A gaming system includes a housing having gaming components therein. The housing has a door opening and a door capable of rotating about a hinge axis defined by a set of hinge pins rigidly affixed to the housing. Attached to the door are a set of hinge arms having a set of specially shaped hinge slots positioned around the hinge pins. The hinge arms are additionally coupled to the housing by a set of spring components. When the housing door is not in a closed position, the spring components bias the door to an open position. When the housing door is in the closed position, the spring components bias the door in a direction defined by the hinge slots such that the door remains in a neutral position minimizing a spacing gap along one edge of the door. A set of roller guides align the door with a set of corresponding roller pins when the door approaches the closed position, and a locking mechanism is configured to latch the door to the housing in the closed position.

A method, implemented by an electronic gaming machine (EGM), includes providing an electronic display mounted to the cabinet of the EGM and disposed in a normal operational position to portray a wagering game to a user, the display in the normal operational position having an orientation of one of landscape or portrait. The display is moved from the normal operational position to a maintenance position in order to permit access for a technician to components in a space in the cabinet behind the display when the latter is in the normal operational position, the display in the maintenance position having an orientation of the other of landscape or portrait, the display in the maintenance position displaying information to the technician.

A mechanical end face seal of the non-contacting type includes a primary seal ring having a back section, a seal face section and a middle section between the seal face and the back sections, each primary ring section having a radial dimension, defined as the difference between the outermost radius and the innermost radius of said respective section, the radial dimension of the back section being in a ratio relative to said middle section of between about 1.8 to about 2.8, and more preferably of between about 1.9 to about 2.5, and most preferably about 2.0 to about 2.3. Additionally, the mating seal ring includes grooves extending from one seal ring circumference toward the other and terminating adjacent a dam at a radius R.sub.g, it is beneficial to have the boundary between the grooves and the dam have a radius R.sub.g slightly larger or smaller, within about 10%, than the outer radius of the middle section.
