I'm interested in sourcing sealed-bearing TCI options in both 6-inch and 8-inch sizes. Could you provide details regarding your availability and pricing for these products? It's essential for me to know about the specifications, including material quality and any certifications that your products might have. Additionally, I'd appreciate information about your lead times for order fulfillment and whether you offer bulk purchasing discounts.
