Bearings, Gears, Couplings, Pistons and Other Machine Components; Description and Lubrication Requirements.

---

• Plain and Rolling Element Bearings

• When I grease a bearing, how much grease should I add?
• How often do I need to regrease electric motor bearings?
• Using the shaft diameter, rpm and operating temperature of a bearing, how can you determine the proper viscosity for the lubricating oil?

• Gears: Spur, Herring Bone, Helical, Worm, Hypoid and Differential Types Reviewed

• What is the expected life of a gear set?
• What causes most abnormal gear wear?
• A plant has a small fleet along with many plant gearboxes calling for and industrial EP gear oil (SAE 90 Viscosity). Can an industrial EP gear oil be used in the differentials of the vehicles?

• Couplings: Flexure and Sliding Type (Gear, Block, Spring and Chain)

• Should I use a special grease for couplings or just a general purpose plant grease?
• What special considerations should be made when selecting a grease to lubricate a coupling?

• Pistons, Chains and Wire Rope

• Should all chains and wire ropes be re-lubricated?
• What things need to be taken into consideration when selecting a lubricant for a chain?
