Marine & Offshore
Corrosion-resistant linkage components for salt spray, washdown, and harsh duty cycles.
316 stainless recommended for salt spray and washdown conditions
Maintenance-free (PTFE-lined) options to reduce downtime and lubrication needs
Optional 2RS sealing for added protection against dust and splash (size dependent)
Fast selection and replacement support: match by drawing, part number, or key dimensions
Built for the Ocean
What typically fails in marine environments
Corrosion & pitting
Salt spray and moisture accelerate corrosion and pitting, especially on exposed joints.
Prioritize 316 stainless, confirm exposure and cleaning routine.
Contamination ingress
Dust, splash, and debris increase wear and can cause binding over time.
Consider 2RS sealing and appropriate material selection.
Maintenance gaps
Offshore access is limited - missed lubrication intervals lead to downtime.
Specify maintenance-free (PTFE-lined) where possible.
Recommended solution set (3-part system)
Stainless Steel Spherical Plain Bearings (GE / GEG)
Self-aligning bearings for pivots and linkages with angular movement.
Recommended for marine: 316 + maintenance-free (PTFE), optional 2RS where available.
Stainless Steel Rod Ends (POS / PHS / SA / SI)
Rod ends for adjustable linkage connections (male/female thread options).
Recommended for marine: 316 + maintenance-free (PTFE) to minimize service needs.
High Misalignment Spacers
Improve achievable misalignment angle and simplify assembly alignment.
Recommended for marine: specify with rod ends to reduce binding under misalignment.
Marine selection guide (fast rules)
Fast rules for configuring your linkage.
If exposure includes salt spray / washdown,
start with 316 stainless.
If maintenance access is limited,
choose maintenance-free (PTFE-lined).
If contamination risk is high,
consider 2RS sealing (availability depends on size).
If wear is the dominant concern,
evaluate 420/440C but confirm corrosion exposure first.
Default marine configuration
"System approach: Bearings + Rod Ends + Misalignment Spacers for stable linkage motion."
Material selection for offshore conditions
304 Stainless
General corrosion resistance and value
Mild humidity, sheltered installations.
For marine spray and washdown, 316 is preferred.
316 Stainless (Marine Grade)
Stronger corrosion resistance
Offshore, coastal, cleaning chemicals, splash exposure.
The most common marine default.
420 Stainless
Higher hardness potential
Wear is dominant and corrosion exposure is moderate.
Confirm environment - 316 may be safer for corrosion.
440C Stainless
High hardness and wear resistance
High wear and controlled corrosion exposure.
Select based on the real environment and maintenance plan.
Protection & maintenance strategy
Maintenance-free (recommended)
- Reduced lubrication needs
- More consistent operation where access is limited
- Ideal for offshore and hard-to-service locations
Lubricatable (available)
- Suitable when scheduled lubrication is reliable
- Can be preferred under specific load/duty conditions
- Specify your maintenance plan in the RFQ
Sealing note: 2RS double seals help reduce ingress in splash/dust environments. Availability varies by size - confirm in the size table or via quote.
Typical marine & offshore applications
Steering & linkage systems
Misalignment compensation and stable pivot motion.

Frequently Asked Questions
In most cases: 316 stainless + maintenance-free (PTFE-lined). Add 2RS if contamination ingress is likely (size dependent).
304 is fine for mild conditions; for salt spray, washdown, or chemical exposure, 316 is preferred.
Yes - maintenance-free (PTFE-lined) is our main offering. Lubricatable options are available upon request.
Not always. Availability depends on the bore size and series - please check the table or send an RFQ.
Yes. Share your part number/drawing or key dimensions, and we will recommend an equivalent.
