| DU-1B Steel-based oil bearing |
| MATERIAL STRUCTURE |
|
|
|
1. PTFE/Pb composition, 0.01-0.03mm, anti-abrasion material, which will form a lubricating film during operation.
2. Bronze powder layer, 0.2-0.35mm, which further strengthen the combination of the bronze plate and PTFE layer and transfer the heat more quickly.
3. Bronze plate, bear high load and transfer heat, anti-corrosion. |

| 应用特点 APPLICATION CHARACTER |
Besides of owns characteristics of DU-1, DU-1B is good at the follows:
Bronze plate owns self-lubricating performance, which can be used in the components that are difficult to add oil, so that the part owns letter anti-corrosive characteristic that HTB-1. The products can be widely applied in chemical environment or port heavy machine, marine machine steel industry etc. Moreover, it can be mated with steel bushing or be made with flange, and the two surfaces are all do works. |
