Characteristics
- Applicable motors
MOL MOS Servomotor – – Stepping Motor ○ ○ General-purpose motor ◎ ◎ ◎: Excellent ○: Very good
- Property
MOL MOS Allowable Misalignment ◎ ◎ Electrical insulation ◎ ◎ Allowable operating temperature -20℃ to 80℃ -20℃ to 80℃ ◎: Excellent ○: Very good
- This is an oldham-type flexible coupling.
- Slippage of hubs and a spacer allows large eccentricity and angular misalignment to be accepted.
- The load on the shaft generated by misalignment is small and the burden on the shaft is reduced.
- It has electrical insulation.
- Standard type MOL and short type MOS are available.
