DX – Steel Bronze Powder with POM Marginal Bearings
FEATURES
- Suitable for rotating and oscillating
- movement
- Less maintenance requirements due to the long re-lubrication intervals
- Low wear rate
- Lower wear
- Lower susceptibility to edge loading
- No absorption of water and therefore no swelling.
- Good damping behaviours
- Good resistance to shock loads
PRODUCT STRUCTURE
- POM thickness 0.30~0.50mm, provides high wear resistance and low friction even with only a minute volume of lubricant supplied, this bearing surface carries a pattern of circular indents which should be filled with grease on assembly of the bearing.
- 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.
- Low-Carbon Steel, provides exceptionally high load carrying capacity, excellent heat dissipation.
- 4.Copper/Tin plating thickness 0.002mm, provides good corrosion resistance.
