Metal - Polymer Steel Backed PTFE Oilless Bearing High Strength
1. Product Description
Metal - Polymer Steel Backed PTFE Oilless Bearing High Strength consists of metal backing with PTFE polymer as working layer. The metal backing provides mechanical strength, while the bronze sinter layer provides a strong mechanical bonding between the backing and the bearing lining, the PTFE polymer offers exceptional low friction even under dry condition and the thermoplastic polymer is generally designed to operate with marginal lubrication. The construction promotes dimensional stability and improves the thermal conductivity. This material meets the demanding criteria for long life and trouble-free performance with or without lubrication.
2. Specification
| Load capacity | Static load | 250 N/mm2 | PVvalue limit | Oil lubrication | 70 N/mm2.m/s |
| Dymamic load | 140 N/mm2 | Dry friction | 3.6 N/mm2.m/s |
||
| Oscillating | 60 N/mm2 | Friction coef μ | 0.03~0.20 | ||
| Speed limit | Oil lubrication | 10 m/s | Working temperature | -195℃~+300℃ | |
| Dry friction | 2.5 m/s | Thermal conductivity | 13W/mk | ||
| Coefficient of linear expansion | 11× 10 -6/K |
||||
3. Application
Metal - Polymer Steel Backed PTFE Oilless Bearing High Strength are widely used in hydraulic machinery,building machinery ,marine machinery etc.
4. Advantages
It has good wear and low friction performance over a wide range of loads, speeds and temperatures in dry running conditions, suitable for lubricated applications and for linear, oscillating and rotating movements,even suitable for dry running, low coefficient of friction, lower wear and with good sliding.
