What is the needle roller bearing model with outer diameter 21 and inner diameter 16?
The outer diameter of 21 needle bearings with 16, the market is not available.The outer diameter of 21 needle roller bearings through 15, some models are hk1512.
Needle bearing roller bearings are cylindrical roller, relative to its diameter, the roller is thin and long, hence the name. Although the needle roller bearings with a smaller section, the load bearing capacity of the bearing is still high, with thin and long needle bearing roller (roller diameter of D = 5mm, L/D = 2.5, L roller length), so the radial structure is compact, its diameter and load capacity and other types of bearings at the same time, minimum diameter, especially for the supporting structure of radial installation size limited.
The needle roller bearing model with an outer diameter of 21 and an inner diameter of 16 does not exist.The needle bearing type with an outer diameter of 21 and an inner diameter of 15 is BK1512 or BK1516.The needle bearing type with an outer diameter of 22 and an inner diameter of 16 is BK1612 or BK1616.
