About this part
What it is and why it is made that way
Linkage arms transfer a movement from one point to another without a heavy machined assembly. Stamping gives a consistent pivot boss and a light, stiff arm, and the pivot bore can be reamed after pressing so it runs on a bearing rather than on a sheet-metal edge. Common in access equipment, actuators and small machinery.
- Formed pivot boss with a reamed bore option
- Rolled edges on arms that swing near a person
- Consistent arm length across the batch
- Optional bushing pressed into the pivot boss
