How much do Rubber Rail Pads weigh?
The weight of rubber rail pads is determined by material density, structural design, and dimensional specifications. Standard pads with 7-10mm thickness typically weigh 4.5-6.5 kg/m². Taking a common 300×170×8mm rectangular pad as an example, individual units weigh approximately 280-320 grams, while reinforced pads for heavy-haul railways (12mm thickness) can reach 450-550 grams per unit.
| Rubber Rail Pad | ||
| Technical Parameter | Unit | Value |
| Stiffness | KN | 90-130 |
| Hardness Shore A | ℃ | 72-80 degree |
| Electronic Resistance | Ω | ≥ 106 |
| Tensile Strength before Aging | Mpa | ≥12.5 |
| Elongation before Aging | % | ≥250 |
Weight directly influences performance: each additional 1 kg/m² increases dynamic stiffness by 8-10 kN/mm but reduces vibration attenuation by 3-5%. Lightweight pads developed through micro-foaming technology achieve 15% weight reduction while maintaining equivalent mechanical properties, particularly suitable for weight-sensitive bridge sections.
GNEE RAIL's engineering database reveals a nonlinear relationship between pad weight and service life: when maintaining 5.2-5.8 kg/m², products achieve 6 million load cycles. We precisely control material density according to project requirements, delivering products with ±3% weight tolerance for high consistency.
