The Okada TOP90 2000 foot-pounds class hydraulic breaker has an accumulator that is used to reduce pressure spikes in supply and return lines to protect the carrier hydraulic system.
Its cup seals are utilized to secure the flow in the oil and gas chambers. The nitrogen gas cushions the piston on the upstroke, eliminating the need for shock absorbers, which increases the piston down stroke force.
A central grease port with internal grease passage allows users to adapt the hammer to most Auto Lube systems. The piston travel/long stroke design travels through one machined piece (no misalignment).
The long stroke design reduces shock loads and vibration.
