Игольчатый роликовый подшипник, внутренний диаметр 25 мм Caterpillar 0990334

A Needle Roller Bearing is a type of roller bearing that uses cylindrical rollers with a small diameter, which are called needles, instead of the larger balls found in other types of bearings. The needles are held in place by a cage or retainer, which keeps them evenly spaced and prevents them from contacting each other.Attributes:• Has linear contact areas with outer rings to distribute loads on the larger surface area.• Designed to reduce friction and improve efficiency.• Provides high radial stiffness.• Designed to operate in high-temperature environments.Applications:A Needle Roller Bearing supports the high radial load in the Piston.
