PKW250M-U-SCG,PK 低壓槓桿缸

PKW250M-U-SCG

PK Low pressure lever cylinder

Description
  • The unique connecting rod mechanism can convert the linear motion of the piston of the hydraulic cylinder into a clamping rotary motion, thereby achieving barrier-free clamping.
  • Special one-piece molding design combined with forging, the overall strength and durability are greatly improved.
  • Strict protection design is adopted, which can effectively prevent the infiltration of high-pressure coolant.
  • Using high-performance corrosion-resistant protective materials, even if the coolant is used for a long time, its durability and sealing will not be damaged.
  • 合金缸本體,適用於焊接用夾具或超大型夾具。
  • There are also a variety of optional equipment, which absolutely meets your needs. Special specifications can also be tailor-made for you.

Precautions
(1) Using Pressure70kg/c㎡為最大極限壓力,請以Operating Pressure參考使用。
Precautions
(1) The capacity curve shows the relationship between clamping force and Operating Pressure.
(2) The reference pressure under the capacity curve will have a slight error due to friction or pressure. Use 80% of the reference clamping force as the recommended value.
(3) The pressure plate length of this capacity curve is the length of the standard connection pressure plate.

Precautions
(1) Material: S45C (surface dyed black).
(2) Do not apply force other than the axial direction of the piston rod, otherwise it will cause extreme bending stress on the piston rod, which must be absolutely forbidden.
