Advanced OKADA technology eliminates the need for an accumulator without affecting the hydraulic apparatus on the carrier machine, reducing both maintenance costs and downtime.
Precision machining processes and strict Okada quality control are used to produce all main breaker components. There is no need for complete assembly replacements and the use of high precision parts equate to economical, labor-saving rebuilds of your Okada breaker.

Simple, proven internal breaker design and side plates are used, making the Okada breaker more cost effective, reducing maintenance time & costs and delivering greater operation uptime!
With scheduled routine maintenance & proper lubrication 4,000-6,000 hours of operation can be achieved without replacing major components
Lower overall operating costs & TCO
Used to reduce pressure spikes in supply and return lines to protect the carrier hydraulic system. The high pressure accumulator is field repairable without removing the breaker from its mountings. Breakers under 4000 lbs. do not require accumulators.
Cup seals are utilized to secure the flow in the oil and gas chambers.
Cushions piston on the upstroke, eliminating the need for shock absorbers. Increases the piston down stroke force.
A central grease port with internal grease passage allows you to easily adapt the hammer to most Auto Lube systems.
Choice of moil, chisel, blunt and special application tools.
Travels through one machined piece (no misalignment). The long stroke design reduces shock loads and vibration, which can cause operator fatigue and machine stress. Okada breakers have the highest tolerance to high operational back pressures available without negative operational effects.
Heavy dual chisel set pins in many Okada models offer extended service life.
