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 UTV double row tapered wheel bearing assembly may include a first inner diameter race, a second inner diameter race axially offset from the first inner diameter race, and an outer diameter race radially offset from the first inner diameter race and the second inner diameter race, the outer diameter race formed as a single integral member. A first ring of rollers may be disposed between the outer diameter race and the first inner diameter race. A second ring of rollers may be disposed between the outer diameter race and the second inner diameter race. A first shield may be coupled to a first axial face of the bearing, and a second shield may be coupled to the second axial face of the bearing.

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 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.

An end play measurement apparatus is provided that measures end play of a tapered roller bearing of a gear unit. The gear unit supports a large-gear shaft, with which a gear is fitted, via the tapered roller bearing. The end play measurement apparatus includes a power generation unit, which is fixed to the large-gear shaft and generates power to move the gear unit backward and forward in the axial direction, a position change unit, which is interposed between the power generation unit and the gear unit and changes the axial position of the gear unit by using the power of the power generation unit, and a booster mechanism, which has a free end that receives the power of the power generation unit to boost the power.

A bearing structure of a turbocharger includes a rotor shaft, two angular ball bearings, a retainer, a housing, and an oil film damper. Each of the angular ball bearings includes an inner ring and an outer ring that are supported in relatively rotatable manner. The rotor shaft is inserted into the inner ring. The retainer holds the outer ring. The housing houses therein the rotor shaft, the angular ball bearings, and the retainer to constitute a bearing housing. The oil film damper is formed of oil in a film state and is interposed between the inner ring and an outer peripheral surface of the rotor shaft. The inner ring is configured to rotate with rotation of the rotor shaft via the oil film damper.

A method for servicing a gas turbine engine includes providing access from a forward section of the gas turbine engine to a gearbox contained within a bearing compartment.

Systems and methods for an interaxle differential (IAD) are provided. In one example, the IAD comprises a locking assembly that includes a friction clutch, the friction clutch includes a clutch pack that comprises plurality of plates configured to engage and disengage to inhibit and permit speed differentiation between a first axle differential and a second axle differential. The IAD further includes a supply lubrication passage that comprises an inlet that receives a lubricant from an enclosure surrounding an input gear of an axle differential and a first outlet flowing the lubricant to a gear coupled to the clutch pack.

A method for spin set bearing setting verification in a preload state on a shaft. An inertia wheel may be disposed on the shaft. The inertia wheel or the shaft is rotated. A first rotational speed is measured at a first time. The inertia wheel may decelerate over time to achieve a second rotational speed measured at a second time. The second speed is less than first speed. The change in time between the first time and the second time is measured. The bearing setting may be adjusted if the change in time is outside a predetermined time range. The bearing setting may remain unchanged if the change in time is within a predetermined time range.

A bearing assembly for a turbocharger includes a turbine wheel-side ball bearing at a first axial end of a tubular body, a compressor impeller-side ball bearing at a second axial end of the tubular body, and a bearing housing. The bearing housing includes a first opposed wall opposed to an axially outer side of an outer race of the turbine wheel-side ball bearing, and a second opposed wall opposed to an axially outer side of an outer race of the compressor impeller-side ball bearing. The outer race of the turbine wheel-side ball bearing and the outer race of the compressor impeller-side ball bearing have axially outer end surfaces which are axially outwardly displaced from respective axial end surfaces of the tubular body so that oil films are present between the respective outer races and the corresponding opposed walls.
