Product description of KOYO Bearing JR15x20x12

KOYO Bearing JR15x20x12, Needle roller bearings Inner rings Metric series. Needle roller bearings have a small cross-sectional height therefore contribute to keeping the overall machine lightweight and compact. As such, they are used across a broad scope, including cars, motorcycles, electric machinery, machine tools, aerospace devices, office equipment and other industrial machinery.

supplies both inner rings for needle roller bearings and needle rollers as separate needle roller bearing components.

Inner rings are typically combined with needle roller and cage assemblies or drawn cup needle roller bearings in applications where the shaft cannot be hardened and ground.

KOYO Bearing JR15x20x12, Needle roller bearings Inner rings Metric series. Needle rollers can be used to design full complement bearing arrangements for low-speed or oscillating applications. These compact bearing arrangements have a very high load carrying capacity when compared to bearings with a cage and are economical, provided the shaft and housing bore can serve as raceways (Raceways on shafts and in housings). KOYO needle roller bearings are bearings with cylindrical rollers that are small in diameter relative to their length. The modified roller/raceway profile prevents stress peaks to extend bearing service life. KOYO supplies needle roller bearings in many different designs, series and in a wide range of sizes, which makes them appropriate for a wide variety of operating conditions and applications.

KOYO Bearing JR15x20x12, Needle roller bearings Inner rings Metric series. The invention relates to a needle bearing, installed on textile mechanism for taking the effect of aligning when axial centers are not parallel, belonging to textile bearing technology area, comprising bearing body. The bearing body comprises inner ring, outer ring formed with spherical face and needle bracket with needles set between inner and outer rings. It is characterized in that a corresponding hole is set at said outer ring and locating mechanism of outer ring, which is used to prevent the outer ring moving on the circle direction in using condition, is set on said corresponding hole. Merits are because the locating mechanism of outer ring is added to prevent outer ring moving on the circle direction in using condition, the outer ring can not be heated to destroy and the service life is prolonged; because by fixed cap lubricating oil is supplied to needles between inner and outer rings through the corresponding hole, the working effect of needle is improved so as to prolong the whole service life of needle bearing.
