These deep groove ball bearings in the 6800Z–6807RS series are engineered for engineers, hobbyists, and repair technicians who need a dimensionally accurate, low-friction rolling element they can trust in tight spaces.\u003c\/p\u003e\n\u003cp\u003eEach bearing features a chrome steel (GCr15) inner and outer ring with a full complement of hardened steel balls. The Z-suffix variants use a single steel shield on one side for grease retention with lower drag; the RS-suffix variants use a contact rubber seal on both sides for superior dust and moisture exclusion. Inner diameters span 10–35 mm (0.39–1.38 in) and outer diameters span 19–47 mm (0.75–1.85 in), with widths of 5 mm or 7 mm depending on the model.\u003c\/p\u003e\n\u003cp\u003eTypical applications include RC car wheel hubs and motor shafts, inline skate and skateboard axles, small electric motors and fans, 3D printer carriage assemblies, and precision medical or lab equipment requiring low-noise rotation.

The shield retains grease and deflects larger particles but does not make contact with the inner ring, so friction is slightly lower — making Z bearings a good choice for higher-speed applications in relatively clean environments. The RS suffix indicates a rubber contact seal on both sides. The seal lip rides against the inner ring, providing a much tighter barrier against fine dust and light moisture, at the cost of marginally higher drag. Choose Z for speed-critical, clean applications; choose RS for dusty or lightly damp environments.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow do I select the correct bearing size for my application?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eMeasure your shaft diameter precisely with a caliper — this gives you the required inner diameter (ID). Then check the housing bore for the outer diameter (OD), and confirm the available axial space matches the bearing width (5 mm for 6800–6803, 7 mm for 6804–6807). Cross-reference these three dimensions with the variant selector on this page. If your shaft is metric and falls between standard sizes, do not force a bearing; contact us to confirm the closest fit.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eAre these bearings compatible with imperial (inch) shaft sizes?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eThese bearings are dimensioned in metric units following ISO 15 standards. While some metric IDs are close to common imperial fractions (e.g., 25 mm ≈ 0.984 in vs. 1 in), they are not interchangeable with true inch-bore bearings. Always verify the exact bore diameter of your shaft before ordering. If you are working with an inch-dimensioned shaft, contact us to confirm compatibility or to find an appropriate adapter sleeve.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDo I need to add grease before installing these bearings?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eNo. Each bearing arrives pre-greased with a general-purpose lithium-based grease suitable for most ambient-temperature applications. For high-temperature environments (above 120 °C \/ 248 °F), high-speed spindles, or food-grade applications, you may need to flush and repack with a specialty grease. In standard DIY, RC, or light industrial use, the factory grease is sufficient for the bearing's service life.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow corrosion-resistant are these bearings?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eGCr15 chrome steel offers good hardness and fatigue resistance but is not inherently stainless. The Z-shield variants have one open side that can allow moisture ingress over time. The RS-sealed variants provide better protection against light moisture and humidity. For applications involving water immersion, salt spray, or aggressive chemicals, consider stainless steel bearings (not this listing). For typical indoor or sheltered outdoor use, the RS variants with their rubber seals provide adequate corrosion protection when the seals remain intact.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan these bearings handle axial (thrust) loads in addition to radial loads?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eYes. Deep groove ball bearings are designed to handle both radial loads and moderate bidirectional axial (thrust) loads. They are not intended for applications where axial load is the dominant force — angular contact or thrust bearings are better suited for those cases. For typical DIY and light mechanical applications where axial forces are secondary to radial forces, these bearings perform reliably within their rated load envelope.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the maximum operating speed for these bearings?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eMaximum speed depends on the specific size, seal type, and lubrication. As a general guideline, smaller-bore Z-shield variants (e.g., 6800Z, 6801Z) can typically operate at 20,000–30,000 RPM under light loads with adequate lubrication, while larger RS-sealed variants run at lower maximum speeds due to seal friction.
