Materials: ST14 steel with chrome steel GCr15

Weight: 0.0015KG

Lead Time: 3-5 days

Specification

HK0408-B miniature needle roller bearings are stamped outer ring needle roller bearings without an inner ring, featuring a steel plate cage. They offer characteristics such as a low radial cross-sectional height, high load-carrying capacity, high rigidity, and high limiting speed (up to 42,500 rpm with oil lubrication). These bearings are suitable for mechanical components with limited space and high load-carrying requirements.

Product Introduction:

Drawn cup needle roller bearing is precisely stamped with thin steel plate, which has small structural space and large load capacity. It is suitable for occasions where installation space is limited and housing holes are not suitable for raceway. Further axial positioning is not necessary after pressing into the bearing seat hole.


Product Type:

Sealed Drawn cup needle roller bearing with sealing ring seal, under normal working conditions, can protect the bearing from debris intrusion and grease leakage. Therefore, it can be operated for a long time in the range of -20℃-120℃. If suitable grease can be added in time or short-term use, it can be used at +130℃.

The sealing ring is made of synthetic rubber, with good lip elasticity and steel plate lining core, strong mechanical rigidity. In addition, the sealing ring plays an axial guiding role on the retaining rack.

Application fields

HK needle roller bearings are applicable to a wide range of industrial equipment, including shoe eye machines, vertical reducers, forestry machinery, etc. Their high dynamic load and static load characteristics make them perform exceptionally well in industrial mechanical transmission systems. In addition, HK needle roller bearings are also commonly used in low-speed heavy-load conditions, especially in cases where the shaft surface cannot be hardened. They can be used in conjunction with IR type inner rings.
