Abstract: The disclosure relates to a modular shuttering block defining a through-housing that connects a first face of the modular block and a second face opposite the first face, for the reception of a filling material; the modular block being provided with means for assembling with at least one other block. According to the disclosure, the modular block is in the form of a right prism with isosceles triangular bases formed by the first and second faces. The disclosure also relates to an assembly formed by a plurality of such modular blocks and finds application notably for the production of swimming pool steps.

Abstract: Rolling bearing (1) comprising an inner ring (3), an outer ring (2), at least one row of rolling elements which are arranged between raceways formed on the rings (2, 3) and a ring gear (6) that has a circumference of less than 360° and is fixed to one of the rings (2). The ring gear (6) is formed of a single gear segment (7) which has a circumference substantially equal to the circumference of the ring gear (6) and is provided on its inner or outer peripheral surface with a plurality of meshing means (7b) and fixed only to one of either the inner or outer rings (3) of the rolling bearing (1).

Abstract: Rolling bearing (1) comprising an inner ring (3), an outer ring (2), at least one row of rolling elements which are arranged between raceways made on the rings (2, 3) and an ring gear (6) fixed to one of the rings (2). The ring gear (6) is formed of at least two independent gear segments (7, 8, 9, 10, 11, 12) which are each provided on their inner or outer peripheral surface with a plurality of meshing means (7b, 8b, 9b, 10b, 11b, 12b) and fixed only to one of either the inner or outer rings (3) of the rolling bearing (1), the circumference of the ring gear (6, 20) being substantially equal to the circumference of the combination of the independent gear segments.

Abstract: The invention relates to a Slewing bearing having an inner ring and an outer ring, wherein at least the inner ring or the outer ring is formed as a split ring formed by combining a first split ring and at least one second split ring, wherein each of the split rings is provided with a plurality of mating through-holes and wherein the first split ring and the second split ring are joined by bolts fitted into pairs of corresponding through-holes. It is proposed that at least one of the through-holes in the first split ring has a larger bore diameter than the corresponding through-hole in the second split ring.

Abstract: The roller bearing comprises an inner ring, an outer ring, at least one row of rolling elements which are arranged between the rings in order to form an axial thrust which can transmit axial forces, and a row of rolling elements arranged between the rings in order to form a radial thrust which can transmit radial forces. The inner ring comprises an annular groove which extends towards the interior from an outer surface of the ring, and forms a raceway for the rolling elements of the radial thrust.

Abstract: The roller bearing comprises an inner ring 14, an outer ring 16, at least one row of rolling elements 18, 20, 22 which are arranged between the said rings in order to form an axial thrust which can transmit axial forces, and a row of rolling elements 24 arranged between the said rings in order to form a radial thrust which can transmit radial forces. The inner ring comprises an annular groove 36 which extends towards the interior from an outer surface 14c of the said ring, and forms a raceway for the rolling elements 24 of the radial thrust.
