A 10 cm dia. hydraulic cylinder on an industrial truck has some eroded areas 1
- 8 mm across and maybe 0.3 mm deep. The pitted areas might not leak a lot by themselves but they may be rough enough to have worn out the old seals which are leaking a lot -- no matter the position of the cylinder, it slides down. The pressure is OK on the inlet to the single acting cylinder.
What could have caused the pitting?
How long would it take for new seals to wear out on the old cylinder? Is there any alternative to rechroming the cylinder? The lift isn't used a whole lot.
