Fritex-B
Properties
Multilayer bushing (dry Sliding Bearings) Fritex-B is a three layer composite product.
Materials
| Layer | Average analyses of the material | Thickness of layer |
| Sliding layer | PTFE Fabric | 0,40 mm |
| Intermediate layer | Special Adhesive | 60 μm |
| Supporting shell |
Bronze CuSn8P Cu = Rest Sn = 7,5 - 8,5 % P = 0,4 % Max |
0.50 - 2,70 mm (Depending on Dim. of the Bearing) |
Operating Conditions
| Dry | Very Good |
| Oil | Fair |
| Grease | Fair |
| Water | Fair |
| Process fluid | Fair |
Characteristics
Fritex-B Structure combines in the best way the mechanical strength and the chemical resistance of bronze, and PTFE low friction characteristics. The performance given without lubricants are the following:
| ·Working surface acceptable specific static pressure until 200 N/mm2 |
| ·Working surface acceptable specific dynamic pressure until 150 N/mm2 |
| ·Maximum sliding speed: 1,5 m/s (300 fpm) |
| ·Working temperature from: -100°C to +260° C (-148°F to +500°F) |
| ·Friction factor from 0,03 ÷ 0,15 |
| ·High chemical resistance to industrial fluids and gases. We recommend to make previous test for new application / project. |
