摘要： It is an object of the present invention to provide a thrust ball bearing which has a large load capacity, can realize thinned wall, and can further withstand a radial load. A pair of raceways (21, 22) include double rows of raceway grooves (23A, 23B) provided along a radial direction on surfaces facing each other. The retainer (40) includes claw-shaped protrusions (42) that protrude from peripheral edges of openings of pockets (41) in a convex manner and are arranged to face each other only in a circumferential direction of the retainer. A maximum width W of the claw-shaped protrusions (42) in the radial direction is smaller than a maximum width L of the raceway grooves (23) in the radial direction.

摘要： A motion guide apparatus is provided which can make a carriage compact without reducing a rated load and an allowable load. The motion guide apparatus includes: a track member (1) and a carriage (2) that moves along the track member (1). A circulation path (7) of the carriage (2) includes a loaded path (C1), a return path (C2) parallel to the loaded path (C1), and a substantially U-shaped turn path (C3) connected to the loaded path (C1) and the return path (C2). At least a part of the turn path (C3) bends in side view in a direction where the loaded path (C1) and the return path (C2) coincide.

摘要： A cage for a ball bearing is optimized for high-speed applications. To reduce weight, the cage is formed by a number of conical blades which collectively form an “X” shape. To add rigidity, a number of gussets are placed between the blades at various circumferential locations. The light weight reduces the centrifugal forces for a given diameter and rotational speed. The rigidity permits the cage to withstand the centrifugal forces without excessive deflection or stress.

摘要： The present invention proposes a deep groove ball bearing, having an outer ring, an inner ring, spherical rollers located between the inner ring and outer ring, and a cage for holding the spherical rollers. In an axial direction, the inner ring has a first inner ring shoulder at a first side, and a second inner ring shoulder at a second side opposite the first side; and a first inner ring shoulder diameter of the first inner ring shoulder is configured to be larger than a second inner ring shoulder diameter of the second inner ring shoulder. The present invention further proposes a differential including the deep groove ball bearing.

摘要： A two-piece plastic ball bearing cage is designed to handle high-speed applications. Posts on one bearing half fit into holes in the other bearing half After the two halves are brought together, ultrasonic vibration is applied to the ends of the posts. The ultrasonic vibration deforms the post end to fit into a widened portion of the holes and welds material, thereby firmly securing the two cage halves to one another.

摘要： The present invention discloses a magnetic rolling bearing capable of reducing the balance radial force of the gear pump, which includes a magnetized inner ring, a rolling body, a cage, and a magnetized outer ring assembly. The inner ring is magnetized to make the inner and outer ring surfaces of the magnetized inner ring have different magnetic properties; the magnetized outer ring assembly consists of four components, namely an upper ring surface of the magnetized outer ring assembly, a lower ring surface of the magnetized outer ring assembly, and two components in left and right. The left and right components are not magnetized, they are connected by recesses and are fixed with bolts, and the four components are alternately connected to form a complete ring.

摘要： A pair of hybrid ball bearings have stainless steel rings and ceramic balls and are configured such that when the first inner ring and the first outer ring are in contact with the first plurality of ceramic balls under zero measuring load and zero mounting load and the second inner ring and the second outer ring are in contact with the second plurality of ceramic balls under zero measuring load and zero mounting load a certain gap exists between either the inner rings or the outer rings. The gap is based on the diameter of the inner ring or on the pitch diameter of the balls and on whether the bearings have an X configuration or an O configuration.
