Table of Contents

1. Product Overview & Specifications

The IKO PHS18A, PHS20A, and PHS22A rod end bearings are spherical plain bearings designed for heavy-duty applications. Key features include:

Model Inner Diameter (mm) Outer Diameter (mm) Load Capacity (kN) Seal Type
PHS18A 18 40 32 Advanced Oil Seal (AOS)[9]
PHS20A 20 45 45 Double Contact Seals[4]
PHS22A 22 50 58 Corrosion-Resistant Seal[9]

*All models use chromium steel (SUJ2)[4] with surface hardness HRC 58-62 for enhanced durability.

2. Key Applications & Industries

Primary industrial uses:

  • Construction Machinery: Excavator arm joints, crane rotation mechanisms
  • Agricultural Equipment: Combine harvester linkages, plow adjustments
  • Transportation: Truck suspension systems, trailer hitches

Optimized for applications requiring:

- Angular movement up to 15°
- High shock load resistance[3]
- Operation in contaminated environments[9]

3. Operational Best Practices

Installation guidelines:

  1. Clean mounting surfaces with non-abrasive solvents
  2. Use hydraulic press for interference fits >0.05mm
  3. Apply lithium-based grease (NLGI #2) during assembly

Maintenance cycle: Relubricate every 500 operating hours or 3 months in high-dust environments[4].

4. Real-World Use Cases

Case 1: Mining Conveyor System Upgrade
- Problem: Monthly bearing failures due to ore dust ingress
- Solution: PHS22A with triple-lip seals reduced downtime by 72%

Case 2: Bridge Construction Equipment
- Challenge: Saltwater corrosion in coastal projects
- Result: PHS20A's zinc-nickel coating extended service life to 18+ months

5. Client Success Stories

Client A: European Crane Manufacturer
- Application: 50-ton mobile crane slew bearings
- Outcome: 22% increase in mean time between failures (MTBF) using PHS18A

Client B: Asian Agricultural OEM
- Challenge: Mud contamination in rice planting equipment
- Solution: PHS22A implementation reduced maintenance costs by ¥1.2M annually
