A bearing cage segment for a segmented bearing cage includes a plurality of walls that define a pocket configured to receive a rolling element and an insert element captively retained in an opening in a first one of the plurality of walls. The insert element may be configured to guide a rolling element retained in the bearing cage and/or be configured as a lubricant reservoir.

A metal foam ball, several millimeters in diameter, is manufactured to have an open-pore structure to absorb fluid (e.g., gas and liquid) such as water or lubricant. As an example, a copper foam ball is manufactured via a freeze casting method using prepared oxide powder slurry where a spherical silica gel mold is used to freeze the slurry, which is subsequently dried at low temperature in vacuum and then sintered at high temperature. For improved oxidation, copper alloy foam ball or copper foam ball coated with tin can also be manufactured through the same method. For improved strength, steel, copper-nickel alloy, or titanium foam ball can also be manufactured through the same method.

A low friction coated article includes a first structure that has a first lubricated surface coated with a first polyelectrolyte coating. A second structure has a second lubricated surface with a second polyelectrolyte coating opposite the first lubricated surface. The first and second polyelectrolyte coatings include alternating layers of positively charged polyelectrolyte layers and negatively charged polyelectrolyte layers hydrated with a lubricant.

A rolling bearing makes use of a porous rolling element and a selected kind of lubricant to impregnate with; is usable in various conditions; does not discharge foreign objects; and features low dust generation and long life. The rolling bearing includes an outer ring 2; an inner ring 1; and a plurality of rolling elements 3 assembled between mutually opposed outer ring track surface 2a and inner ring track surface 1a. The plurality of rolling elements 3 is provided by a combination of a porous rolling element 3a impregnated with a lubricant and a non-porous rolling element 3b.

The invention relates to a kit including a plurality of modules which can be integrated in a bearing installation space. The modules include a plurality of supply management modules for supplying bearing components, a plurality of functional modules for measuring bearing state variables and/or for triggering and/or activating specified events under specified conditions, and a plurality of infrastructure modules for implementing communication tasks and/or for saving and processing specified and/or recorded data. The invention further relates to a bearing arrangement having a bearing and a plurality of modules which can be connected to a common connection medium, wherein the modules are components of the kit according to the invention.

A bearing assembly comprising a rolling element bearing having a first row of rolling elements arranged in a first bearing cavity between a first inner raceway and a first outer raceway of the bearing, and having a second row of rolling elements arranged in a second bearing cavity between a second inner raceway and a second outer raceway of the bearing. The assembly further comprises an annular grease cartridge arranged between the first and second rows of rolling elements. The annular grease cartridge is at least partly formed from a honeycomb structure having axially extending passageways filled with a grease lubricant, wherein at least some of passageways are open towards the first and second bearing cavities.

A deep groove ball bearing includes an outer ring, an inner ring, a cage, and steel balls. The cage is provided between the outer ring and the inner ring. Pockets are formed in the cage, and the steel balls are placed in the pockets. The cage is split into an upper cage body and a lower cage body. Pocket grooves are formed alternately in each of the upper cage body and the lower cage body. A connecting portion is provided between adjacent pocket grooves in the upper cage body. A positioning portion is provided between adjacent pocket grooves in the lower cage body. An insertion piece and an insertion groove are provided between the connecting portion and the positioning portion. The insertion piece and the insertion groove are configured to be fixed with each other to form a fixed connection between the upper cage body and the lower cage body.

A method is provided that forms a solid film on a bearing component of a rolling bearing. A solution containing a fluorine compound and a lubricant having no functional group is allowed to adhere to the bearing component as a first liquid film (adhesion step). The adhering first liquid film is hardened to form the solid film on the bearing component. The rolling bearing including the bearing component with the solid film formed thereon is rotated. The rolling bearing is washed in a washer fluid containing the same lubricant as that used in the adhesion step, and the washer fluid is allowed to adhere to the bearing component as a second liquid film. Then, the adhering second liquid film is dried.

Disclosed is a bearing race comprising a surface having a plurality of pores formed therein. A lubricant is provided in the pores. The race has a body having a porous volume contiguous with the surface. The surface includes a load bearing zone configured to be in contact with a rolling element of a bearing, the pores being distributed on the surface to provide the lubricant to the load bearing zone.

A linear guideway includes a rail, a sliding block with two foot members, a circulating member with two receiving chambers, two sets of balls and two lubricating plates. The receiving chambers of the circulating member receive the foot members of the sliding block respectively, so that the rail, each foot member of the sliding block and the circulating member form a circulation channel for one respective set of balls to run. The two lubricating plates are adjacent to the two circulation channels and contact the two sets of balls to provide lubrication to the balls. In this way, the linear guideway conceals two lubricating plates in the sliding block, which can maintain the length of the sliding block without affecting the stroke, and ensure that the running path does not produce a step difference, so that the smooth running of the ball can be kept consistent.
