Urethane Gel (N-30, N-15, N-01)

Specifications

How to choose Vibration isolator

Points to check when selecting, with the values for this product (Urethane Gel (N-30, N-15, N-01)).

1. 1. Select hardness suited to load and vibration

   Softer materials provide higher vibration absorption, but under heavy equipment they sink too much and performance drops. Hardness is expressed as Asker C or Durometer E; the listed products have a Durometer E value of 20 to 30. Values measured by different methods cannot be compared directly, so compare values measured by the same method.

2. 2. Check the allowable load per piece

   Divide the equipment weight by the number of mounting points to obtain the load per piece. Confirm that this value is below the allowable load. For equipment with an off-center center of gravity, judge by the load on the heaviest point. Exceeding the allowable load causes permanent set and degradation of vibration isolation performance.

3. 3. Determine size to match the contact surface

   This product: Size (length × width) 400×400×5, 200×200×5 mm

   Sheet products can be cut to the required size from sizes such as 400 × 400 mm or 200 × 200 mm. For pads and mats, select dimensions that fit the equipment feet or the contact area of the base. Round products are available from an outer diameter of about 30 mm, and square products are available in sizes such as 30 to 50 mm square.

4. 4. Check sinking and height by thickness

   Thicker products can deform more, giving greater margin for shock absorption. On the other hand, installation height increases and equipment may become more prone to wobbling. The listed products are 5 mm thick. Check the installation space height together with equipment stability.

5. 5. Check material and oil and solvent resistance

   Urethane gel has ultra-low elasticity and excellent absorption, but some listed products cannot be in continuous contact with oils or solvents. Confirm suitability before use near machinery where oil is scattered. For fall prevention applications, also check whether the product is adhesive type.

6. 6. Use within the operating temperature range

   This product: Operating Temperature Range -20〜80 ℃

   Rubber and gel become harder at low temperatures and soften or lose adhesive strength at high temperatures, which changes vibration isolation performance. When used near heat-generating equipment, outdoors, or in refrigerated environments, confirm that the installation temperature is within the operating temperature range.
