Grease Lubrication Practices at Your Fingertips LubeCoach is an innovative and easy to use device that can help with machine lubrication calculation by assigning the correct volume and frequency to grease lubricated element bearings 80% of grease lubricated bearings fail to achieve minimum life-cycle levels due to issues with

Bearings most often found in gearboxes are plain and roller bearings although plain bearings are seldom used in machine tools The most common types are ball and cylindrical roller bearings Some bearings are lubricated by air (e g dentist's drill) or water others by a general or specific gear oil or grease Plain bearings depend on a hydrodynamic lubricating oil film to reduce friction
