Abstract
An antifriction bearing of the roller type for a pulling system of weaving loom including two end plates secured to the inner race and positioned respectively and axially close to each flank of the rollers, end plates lying radially beyond the raceways and the end plates and the inner race being intended to be mounted between two lateral flanges. At least one end plate has a shape defining at least one cavity adjoining all or part of a flank of the rollers and able to accept a lubricant. The inner race has two lateral shoulders each one defining an axial bearing surface for each flange, and a width of the inner race with its lateral shoulders is substantially equal to a distance separating the outermost axial faces of the end plates.

An antifriction bearing of the roller type for a pulling system of a weaving loom, comprising:
- an inner race and an outer race lying on opposite sides of a plurality of rollers in a radial direction and defining inner and outer cylindrical raceways, respectively,
- two end plates secured to the inner race and positioned respectively and axially close to each flank of the plurality of rollers, each end plate extending radially beyond the inner and outer raceways, the end plates and the inner race being adapted to be mounted between two lateral flanges of the pulling system, at least one end plate having a shape defining an annular cavity adjoining the plurality of rollers over an entire radial extent of adjacent flanks of the plurality of rollers and being configured to accept a lubricant, the inner race having two lateral shoulders each one defining an axial bearing surface for each of the flanges, respectively, a width of the inner race with the lateral shoulders being equal to a distance separating outermost axial faces of the end plates, and wherein the lubricant consists of a solid-state packing positioned within the annular cavity and between the rollers.
A pulling system for a weaving loom comprising, at least one link rod and at least one lever, wherein the link rod and the lever are connected by means of an antifriction bearing, the antifriction bearing including an inner race and an outer race lying on opposite sides of a plurality of rollers in a radial direction and defining inner and outer cylindrical raceways, respectively, two end plates secured to the inner race and positioned respectively and axially close to opposite flanks of the plurality of rollers, each end plate extending radially beyond the inner and outer races, the end plates and the inner race being adapted to be mounted between two lateral flanges of the pulling system, at least one end plate having a shape defining an annular cavity adjoining the entire radial extent of an adjacent flank of the plurality of rollers and in which a solid state packing lubricant is retained, the inner race having two lateral shoulders each one defining an axial bearing surface for each of the flanges, respectively, and a width of the inner race with the lateral shoulders is equal to a distance separating outermost axial faces of the end plates, and the flanges consisting of the link rod and being secured to the inner race by means of a bolt clamped at the flanges.
