type=\"application\/ld+json\">{\"@context\": \"https:\/\/schema.org\",\"@type\": \"FAQPage\",\"mainEntity\": [{\"@type\": \"Question\",\"name\": \"How does material purity influence the fatigue resistance of 6204 bearings?\",\"acceptedAnswer\": {\"@type\": \"Answer\",\"text\": \"Material purity is the primary determinant of the fatigue life cycle in the 6204. By using vacuum-degassed GCr15 steel, ZQM minimizes non-metallic inclusions that otherwise act as stress concentration points under the contact subsurface. If inclusions are present, the constant Hertzian contact stress will trigger subsurface cracks, leading to premature fatigue spalling. High purity ensures that the 6204 maintains its dimensional stability and load-carrying capacity over millions of stress cycles in industrial drives.\"}},{\"@type\": \"Question\",\"name\": \"What is the difference between CN and C3 clearance for a 6204 bearing?\",\"acceptedAnswer\": {\"@type\": \"Answer\",\"text\": \"CN (Normal) clearance is the standard internal gap for most general-purpose applications. C3 clearance provides a larger internal gap, which is necessary when the 6204 operates in high-temperature environments or when there is a heavy interference fit on the shaft. Choosing C3 ensures that internal clearance optimization is maintained even after thermal expansion, preventing the bearing from running too hot and suffering thermal seizure.\"}}]}<\/script><\/p>\n<h2>\u76f8\u5173\u8f74\u627f\u578b\u53f7<\/h2>\n<ul>\n<li>6203<\/li>\n<li>6205<\/li>\n<li>6004<\/li>\n<li>6304<\/li>\n<li>16204<\/li>\n<\/ul>\n<h2>\u6280\u672f\u652f\u6301\u4e0e\u56fd\u9645\u8be2\u4ef7<\/h2>\n<p>\u7fa4\u9a6c\u8f74\u627f\u4e3a\u8bbe\u5907\u5236\u9020\u5546\u3001\u7ecf\u9500\u5546\u53ca\u7ec8\u7aef\u91c7\u8d2d\u5546\u63d0\u4f9b\u8f74\u627f\u4f9b\u5e94\u4e0e\u51fa\u53e3\u6c9f\u901a\u3002\u8bf7\u63d0\u4f9b\u5b8c\u6574\u578b\u53f7\u3001\u6570\u91cf\u3001\u6536\u8d27\u76ee\u7684\u5730\u3001\u56fe\u7eb8\u53ca\u68c0\u9a8c\u8981\u6c42\uff0c\u786e\u8ba4\u6750\u6599\u3001\u4fdd\u6301\u67b6\u3001\u6e38\u9699\u3001\u5305\u88c5\u3001\u9632\u9508\u548c\u4ea4\u4ed8\u6761\u4ef6\u3002\u957f\u671f\u6279\u91cf\u8ba2\u5355\u53ef\u8fdb\u4e00\u6b65\u7ea6\u5b9a\u5c3a\u5bf8\u4e00\u81f4\u6027\u53ca\u8d28\u91cf\u6587\u4ef6\u8981\u6c42\uff1b\u670d\u52a1\u65f6\u95f4\u3001\u5e93\u5b58\u548c\u4ea4\u671f\u4ee5\u5b9e\u9645\u786e\u8ba4\u4e3a\u51c6\u3002<\/p>\n","protected":false},"excerpt":{"rendered":"<p><strong>\u7fa4\u9a6c\u8f74\u627f\uff08ZQM
