Product Overview
Fixed Type Simple structure, commonly used in the mechanism to absorb impact energy. The product is not adjustable. Different buffering characteristics can be obtained by changing the size of the internaloverflow hole, the number and position of the overflow hole.
Depending on different collision velocities, there are high speed (H), medium speed (M),and low speed (L). There are single hole overflow type and multiple hole overflow type according to the change in the overflow area.

The advantages of using Fixed Type:
1. Improve production efficiency: equipment can be operated at high frequency and high speed to improve production efficiency because the Fixed Type can stop the impact object smoothly.
2. Extend mechanical life: the buffer can absorb the energy generated by the impact, greatly reduce the impact and vibration caused by the object to the machine, and avoid damage due to impact vibration.
3. Improve product quality: the buffer eliminates the shock caused by impact objects and the damaging impact, allowing the smooth operation of the machine and equipment, and improving the product quality.
4. Significantly reduce noise, and provide a quiet working environment.
5. Improve the safety of mechanical running.

Precautions
1. Fixed Type, Do not exceed the specified locking torque value during installation as shown in the following table for details:
Coarse Outer Diameter (mm)M4ⅹ0.5M6ⅹ0.75M8ⅹ1.0M10ⅹ1.0M12ⅹ1.0M14ⅹ1.5M20ⅹ1.5M25ⅹ1.5M36ⅹ1.5M42ⅹ1.5
Tightening torque of nut (N.m)0.350.853.97.87.89.829.44998392

2. Fixed Type, Pay attention to check whether the head circlip is off.
■ Overloaded buffer will cause abnormal increase in the internal pressure of the buffer tube, making the head circlip off, and internal parts may pop up and cause injury.
■ When the buffer with the head circlip is working, please keep your face and other parts away from it.

3. Fixed Type, Please pay attention to the splash of the broken buffer head due to impact.
■ Overload use will cause damage to the head, resulting in injury.
■ It is recommended to install an anti-splashing cover.

4. Fixed Type, Please pay attention to lateral misalignment load and lateral misalignment angle.
■ When the lateral misalignment load exceeds ±2.5 degrees, it will cause piston rod bending, bad reset, and internal lateral misalignment friction, resulting in performance degradation and even product breakage.
Please aim at the center line of the buffer piston rod for impact. (If the lateral misalignment angle is greater than ±2.5 degrees, please use the angular misalignment absorber (the range of lateral misalignment:± within 10 degrees)

5. Fixed Type, Operating Temperature Range
■ Please use the buffer within the specified temperature range.
▪ Use outside the specified range will reduce the life of the seal packing and the pressure accumulating sponge, and cause the buffer to break.

6. Fixed Type, Operating Environment Requirements
■ Please do not use it under medium or high pressure in a vacuum environment.
■ Keep the guide shaft clean, and avoid cutting powder, cutting fluid, water, etc. from being attached to the guide shaft, otherwise it will cause seal damage, oil leakage, poor buffer action, and buffer damage.
※ If you need to use it in the cutting fluid environment, please choose Misumi’s cutting fluid resistant buffer series products. See Misumi's official website.
 
7. Fixed Type, The buffering oil inside the buffer will cause pollution to the environment, and can not be handled at will. Please follow the pollutant treatment method for treatment.

8. Fixed Type, To prevent the buffer from increasing lateral load, the distance between the installation position of the buffer and the fulcrum should be equal to or greater than 6 times of the buffer stroke.
And when the side load and the buffer center line form an angle of 5°, the absorbed energy is the maximum.
