The Chain Unit is comprised of an Arm Cylinder Bracket, Ball Joint, and Air Cylinder. Together, they are the largest component assembly and perform the major function of engaging and disengaging the chain wheel to the drive tires.
- Welded & Gusseted cylinder brackets provide strength and durability in the harshest applications.
- Greaseable Arm Pivots provide longer life by keeping contaminates out while promoting smooth consistent operation.
- Needle Bearings distribute force evenly extending service as opposed to ball bearings that absorb force on a small point of contact with the bearing journal. Sustains high shock loads better!
