Linear Alignment Coupler
Eliminate cylinder alignment problems. Install a Linear Alignment Coupler. Linear Alignment Couplers can reduce rod seal and bearing wear and help prevent binding and erratic movement caused by misalignment. The coupler permits greater tolerance between the cylinder centerline and mating member and works in push or pull applications. Engineers evaluating a connection and maintenance teams investigating wear can review the dimensions and rated loads below.
Linear Alignment Coupler Features:
- Reduces rod seal and bearing wear
- Prevents binding and erratic movement caused by misalignment
- Permits a greater tolerance between cylinder centerline and mating member
- Works equally well in “push” or “pull” applications
