Grease fittings are rarely found on today's consumer go, appliances, or cars, because maintenance-free products have more sales appeal to the general public. They are still commonly used on industrial, agricultural, and mining equipment where shaft diameters exceed 20 millimeters, as well as electric motors larger than 5 kilowatts. One of the reasons for this is that commercial users have plans and enforcement for lubricating schedules, so the expense of sealed bearings may be unnecessary. For example, in ship or power plant MRO, the management will ensure and document that an employee does the lubrication rounds as needed, whereas inpidual consumers often ignore maintenance needs. In commercial use, as long as the lubrication rounds are being added to the workload of an already-needed employee, thus not expanding the payroll, this is the less expensive route.
