Q 1. What is the maximum load rating and deflection of the CM890-60?

A. The CM890-60 is rated to a maximum load of 735 kg with a deflection of 5 mm at that load.

Q 2. What does the 60 Shore A hardness grade mean for this mount's performance?

A. The 60 Shore A medium grade balances vibration isolation against structural support. It sits between the softer 45 Shore A grade (which gives greater deflection and better isolation at lower loads) and the harder 70 Shore A grade (which carries higher loads with less movement), making it the general-purpose choice across a broad band of operating conditions.

Q 3. What applications is the CM890-60 designed for?

A. The CM890-60 is designed for general-purpose mounting of engines, cabs and equipment in construction and earth-moving machinery, operator cabs, off-highway vehicles and agricultural machinery. Its medium grade also suits power generation, marine, railway and mass transit, automotive, and military and defence applications.

Q 4. Can this mount be loaded in more than one direction?

A. Yes. The CM890-60 may be loaded in shear, compression or a combination of both. The cone geometry provides high horizontal stiffness relative to vertical stiffness, controlling movement across multiple axes.

Q 5. What are the key dimensions of the CM890-60?

A. A: 69 mm, B: 54 mm, C: 79 mm, D: 5 mm, E: 16 mm, F: 12 mm, G: 19.7 mm, H: 1.4 mm, J: 89 mm, L: 70 mm.

Q 6. Is this mount suitable for mobile or off-highway machinery?

A. Yes. The cone mount's failsafe design is specifically noted as ideal for mobile applications where dynamic and unpredictable loading is a factor.

Q 7. Are alternative hardness grades or custom specifications available for this mount?

A. Yes. The 45 Shore A grade (CM890-45) and the 70 Shore A grade (CM890-70) are available for applications requiring more compliance or greater load capacity respectively. Stainless steel metalwork, oil-resistant and high-temperature rubber compounds, and additional or custom sizes are also available on request.

Q 8. What if my order arrives damaged or incorrect?

A. WhatsApp us on 07754 288583 with photos of the item and packaging, and we will resolve the issue in line with our returns policy.
