Product Description
PVB010 Steel Back PTFE Lined DU Bearing
PVB010 metal polymer self-lubricating plain bushing features a low carbon steel backing with sintered bronze powder and PTFE mixture. This composite plain bearing is also known as coated self-lubricating bearing, DU bushing, metal polymer plain bearing, PTFE lined dry sliding bearing, SF-1 oilless bearing, and LFB oil free bushes.
Material Structure
- PTFE/Pb mixture (0.01-0.03mm): Sliding layer providing excellent initial transfer film that coats mating surfaces with homogeneous oxide type solid lubricant
- Porous bronze (0.2-0.3mm): Maximizes thermal conductivity away from bearing surface and serves as reservoir for PTFE-lead mixture
- Low-carbon steel backing (0.7-2.3mm): Provides fundamental structural support with exceptionally high load capacity and excellent heat dissipation
- Tin-plating (0.005mm) or copper plating (0.008mm): Ensures good corrosion resistance
Key Characteristics
- Excellent wear and friction performance across wide range of loads, speeds, and temperatures without oil
- Performs well with lubrication when required
- Maintenance-free operation with extended service life
