The present disclosure is directed to a spring bearing which is used in a roller system for a developer cartridge. The spring bearing has a front surface and a rear surface and an angled relief cut extending from the front surface to the rear surface.

There is provided a resin composition for a machinable liner of a sliding member. An ultraviolet curable resin composition for a self-lubricating liner contains a (meth)acrylate compound having an isocyanuric acid ring represented by the following formula and PTFE as a solid lubricant. In the formula (1), X is a group which contains an acryloyl group and is composed only of C, H, and O. Y and Z are groups each composed only of C, H, and O. PTFE is contained in an amount of 10 to 50% by weight with respect to a total amount of the ultraviolet curable resin composition. The ultraviolet curable resin composition is suitable for a self-lubricating liner 24 of a spherical bearing 20 having an outer race 22 and an inner race 26.

The invention relates to a method for producing a rolling bearing cage for a rolling bearing comprising at least one row of rolling elements. In the method according to the invention, a ring or a ring element made of a metallic solid material is provided and shaped by a forming process and/or a cutting, material-removing process into an annular or segmented main body of the rolling bearing cage. The main body has openings for receiving a respective rolling element, the main body being heated to a temperature above a minimum coating temperature for thermal coating with a thermoplastic material powder, wherein the main body is then immersed in a fluidized bed containing the thermoplastic material powder, wherein thermoplastic material powder adheres to the main body, melts and forms a contiguous coating while the main body is present in the fluidized bed, and wherein, after the coating, the main body is removed from the fluidized bed. The invention further relates to an axial-radial rolling bearing with the described rolling bearing cage.

A shaft voltage reduction structure is mounted on an electric machine having a bearing house and a rotor shaft rotatably connected together, and includes an electrically conductive main body, at least one electrically conductive bearing, and an electrically conductive shaft. The conductive main body is mounted to a bottom of the bearing house and includes a conductive shaft barrel projected from a center thereof. The conductive shaft barrel internally defines a shaft receiving hole, in which the conductive bearing is received. The conductive shaft includes a connecting end and a pivotal end connected to the rotor shaft and the shaft receiving hole, respectively. A shaft voltage across the rotor shaft of the electric machine is guided by the conductive shaft to release in a closed loop formed among the conductive main body, the conductive bearing and the bearing house, so as to reduce the shaft voltage of the electric machine.
