Frequently Asked Questions (FAQ)
Q1: Can this bearing support both axial and radial loads simultaneously?
Yes, the four-point contact ball design can handle axial, radial, and moment loads simultaneously. For higher moment stiffness, crossed roller configuration is recommended.
Q2: Is the 200mm OD exactly 200 mm or does it have tolerance?
The outer diameter is machined to nominal 200 mm with a standard tolerance of h6 (ISO) for P5 grade. Actual value will be within 0 to -0.029 mm.
Q3: What lubrication is recommended for robotic arm use?
We suggest a lithium-based grease with a wide temperature range (-30°C to +120°C). Optional oil lubrication can be designed with lubrication holes.
Q4: Can you provide a drawing or CAD model for integration?
Yes, we can provide 2D drawings and 3D models (STEP/IGES) after confirming the mounting interface dimensions. Please contact our sales team.
Q5: Do you offer samples before mass production?
Absolutely. Small quantity samples (1–5 pcs) are available for testing. Lead time is around 15–20 working days.
Q6: What is the minimum order quantity (MOQ)?
For standard designs, MOQ is 10 pcs. For fully customized bearings, MOQ can be discussed based on complexity.
Q7: How does your bearing compare to imported brands like INA or THK?
We provide equivalent precision and load ratings at a more competitive price. Our bearing is manufactured with modern CNC equipment and strict QC, ensuring reliable performance in most robotic applications.
Q8: What packaging and shipping methods do you use?
Each bearing is individually packed with anti-rust oil and wrapped in bubble film, then placed in a strong plywood case. We ship via sea or air from ports like Shanghai, Qingdao, Tianjin, and Lianyungang.
