Hydraulic Cylinder Extension Cap
Hydraulic cylinder extension cap, in 70 sizes across a Ø50–150 mm bore range. Used in manufacturing and rebuilds.
A longer-bodied version of the gland cap. It increases rod bearing length, giving steadier running against side load and bending.
Sizes are written as bore × rod diameter: 100x50 means a Ø50 mm rod in a Ø100 mm bore.
