A bearing holder is to be formed by injecting a melted resin, from a plurality of resin injection gates provided at a peripheral edge portion of a substantially annular cavity formed in a molding die, into the cavity. At least one column portion is provided with a resin reservoir capable of reserving therein the melted resin. A cross-sectional area of a communication portion of the resin reservoir configured to communicate with the column portion is equal to or smaller than of a cross-sectional area of the resin injection gate.

Sensor devices for a rolling bearing and roller bearings including said sensors are disclosed. The sensor device may include at least one sensor configured to connect to one bearing race in a manner fixed against relative rotation. At least one signal transmitter may be configured to connect to the other of the bearing races in a manner fixed against relative rotation. The sensor device may further include an outer ring configured to be fastened on an end face of the outer race of the rolling bearing and an inner ring configured to be fastened on an end face of the inner race of the rolling bearing. The sensor and the signal transmitter may be arranged on mutually opposite lateral surfaces of the outer and inner rings.

A motor assembly includes a shaft, a bearing, at least one fluid channel, a temperature sensor, a lubricant supply pump, and a controller. The bearing defines a bearing interface against which the shaft rotates. The at least one fluid channel is fluidly coupled with the bearing interface. The temperature sensor detects a temperature of the bearing. The lubricant supply pump is fluidly coupled with the at least one fluid channel to transport lubricant from a lubricant supply to the bearing interface via the at least one fluid channel. The controller receives the bearing temperature from the temperature sensor, determines a difference between the bearing temperature and a supply temperature of the lubricant, determines a lubricant flow rate based on the difference, and transmits a control signal to the lubricant supply pump to cause the lubricant supply pump to transport the lubricant to the bearing interface at the lubricant flow rate.

A heterogeneous composite consisting of near-nano ceramic clusters dispersed within a ductile matrix. The composite is formed through the high temperature compaction of a starting powder consisting of a core of ceramic nanoparticles held together with metallic binder. This core is clad with a ductile metal such that when the final powder is consolidated, the ductile metal forms a tough, near-zero contiguity matrix. The material is consolidated using any means that will maintain its heterogeneous structure.

A method of forming a component includes heating the component to a burnishing temperature above 500 degrees Fahrenheit, and burnishing a surface of the component while the component is at the burnishing temperature to densify the surface. The burnishing process at an elevated temperature may be integrated into other processes, such as the sintering or heat treating processes.

The invention relates to a sliding bearing (1) comprising a support element (2) on which at least one additional functional layer (3) is arranged which consists of a silver-based alloy with silver as the main constituent of the alloy. The functional layer (3) contains, in addition to silver, at least one element from a group including gallium, manganese, nickel, copper, zinc, germanium, indium, tin, antimony and aluminum, wherein the total content of said elements is between 0.01 wt. % and 70 wt. % and the remainder is formed by silver containing production-related impurities, with the proviso that the proportion of each of the elements gallium, manganese, nickel, zinc, germanium and antimony in the binary silver-based alloys is a maximum of 49 wt. %, the proportion of indium being not more than 10 wt. %, the proportion of tin or copper content in the functional layer embodied as a sliding being not more than 10 wt. % and 14 wt. % respectively.

A machine arrangement comprising a crankshaft which is supported by at least one roller bearing including bearing rings and roller elements between the bearing rings, wherein the roller bearing is connected with a device for delivering of a lubricant to the area of rolling contact between the bearing rings and the roller elements. To improve the supply of lubricant to the roller bearing and to supply the right amount of lubricant in dependence of the temperature of the roller bearing, the device for delivering of the lubricant comprises a lubricant reservoir and a flow path from the lubricant reservoir to the area of rolling contact, wherein a valve element is arranged in the flow path for controlling at least one of a flow of lubricant and a pressure of lubricant in dependence of the temperature of at least one of the roller bearing and the valve element.

An agricultural vehicle includes a frame, a wheel supporting the frame, and a rockshaft coupled to the frame and operable to pivot with respect to the frame. The rockshaft has an outer surface, an inner surface and an open end. An internal end cap is positioned on the open end of the rockshaft. The internal end cap has an inner surface and an outer surface. The inner surface of the internal end cap contacts the outer surface of the rockshaft. An external end cap is positioned on the open end of the rockshaft and contacts the outer surface of the internal end cap. A fastener connects the external end cap to the frame to retain the external end cap on the rockshaft.
