FAQ:

Rod End Bearing SA...E / SA...ES / SA...ES-2RS FAQ

 
This FAQ covers model meaning, core differences, selection, installation, and maintenance for the most common rod end bearing series, fully aligned with international standards (SKF/ISB/GB/T 304) for procurement and after-sales communication.
 

 

1. What do the suffixes E, ES, and ES-2RS mean?

 

Q1: What is the complete model structure of SA series rod ends?

 
A: The standard model format is SA (Series Code) + Bore Size (mm) + Suffix (E/ES/ES-2RS).
 
  • SA: Male thread rod end (right-hand; left-hand is prefixed with L, e.g., SAL).
  • Suffix priority: -2RS (Sealing) > ES (Lubrication Feature) > E (Basic Structure). More suffixes = more comprehensive functions.
 

Q2: What are the key differences between SA...E, SA...ES, and SA...ES-2RS?

 
表格
 
 
 
Suffix Lubrication Design Sealing Type Key Features Best For
SA...E No grease fitting; small oil groove Open (no seal) Basic type; steel-on-steel sliding contact; requires periodic disassembly for relubrication Dry, clean, low-speed, low-load applications
SA...ES Grease fitting + internal/external oil grooves Open (no seal) Relubrication via fitting without disassembly; improved load capacity High-load, medium/high-speed machinery (e.g., hydraulic links)
SA...ES-2RS Grease fitting + oil grooves Double-lip NBR rubber seals Dust/waterproof; leak-proof; low maintenance Wet, dusty, outdoor, or harsh environments
 

Q3: How to interpret the numbers in the model (e.g., SA20 E, SA25 ES-2RS)?

 
A: The numbers directly indicate the inner diameter (mm).
 
  • Bore < 10mm: Exact size (e.g., SA8 E = 8mm bore).
  • Bore ≥ 500mm: Use "/" separator (e.g., SA/500 ES).
  • Optional suffixes: C = PTFE-coated bronze sliding surface (maintenance-free); can be combined with E/ES/ES-2RS (e.g., SA20 C ES-2RS).
 

 

2. Selection Guide: Which One to Choose?

 

Q4: What are the application scenarios for each type?

 
A: Choose based on environment + maintenance cost + load/speed:
 
  1. SA...E: Low-cost, basic type.
    • ✅ Dry, clean, low-speed (≤ 500 rpm), low-load equipment.
    • ❌ Requires relubrication every 1–3 months (disassembly needed).
     
  2. SA...ES: Relubrication-friendly type.
    • ✅ High-load, medium/high-speed (≤ 1500 rpm) machinery (e.g., machine tool links).
    • ✅ Relubricate via grease fitting every 6–12 months (no disassembly).
     
  3. SA...ES-2RS: Sealed & relubrication type.
    • ✅ Wet, dusty, outdoor, or corrosive environments (e.g., mining equipment).
    • ✅ Long maintenance cycle (1–2 years); waterproof splash (not full immersion).
     
 

Q5: Do SA...ES-2RS bearings prevent water ingress?

 
A: Yes, for water splash and dust, but not for continuous immersion.
 
  • Double lips create a tight seal against the inner ring to block water, dust, and contaminants.
  • For underwater or high-pressure spray conditions, add an additional waterproof cover.
 

Q6: Are there differences in load capacity between the three types?

 
A: At the same bore size, load capacity is nearly identical:
 
SA...ES-2RS ≈ SA...ES > SA...E
 
  • The ES/ES-2RS design optimizes lubrication grooves to reduce friction loss.
  • The ES-2RS seal does NOT affect radial/axial load transmission (axial load ≤ 20% of radial load).
 

 

3. Installation & Maintenance: Practical Guidelines

 

Q7: What are the critical installation rules?

 
A: Principle: Press-fit + Coaxial alignment. Avoid brute force:
 
  1. Press the outer ring into the housing using a press or sleeve (never hit the thread or inner ring).
  2. Ensure the rod end swings freely with no sticking.
  3. Preload: Leave a small clearance (0.1–0.3mm) to prevent overheating and seizing.
  4. Do NOT mix components from different bore sizes (e.g., SA20 outer ring + SA25 inner ring).
 

Q8: What grease should be used? What is the relubrication cycle?

 
A: Select grease based on temperature and environment:
 
  • General use: Lithium-based grease (-20°C ~ 120°C).
  • High temp (>120°C): Complex lithium grease.
  • Wet environment: Water-resistant lithium grease.
 
Relubrication cycle:
 
  • SA...E: Every 1–3 months.
  • SA...ES: Every 6–12 months (fill 1/3–1/2 of the bearing’s internal volume each time).
  • SA...ES-2RS: Every 1–2 years (drain old grease before adding new).
 

Q9: Can the ES-2RS seal be replaced? How?

 
A: Yes, seals are wear parts. Follow these steps:
 
  1. Gently pry out the old seal (avoid scratching the groove).
  2. Clean the groove of old grease and debris.
  3. Apply a thin layer of grease to the new seal (reduce friction).
  4. Press the new seal evenly into the groove (ensure lips are aligned and tight against the inner ring).
 
  • Note: Match seal material to 工况 (FKM for high temp, NBR for low temp).
 

 

4. Troubleshooting: Common Issues & Solutions

 

Q10: Bearing overheats (temperature > 80°C)?

 
A: Check 3 key factors (priority order):
 
  1. Over-preload: Too small internal clearance → disassemble and readjust.
  2. Grease issues: Overfilling (poor heat dissipation) → drain excess; wrong type → replace with matching grease.
  3. Seal friction (ES-2RS): Misaligned seal → check and replace with correct size.
 

Q11: Noise, sticking, or surface peeling?

 
A: Corresponding causes & fixes:
 
  • Noise/sticking: Lack of grease (SA...E: clean and relubricate; ES/ES-2RS: relubricate via fitting) or contamination (open-type E: severe cases need replacement).
  • Surface peeling: Overload (upgrade to larger bore/higher load rating) or installation damage (replace and 规范 installation).
 

Q12: Grease fitting is blocked. How to fix it?

 
A: Two-step solution:
 
  1. Mild blockage: Use a fine wire to unclog the channel; flush with a small amount of kerosene; then add grease.
  2. Severe blockage: Replace the grease fitting (use a matching size to avoid thread damage).
 

 

5. Business & Procurement FAQs

 

Q13: Are SA...E/ES/ES-2RS interchangeable with international brands (e.g., SKF)?

 
A: Yes, for standard sizes.
 
  • The SA series is designed to match international standards (GB/T 304 / ISO 12240-1).
  • For critical applications, confirm load rating, speed rating, and seal material to avoid mismatches.
 

Q14: What is the lead time for bulk orders?

 
A: Standard lead time: 15–30 days (stock items); custom sizes (e.g., special thread, non-standard bore) may take 30–60 days.
 
  • Urgent orders (≤ 7 days) are available for standard sizes with additional express fees.
 

Q15: Do you provide sample testing before bulk order?

 
A: Yes.
 
  • Free samples for standard sizes (shipping fee applies).
  • Third-party testing (e.g., dimensional accuracy, load test) is available upon request.
