Example of how to order an electric cylinder (SFK linear unit and SIMOTICS S-1FK7 motor)

Requirement:

• Average force F_m: 400 N (89.9 lb_f)
• Precalculated: F_mL = 380 N (85.4 lb_f)
• Max. velocity: 280 mm/s (11 in/s)
• Service life: 2000 km
• Stroke: 300 mm (11.8 in)
• Parallel arrangement of 1FK7022 motor and linear unit.
• The electric cylinder must be supported by a swivel flange.
• The customer will assemble the linear unit and the motor.

Solution:

• Step 1:
  Type CASM 40 BS is selected from the table of CASM-40 linear units:
  • F_m = 640 N (144 lb_f)
  • V_max = 300 mm/s (11.8 in/s)
  • Stroke = 100 to 600 mm (3.94 to 23.6 in)

All further steps are based on the information supplied about CASM electric cylinders on SKF's website.

• Step 2:
  Check the service life in the document "CASM 40 linear units".
  The service life ("lifetime") diagram shows that the service life with F_mL =  380 N (85.4 lb_f) is calculated to be 2000 km.
• Step 3:
  Work out the correct order number from the document "CASM 40 linear units".
  CASM 40 BS has been selected with:
• Stroke: 300 mm (11.8 in)
• Motor, adapter and attachment parts separate (assembly by customer)

The order number for the linear unit is thus: CASM-40-BS-0300AA-000

• Step 4:
  Order number for the adapter, see "CASM–40 Siemens motors and adapters"

Order number for parallel adapter kit for CASM–40 and Siemens 1FK7022 motor: ZBE–375541

• Step 5:
  Order number for swivel flange, see "CASM–40 Accessories": ZBE-375504-4
