❓ Frequently Asked Questions
Q: What is the difference between flat straight-hole and flat arc-hole bearings?
A: The flat straight-hole bearing features a simple, straight inner hole ideal for general-purpose applications where stress concentration is not a primary concern. The arc-hole design is optimized for reducing stress at the hole edge, offering longer service life in high-frequency or high-load scenarios. The straight-hole is the most cost-effective option.
Q: Is this bearing suitable for high-speed applications?
A: Yes. With a friction coefficient of approximately 0.14 against steel and ultra-smooth surface finish, this bearing performs well in moderate to high-speed applications. For extreme high-speed operations, we recommend our groove-type or arc-hole designs.
Q: What is the coefficient of friction for this bearing?
A: The coefficient of friction against steel is approximately 0.14, ensuring smooth, low-friction operation.
Q: What are the standard dimensional ranges available?
A: Outer diameter Φ0.8–6.0mm, thickness 0.3–2.0mm, and inner hole Φ0.15–3.0mm. Custom dimensions are available upon request.
Q: Can you manufacture custom dimensions?
A: Yes. TAOMSUN supports custom outer diameters, thicknesses, and hole diameters. Please submit your CAD drawing or specifications for a tailored quote.
Q: What is the typical lead time for orders?
A: Standard stock items ship within 3–5 business days. Custom specifications typically require 2–4 weeks depending on complexity and volume.
