A dual-bearing reel, includes a reel body, a spool, a spool shaft, an adjustment member, and an operating lever. The spool is rotatable relative to the reel body. The spool shaft is configured to integrally rotate with the spool. The adjustment member is attached to the reel body and configured to adjust a braking force that brakes the rotation of the spool shaft. The operating lever is detachably attached to the adjustment member so as to extend in a radial direction, and configured to be positionally adjusted in a circumferential direction relative to the adjustment member.

A transmission device for a power-driven cutting tool includes a base, a transmission component, a linking component, a shaft component and a link component. The base has a through cavity, a sleeve and a receiving portion. The transmission component is penetratingly disposed in the through cavity, so as to couple the transmission component and the base together. The linking component is penetratingly disposed in the sleeve, so as to couple the linking component and the base together. The shaft component and the link component are disposed in the base. A power source drives the linking component and thereby sequentially drives the shaft component, link component, and transmission component, allowing a cutter of the power-driven cutting tool to undergo reciprocating displacements along a linear path for performing a cutting operation. The transmission device features enhanced structural rigidity, allowing the cutter to move back and forth along a linear track.

A bearing cage segment for a rolling-element bearing includes at least one sliding surface on which a surface of at least one rolling element of the rolling-element bearing is rotatable, a first support element, such as an axial projection on an axial side of the cage segment having a radially open radially facing channel, at a first radial position for supporting a first band section of a band clamp during an assembling of the rolling-element bearing, and at least one second support element at a second radial position different from the first radial position for supporting a second band section of the band clamp.

A bearing support includes at least one sliding bearing defined by the bearing support and/or at least one rolling-element bearing having an outer raceway defined by the bearing support. The bearing support is formed from a fiber-plastic composite and includes an integrally formed sliding surface of the sliding bearing and/or an integrally formed raceway for rolling elements of the rolling-element bearing, and the fiber-plastic composite includes a matrix into which spatially oriented sliding fibers, for example, PTFE fibers, are embedded in a region of the sliding surface of the sliding bearing and/or a region of the raceway of the rolling-element bearing.

A bearing assembly for an electrical generator includes a frame, a bearing liner and a ring. The frame is configured to connect with a housing of an electrical generator. The frame includes a frame opening and is made from a first material. The bearing liner connects with the frame. The bearing liner is made from a second material, which is dissimilar from the first material. At least a portion of the bearing liner passes through the frame opening. The ring surrounds the bearing liner. The ring contacts the frame and the bearing liner and maintains a clearance between the portion of the bearing liner passing through the frame opening and the frame.

A fuel-saving apparatus using a variable preload of vehicle bearings is provided. The fuel-saving apparatus includes a housing that supports a driving shaft of a vehicle, a bearing that is mounted in the housing and rotatably supports the driving shaft, and a variable preload unit that is provided at the housing or a side adjacent to the housing and applies a preload to an outer wheel or an inner wheel of the bearing. The fuel-saving apparatus using such a variable preload may reduce a driving load acting on the driving shaft by a fixed preload acting by the bearing, thereby reducing the driving load of an engine and saving fuel.

A high-speed low runout spindle assembly is provided. The spindle assembly includes a friction drive wheel configured to be coupled to an output shaft of a motor. The friction drive wheel is configured and disposed to directly contact a shank of a bit. A set of bearings is configured to contact the shank of the bit. A bit clamp assembly includes a clamp bearing having a central through-hole dimensioned to accept a lower portion of the shank of the bit. The bit clamp assembly is configured to hold the bit in contact with the set of bearings.

A bearing structure of a turbocharger includes a rotor shaft, a ball bearing, and a housing. An inner ring of the ball bearing has the rotor shaft inserted therein. The oil film damper is formed between the inner ring and an outer peripheral surface of the rotor shaft. The inner ring rotates with rotation of the rotor shaft via the oil film damper. An oil discharge path for scattering oil discharged from the oil film damper radially outside, is provided at least either on one end surface of the inner ring in an axial direction or on an opposing surface opposed to the inner ring, of a collar. The oil discharge path is formed of a groove that is arranged in a manner to be gradually apart from the oil film damper in the axial direction as going radially outside.
