- Protection Additives: Anti-ozonant wax and chemical antioxidant system for extended service life
- Bonding System: Chemically bonded rubber-to-metal interface exceeding bulk rubber strength
- EN 45545-2 Option: Halogen-free flame retardant meeting smoke toxicity requirements (railway grade)
Every batch produced under ISO 9001:2015 QMS with full material traceability. Certificates of conformance and material test reports available upon request.
Installation Guidelines
- Inspect on arrival: Verify part number 227-0172. Check for transit damage or surface defects — reject any visually non-conforming component.
- Clean mating surfaces: Remove all rust, old rubber fragments, grease, and paint. Flat tolerance within 0.5 mm.
- Align correctly: Follow assembly drawing orientation. Incorrect orientation can cause premature failure.
- Torque fasteners: Use calibrated torque wrench and cross-pattern tightening sequence per OEM specification.
- Post-install check: Visual inspection for correct seating. Run equipment at low speed to verify absence of abnormal noise or vibration.
