Product Desription
1. Production Technical Flow
2. Physical properties of rubber cover
a. Physical properties of rubber cover
Type | Tensile Strength/ MPa | Breaking elongation/ % | Abrasion loss/ mm3 |
LO | ≥14.0 | ≥350 | ≤200 |
DO | ≥16.0 | ≥350 | ≤160 |
Note:LO-used in general oily working conditions.DO-used in high abrasion & oily working conditions. |
After-aging properties of rubber cover(70ºC×168h):
Change rate of tensile strength and breaking elongation are both not more than 25% of before-aging values.
b. Oil resistant properties of rubber cover
Serial number | Test conditions of soak liquid | Volume change rate/% ≤ | |||
Oil number in GB/T1690 | Soak temperature/ºC | Soak time/h | LO | DO | |
1 | #2 oil | 70±2 | 70+0/-1 | +20 | -5 |
2 | #3 oil | 70±2 | 70+0/-1 | +50 | +5 |
3 | #3 oil | 100±2 | 22±0.25 | +50 | +5 |
Note:You only need to choose one of the above three methods. |
