Precision 608ZZ & 608-2RS Bearings for Skateboards, Inline Skates & Scooters
We manufacture high-performance 608 miniature deep groove ball bearings (8x22x7mm) engineered specifically for skateboards, inline roller skates, scooters, and 3D printing equipment. Available in double metal shields (608ZZ) and dual rubber contact seals (608-2RS) with ABEC-7, ABEC-9, and ABEC-11 precision ratings. Built with chrome steel (GCr15) balls, nylon cages, and high-speed low-viscosity synthetic grease for ultra-smooth rotation and long service life. OEM laser branding, custom colored shields, and bulk tube or retail box packaging available.
608 bearings for skateboard and inline-skate wheel assemblies are available for replacement programs, wheel kits and OEM packing projects. This page is limited to the 608-format skate application so buyers can compare the closure, lubricant, packaging and inspection requirements without mixing in unrelated industrial bearing ranges.
The nominal 608 envelope is 8 mm bore × 22 mm outside diameter × 7 mm width. Treat this as a model reference: the ordered code, closure, internal clearance, lubricant, fit and acceptance criteria must be confirmed in the quotation, drawing or approved sample.
608 Bearings for Skateboard and Inline-Skate Replacement Programs
Skate brands, wheel assemblers, sporting-goods distributors and replacement-parts importers usually need more than the number “608.” Two bearings can share the same nominal dimensions while using different closures, grease, clearance or inspection requirements. Confirming those details before production helps reduce fit disputes and inconsistent repeat orders.


608ZZ vs 608-2RS: Select the Closure for the Application
| Option | Construction reference | Buyer should confirm |
|---|---|---|
| 608ZZ | Metal shields on both sides | Environment, lubricant, rotation/noise target and whether shielded construction matches the wheel program |
| 608-2RS | Contact-style rubber seals on both sides | Exposure to dust or moisture, starting resistance, lubricant and the approved sample standard |
Neither closure is automatically correct for every skate product. The choice should follow the wheel design, intended environment and buyer-approved performance check. If a particular precision grade is required, include the exact grade and inspection method in the RFQ instead of relying on a generic marketing label.
Specification Checklist for a Repeatable 608 Bearing Order
| RFQ item | Reference or decision | How it is controlled |
|---|---|---|
| Bearing code | 608ZZ or 608-2RS | Quotation and sample marking |
| Nominal size | 8 × 22 × 7 mm | Drawing, gauge plan or buyer-approved sample |
| Material and clearance | State the required ring/ball material and clearance if controlled | Supplier offer and inspection documents for the ordered configuration |
| Lubrication | Operating temperature, storage, rotation feel and noise expectation | Approved lubricant and sealed sample |
| Wheel fit | Hub bore, spacer/axle arrangement and assembly method | Wheel drawing or assembled sample review |
| Packaging | Bulk, tube, individual or retail-set discussion | Confirmed pack count, label, barcode and carton mark |
| Order plan | Sample quantity, trial order and forecast | Written approval before volume production |
Commercial Value for Importers, Skate Brands and Wheel Assemblers
- Clear replacement positioning: keep one 608-format program focused on skateboard and inline-skate wheel assemblies rather than mixing unrelated bearing sizes and industrial uses.
- Fewer avoidable mismatches: agree the closure, lubricant, wheel fit and packaging before the trial order.
- Private-label readiness: discuss set quantity, label artwork, barcode and carton marking for distributor or brand programs.
- Repeat-order control: retain the approved sample and written specification so later batches can be checked against the same requirements.
This purchasing structure is designed to protect sell-through and after-sales margin by reducing preventable specification errors. It does not replace application validation: final suitability belongs to the buyer’s wheel assembly and approval process.
Frequently Asked Questions
Are all 608 bearings interchangeable?
The 608 code normally identifies the same nominal 8 × 22 × 7 mm envelope, but closure, clearance, lubricant, tolerances and running characteristics can differ. Confirm the complete requirement before replacing an approved bearing.
Should a skate buyer choose 608ZZ or 608-2RS?
Choose from the actual wheel design and operating environment. Tell us whether the current bearing uses metal shields or rubber seals and provide the expected rotation/noise check so the quotation can match the intended program.
Can bearings be packed as replacement sets?
Set packing, labels, barcodes and private-label cartons can be reviewed for B2B orders. Send the required pieces per set, artwork status, destination market and quantity; the final pack format is confirmed in the quotation.
What information speeds up an OEM quotation?
Send the bearing code, closure, wheel or assembly photo, measured dimensions, operating environment, packaging, destination market and order quantity. A sample or drawing is recommended when replacing an existing component.
Request a 608 Skate Bearing Quote
Send your current bearing marking, wheel application, closure preference, packaging and estimated quantity. We will review the specification before quoting the applicable configuration.
