Import 608zz Skateboard Bearing — Buy in wholesale FOB from Supplier in China

The 608ZZ skateboard bearing is a standard deep groove ball bearing with two metal shields (ZZ designation) that seal against dust ingress while retaining factory lubrication. Shenzhen Ferris Trading Co., Ltd. offers this bearing in precision grades from P0 through P4, with material options spanning bearing steel (GCr15), stainless steel 440C, and ceramic silicon nitride. The 8 mm inner diameter, 22 mm outer diameter, and 7 mm width conform to the ISO 608 dimension standard, making this bearing interchangeable across skateboard, inline skate, and roller skate assemblies worldwide.

Bearing steel GCr15 represents the standard grade for general skateboard applications, offering a hardness of 60-65 HRC and typical fatigue life suited to recreational impact loads. Stainless steel 440C provides enhanced corrosion resistance for humid or coastal environments, though at a trade-off in cost and slightly lower hardness than GCr15. Ceramic silicon nitride variants reduce centrifugal force at high rotational speeds due to lower density, run with reduced lubrication requirements, and resist thermal expansion; these properties suit performance longboard and downhill skate builds where sustained speed matters. The double metal shield (ZZ) configuration does not seal as hermetically as rubber contact seals (2RS), but permits lower friction and is standard for skate applications where periodic maintenance is acceptable.

B2B buyers for this product include skateboard and action-sports equipment manufacturers, scooter and caster wheel producers, and industrial conveyor and automation OEMs who leverage the 608 form factor. The bearing's ABEC rating and precision grade should be matched to the intended RPM and runout tolerance of the end application; P0 suffices for most skateboards, while P5 or P4 suit motorized or precision industrial uses. Buyers should confirm with Shenzhen Ferris Trading Co., Ltd. whether the quoted precision grade refers to Chinese GB/T 307.1 standards or ISO 492, as grade nomenclature and tolerance bands differ between national systems. Bulk orders typically require clarification of lubricant type (lithium grease, oil, or dry film), shield material (pressed steel or stainless), and whether the supplier performs 100% noise or vibration testing before shipment.

Shenzhen Ferris Trading Co., Ltd. is located at Block 1, Oriental Pearl City in Shenzhen's Longgang District, a major electronics and component manufacturing hub in southern China. The company holds a harbor trust tier on the platform, and its response rate is currently recorded at 0.00% with zero average response hours, which indicates that direct communication may be delayed or unmonitored. Buyers should factor this into their sourcing timeline and consider initiating contact well ahead of planned purchase dates.

The supplier's profile does not disclose factory ownership, production floor details, or in-house quality accreditation. The listing presents the 608ZZ bearing across a broad material and precision spectrum (bearing steel through ceramic, P0 through P4), which suggests trading or distributorship rather than captive manufacture. No stated headcount, revenue figure, or client references appear in the available data. Buyers are advised to request the supplier's business licence scope, any ISO 9001 or manufacturing-specific certificates, and details of their upstream factory relationships before committing to volume orders.
