Description:Needle Roller Thrust Bearings provide a high degree of stiffness within a minimum axial space. It has a smaller cross-section than a standard thrust bearing for use in restricted spaces.These bearings accommodate heavy axial loads and peak loads due to the small diameter deviation of the rollers within one assembly.Thrust Bearings can be combined with washers in applications where adjacent components cannot serve as raceways.Made of hardened spring steel, both faces of the washers are polished and can be used as raceways.Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.

The basic design of these products is essentially that of a conventional rolling bearing, except that they have a thick-walled outer ring. Stud type track rollers have a shaft stud at one end. In the majority of applications, the outer ring is subjected to circumferential load, i.e. the outer ring rotates while the inner ring or stud remains stationary. The thick-walled outer ring prevents excessive deformation of the track roller and ensures that the rolling element set is uniformly loadedSpecificationsRoller diameter: 72 mmBore diameter: 35 mmRoller width: 28 mmRoller shape: CrownedBearing element: Needle RollersClosure type: SealedOperating temperature range: -30 to +100 °CRadial dynamic load capacity: 7400 lbfRadial static load capacity: 16400 lbfMaximum rpm: 1400 RPMLubrication hole location: Inner RingFinish/coating: Uncoated.

Description:Material - The sprocket is made of C45 carbon steel with a full black oxide coating, which is rust-proof. The tooth part uses high-temperature quenching heat treatment, high hardness, wear resistance, a long service life, and is easy to use.Design - Each roller sprocket is equipped with strong teeth to lock the chain well. The round hole has set screws and forms a 90-degree angle with the set screw after installation, which can fix the shaft and prevent it from slipping.Installation - Chain Sprockets are normally mounted in a fixed position on a fixed shaft. The chain sprocket should not rotate at a greater speed than is allowable for drive sprockets of the same size. It is suggested that chain sprockets have at least three teeth in mesh with the chain.
