It specifies the allowable deviation in diameter, roundness, and surface finish. Grade 200 is a general-purpose precision grade suitable for most replacement and DIY mechanical applications where tight tolerances are needed but ultra-precision grades (such as Grade 10 or Grade 25) are not required.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eAre these ball bearings suitable for outdoor or wet environments?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eYes. Stainless steel resists surface oxidation and corrosion in humid, wet, and mildly corrosive conditions. However, for prolonged immersion in saltwater or exposure to strong acids or chlorides, a higher-grade stainless alloy (such as 316 SS) may be more appropriate. If your application involves harsh chemical exposure, contact us to confirm suitability before ordering.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan I use these balls as replacements in a standard ball bearing race?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eYes, provided the diameter matches the race specification exactly. These are solid precision balls intended for use as rolling elements. Confirm the ball diameter called out in your bearing's datasheet or stamped on the race before selecting a size. Mixing ball sizes within a single race will cause uneven load distribution and accelerated wear.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the load capacity of these ball bearings?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eLoad capacity depends on the diameter, the material grade, and the specific application geometry (point contact vs. conforming race). As solid stainless steel spheres, larger diameters (50–60mm) support substantially higher compressive loads than smaller ones (30–35mm). For precise load ratings in a specific assembly, contact us to confirm — we can provide guidance based on your use case.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDo these ship individually or in sets?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eEach variant is sold as 1 piece (1 pcs) per order.
