A suspension strut bearing for a motor vehicle includes a cap, a guide ring rotatably mounted relative to the cap about an axis of rotation, and a bearing arranged between the cap and the guide ring. The cap has a profile with a rib structure open in a radial direction on a front face directed towards a body of the motor vehicle. In some example embodiments, the profile of the open rib structure is formed from multiple webs. At least one first web may be formed at least partially in a circumferential direction on the cap, and at least one second web may be formed at least partially in the radial direction on the cap.

A connecting rod includes a hollow body with a ring at each end and a centre, a thickness wall e, the wall defining an outer perimeter pe and an inner perimeter pi, a surface section s being contained between the outer and inner perimeters, wherein the outer perimeter pe increases from the ends of the hollow body to the centre of the connecting rod, the hollow body maintaining a constant surface section s, the thickness e decreasing from the end to the centre of the connecting rod.

Methods for making a tribological bearing wear surface for a compressor component are provided. Such methods involve semi-solid metal casting, where an admixture of solid lubricant particles and a metal alloy material is heated to melt the metal alloy material, while the lubricant particles remain in a solid phase. The alloy material and solid lubricant have substantially different densities. The metal alloy material may be a copper, iron, or aluminum alloy, for example. The method further comprises mixing and cooling the admixture to form a semi-solid slurry admixture. Next, the method comprises introducing the semi-solid slurry admixture into a die. Finally, the semi-solid slurry admixture in the die is solidified to form a solid component having the solid lubricant particles homogenously distributed within a metal alloy material matrix, thus forming a metal matrix composite. Compressor components made from such methods are also provided.

An object is to provide a motion guide apparatus that can facilitate an assembly operation. An end member (4a, 4b) including an inner peripheral side of a direction changing path (2c) is placed on an end surface in a movement direction of a moving member body (3). At least one of a pair of the end members (4a and 4b) includes an opening (21) linking to the inner peripheral side of the direction changing path (2c) to load rolling elements (42) into a circulation path. Opposing surfaces (18) of the pair of the end members (4a and 4b) to the moving member body (3) are formed in flat surfaces. The pair of the end members (4a and 4b) molded integrally with a holding portion (5) is incorporated into the moving member body (3) in a direction orthogonal to the movement direction of the moving member body (3). A lid member (7a, 7b) closes the opening (21) in the end member (4a, 4b).

The present invention provides a method for manufacturing an air bearing with discreet orifices designed to facilitate a non-contact interface between surfaces. The process involves using a mold wherein wires or filaments are placed to form air channels within a cast. Various materials, such as silicone, steel, and composites, can be used for the mold. After casting and curing the material, the wires are removed, leaving precisely defined channels that allow air to flow through, creating a cushion of air that maintains a gap between the bearing and the surface it operates on. This gap can be adjusted by changing the air pressure or the number of channels. The bearing components may be further machined or secured in a housing connected to an air source, enabling the bearing to hover and operate efficiently in various applications. The invention allows for multiple configurations of the air channels to optimize airflow distribution as required.

A bearing unit for a marble cutting machine has a radially outer ring, rotatable with respect to an axis of rotation (X) and is provided with a radially outer flange portion. Additionally, the bearing unit is provided with a stationary radially inner ring with a through hole in which the ratio between a dimension of an internal diameter (D) of the through hole and a dimension of the axial thickness (T) of the radially inner ring is between about 6.7 and about 11.1. A row of rolling bodies is interposed between the radially outer ring and the radially inner ring. A sealing shield is made of composite material and interposed between the radially inner ring and the radially outer ring, rotatable with respect to the rotation axis (X) and steadily anchored to the radially outer ring. The shield is provided with a sensor molded in it.
