It retains the standard 608 dimensions of 8 mm bore, 22 mm outer diameter and 7 mm width, while the B16 variant expands the inner width to 16 mm, giving an overall size of 8 × 22 × 16 mm. The bearing is forged from Chrome Steel GCr15 (AISI 52100), a high‑carbon alloy known for hardness and wear resistance. The ZZ designation indicates a pair of metal shields on both sides to protect against contaminants.
GCr15 steel conforms to ISO 281 standards for bearing steel, delivering a typical Brinell hardness of 650 HB. The extended inner race reduces material usage and cost, a practice common in caster wheel assemblies where axial load is minimal. Dimensional tolerances for the 608 series follow the CN tolerance class, providing a radial runout within ±5 µm. Typical operating speed for this size bearing reaches up to 20 000 rpm when properly lubricated.
These bearings are widely used in office furniture casters, industrial trolleys and medium‑load machinery where compact size and reliable rotation are required. Importers usually request bulk packaging of 100 units per bag and may negotiate custom packaging for larger orders. Because the listing does not disclose minimum order quantity, lead time or payment terms, buyers should confirm those details directly with the supplier before placing an order.

Before placing an order, importers should request a material test report confirming the GCr15 composition and hardness, as well as a dimensional inspection certificate that verifies the 8 × 22 × 16 mm size of the extended inner version. Verifying the supplier’s business licence and matching the listed address with local registries adds confidence in the source.
Logistics for these bearings are typically arranged under FOB or CIF terms, but the exact Incoterm and payment schedule must be agreed with Ningbo Hongtai Bearing Co., Ltd. Lead times are not stated in the listing, so buyers should ask for production lead time and any capacity constraints, especially for orders exceeding the standard 100‑unit bag size.
Quality control generally includes visual inspection for surface defects, dimensional checks, and a run‑out test at rated speed. Requesting a third‑party inspection report or arranging an on‑site audit can further assure compliance. Documentation such as a mill test report and a conformity declaration should be obtained prior to shipment.
