Steel Bronze Powder with POM Marginal Bearings
Steel Bronze Powder with POM Marginal Bearings(YF-20)
Features
Suitable for rotating and oscillating movement, less maintenance requirements due to the long re-lubrication intervals, lower wear, lower susceptibility to edge loading, no absorption of water and therefore no swelling, good damping behaviours, good resistance to shock loads.
Structure
 |
1.POM thickness 0.30~0.50 mm, it provides high wear resistance and low friction even with only minute volume of lubricant are supplied, this bearing surface carries a pattern of circular indents which should be filled with grease on assembly of the bearing.
2.Sintered bronze powder thickness 0.20-0.35mm, provides max. thermal conductivity away from the bearing surface, also serves as a reservoir for the resin mixture.
3.Low-carbon steel, provides exceptionally high load carrying capacity, excellent heat dissipation.
4.Copper/Tin plating thickness 0.002mm
