Forged Housing
1

The Forged Housing (Body)

PTFE liners (SA..C series) offer dry, self-lubricating operation. Standard steel-to-steel designs require scheduled lubrication.
2

The Spherical Inner Ring (Ball)

The pivoting heart of the joint. Standardized to 440C Martensitic Stainless Steel and vacuum heat-treated to HRC 58. Extreme hardness prevents galloping and wear.

The Load Race (Liner)

PTFE liners (SA..C series) offer dry, self-lubricating operation. Standard steel-to-steel designs require scheduled lubrication.

Where Stainless Rod Ends Are Used

LINOX distributes to equipment OEMs worldwide. Our stainless rod end bearings outlast standard chromoly or zinc-plated variants in demanding dynamic environments.

Hydraulic Cylinders

Mounted to the end of pneumatic or hydraulic cylinder rods to prevent corrosion and ensure exact positioning.

Marine Actuators

Used extensively in yacht rigging and steering linkages. 316L grade employed to survive constant salt-spray.

Food Filling Machines

Utilized in nozzle lifting mechanisms. The stainless surface allows for standard Washdown (CIP) procedures.

Grade Selection

The housing material dictates your equipment's lifespan. We forge from solid billets of three distinct alloys.

304

Food / Standard Grade

General-purpose austenitic grade offering excellent resistance to oxidation, high humidity, and standard food-safe cleaning agents without rusting.

316

Marine / Severe Grade

Molybdenum addition gives massive chloride resistance. Absolutely required for boat rigging, chemical plants, and prolonged salt-spray exposure.

PH

17-4PH / High Load

General-purpose austenitic grade offering excellent resistance to oxidation, high humidity, and standard food-safe cleaning agents without rusting.

Technical FAQ

Answers regarding our spherical tolerances, dimensional standards, and custom threading capabilities.

Difference between Series E and Series K?
Series E follows ISO 12240-4 dim-E and is slightly narrower in the inner ring. Series K follows dim-K, which is broader and commonly features a bronze liner, making it capable of wider articulation angles.
Do you supply 17-4PH inner balls standard?
No, 440C stainless steel is our standard for the spherical inner ring because of its excellent HRC58 hardness. 17-4PH is available upon request for specific high-strength custom aerospace orders.
Can I customize the Thread Pitch?
Absolutely. If your hydraulic cylinder requires an imperial UNF thread on a metric body (or vice versa), we can CNC machine custom thread pitches for direct drop-in replacement.
