Consumables and important parts for safety

Aren't you in trouble with something like this?

All press components have their life (fatigue and degradation).
Using beyond the life may cause unintended machine failure or unexpected accident.

We propose to replace the components as in below table depending on your applications (overall term, working period, operating times etc.).

No Maintenance/replacement parts Application Replacing interval and remarks
1 Solenoid valve Clutch brake 3 years or 5 million times, or immediate if long emergency brake time or air leakage from valve
2 Control relay Clutch brake control 3 years or 5 million times, or immediate if long emergency brake time or air leakage from valve
3 O-ring Clutch brake 3 to 5 years
4 Control relay (miniature) Safety device control 2 years or 5 million times
5 Limit switch Rotary cam 5 years or 10 million times
6 Stroking selector key switch Stroking selector 3 to 5 years depending on maintenance condition
7 Run button Machine operation 3 years or 5 million times
8 Emergency stop button Emergency stop 3 years or 5 million times
9 Coupling Encoder 3 to 5 years
10 Light guard Emergency stop 3 to 5 years

Note 1: Life span or times described above are all of approximate estimation and subject to change depending on press application, environment, maintenance etc. Note that values are not of our guarantee.


We recommend you to have inventories of spare parts.

  • Especially keep those parts that require long lead time and frequent replacement including such consumables as oil filters etc.
  • For avoiding a sudden machine stop, it is important to prepare for risks through preventive maintenance and retrofitting in accordance with increased operation hours.


You can minimize stopping hours of the machine. At the same time, this will help you implement preventive maintenance:

  • Maintaining "safety," "quality," and "accuracy" for longer machine life.
  • Avoiding sudden machine failures to realize higher operation rates.
  • Reducing damage from failures through periodical parts replacement.
