Frequently Asked Questions

608ZZ buyer questions, answered.

What is the difference between 608ZZ and 608-2RS?

608ZZ uses metal shields on both sides -- best for high-speed and clean environments. 608-2RS uses rubber contact seals -- better for dusty or humid environments but with slightly lower max speed.

What is the minimum order quantity (MOQ)?

Standard MOQ is 100 pieces for trial orders. Volume tiers start at 1,000 / 10,000 / 100,000 pieces with progressively better pricing. Contact us on WhatsApp for current pricing tiers.

What is the typical lead time?

Standard 608ZZ orders ship in 7 days from stock. Custom-spec orders (special clearance, lubricant, or noise grade) typically ship in 2-4 weeks.

Which noise grades and tolerance classes are available?

Noise grades Z1V1, Z2V2, and Z3V3 are stocked. Tolerance classes ABEC-1, ABEC-3, ABEC-5, and ABEC-7 are available. Higher grades are recommended for drones, robotics, and premium home appliances.

Do you provide samples before bulk orders?

Yes. Paid samples are available for any quantity. Free samples are provided for confirmed projects with order intent above USD 50,000. Buyers cover express shipping costs.

What shipping methods do you support?

Express (DHL/FedEx/UPS) for sample and small orders, air freight for medium orders, and FCL/LCL sea freight for bulk shipments. We deliver to 50+ countries with full export documentation.
