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?

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
Press the outer ring into the housing using a press or sleeve (never hit the thread or inner ring).
Ensure the rod end swings freely with no sticking.
Preload: Leave a small clearance (0.1–0.3mm) to prevent overheating and seizing.
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:
Gently pry out the old seal (avoid scratching the groove).
Clean the groove of old grease and debris.
Apply a thin layer of grease to the new seal (reduce friction).
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):
Over-preload: Too small internal clearance → disassemble and readjust.
Grease issues: Overfilling (poor heat dissipation) → drain excess; wrong type → replace with matching grease.
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:
Mild blockage: Use a fine wire to unclog the channel; flush with a small amount of kerosene; then add grease.
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.
