Overview – Transmission Parts BALL;STEEL 111707 Series
The Hitachi BALL;STEEL 111707 is part of a proven family of components used across Hitachi transmission and valve bodies as the steel ball, and several interchangeable part numbers share the same fitment.
Parts Characteristics
A hardened steel ball that acts as a check, detent or bearing element inside a transmission or valve body, holding pressure or locating a spool. It is a tiny, precise part, so a true, round ball keeps the circuit sealed and the spool located – and a worn or wrong one lets pressure bleed away.
Applicable Models & Applications
Fitted to Hitachi transmission positions specifying this steel ball. Match the diameter and grade against your old ball – steel balls differ in how they seat and carry load.
Maintenance & Replacement
Replace balls as a set where they work in a group. A new ball against a worn neighbour seats unevenly and the circuit loses its balance.
Inspect the seat the ball runs on, not just the ball. A perfect ball onto a damaged seat still leaks, and the leak is what drops the pressure.
Confirm the grade matches the specification. A ball that looks right but is the wrong hardness deforms under load and the joint drifts.
Keep the common steel balls for your transmission on the bench. They cost almost nothing, they are load-critical, and a circuit stopped on a ball is a machine waiting on a small part.
Price Reference (USD)
As a reference, the BALL;STEEL 111707 is typically priced between USD 1 and USD 8 depending on configuration, lot size, and current exchange rates.
