FAQ

Q: How does AstraRoll ensure the rollers can handle extremely heavy loads?

A: We use through-hardened steel shafts and oversized bearings. The entire structure is engineered for a higher loading capacity.

Q: Which surface treatment is best for outdoor/wet environments?

A: For superior rust protection, we recommend our high quality Zinc Galvanizing or Hard Chrome Plating. These treatments ensure long-term driving quiet wear resistance even when exposed to the elements.

Q: Can you provide custom shaft ends for specific mounting requirements?

A: Yes. Our steel idler rollers are fully customizable to interface seamlessly with various models of motors and mounting brackets, including hex-shafts, threaded ends, or custom keyways.

Q: Are these rollers suitable for high-speed conveyor systems?

A: Absolutely. By maintaining a TIR of ≤0.02mm and G1.0 balancing, we ensure vibration-free smooth moving and smooth driving at high linear speeds.
