Jiaxing bearing manufacturing co. , LTD. , production of needle roller bearing, needle bearing with fine and long roller (
Roller diameter D 5 mm or less, the L/D 2 or more.
5, L for roller length)
, so the radial structure is compact, its inner diameter size and load capacity at the same time, with other types of bearing outside diameter is small, especially suitable for radial size by a limited amount of supporting result.
According to the use of different occasions, can be used without inner ring of the bearing or needle roller and cage components, at this time to suit the bearing surface of the surface of the shaft and the shell hole directly as inner and outer rolling bearing surface, in order to ensure the load capacity and operation performance and you have the same ring bearing, axis or shell hole hardness on the surface of the raceway, machining accuracy and surface quality should be as a bearing ring raceway.
These bearings can bear radial load only.
Products overview: plane thrust bearing by thrust needle roller or thrust cylindrical roller cage of components and the thrust washer.
Needle roller and cylindrical roller cage to keep and guidance, in conjunction with different types and series of washer, you can configure a number of different combinations.
If the adjacent parts surface is suitable for race, could save the gasket.
Cylindrical roller thrust bearing with needle or ball thrust cage of components and the thrust washer.
Needle roller and cylindrical roller thrust cage to keep and guidance.
With different series of DF thrust bearing washer when used together, can provide bearing configuration with many different combinations.
Due to choose high precision cylindrical roller (
Needle)
Increased the contact length, make the bearings in a small space can be obtained under high load capacity and high stiffness.
Another advantage is that, if the adjacent parts surface is suitable for saves a raceway surface of the gasket, can make the design is compact, DF thrust needle roller bearing and cylindrical roller bearing thrust needle roller and cylindrical roller cylinder for the modification of surface, edge can reduce stress, improve the service life.
Product advantages and usability: needle bearing with fine and long roller (
For 3 ~ 10 times the diameter of the roller length, diameter, generally no more than 5 mm)
, so the radial structure is compact, its inner diameter size and load capacity at the same time, with other types of bearing outside diameter is small, especially suitable for radial installation size limit of the supporting structure.
Needle roller bearing according to the use of different occasions, the machining accuracy and surface quality should be combined with bearing ring, use.
Needle roller bearing is a centripetal needle bearing and thrust bearing parts of the bearing unit.
