The Hinge pin is usually stainless and sits on one large ball bearing. These hinges take a lot of lateral weight (sides of pin on wall). They wear rapidly when not greased and the cylindrical pin hole becomes oval shaped and the gate starts to sag.
Failure Rate Estimates for Mechanical Components
Example: A ball bearing has a Weibull shape parameter of 1.3 and characteristic life of 50,000 hours. What is the average failure rate for the bearing? If the bearing is scheduled for preventive maintenance replacement every 10 years, the hazard rate varies from a lower value of zero at "time zero" to an upper bound of 31 failures per million hours (FPMH) for bearings …
