If load capacity is the priority, choose 440; if corrosion resistance in aggressive media is the priority, choose 304.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow do I select the correct bore size for my shaft?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eMatch the bearing bore diameter to your shaft diameter. The S1200–S1209 series covers bore sizes from 10 mm to 45 mm in standard increments. For a proper fit, the shaft should fall within the bearing's recommended tolerance band (typically h6 or js6 for rotating inner ring applications). Measure your shaft with a micrometer and select the corresponding S-series designation: for example, a 20 mm shaft takes an S1204 (20×47×14 mm).\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eCan these bearings handle misalignment, and how much?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eYes. The spherical plain design allows the inner ring to tilt relative to the outer ring, compensating for angular misalignment. The typical self-aligning range for this bearing type is ±2° to ±4° depending on the specific size and load conditions. This makes them suitable for pivot points, linkage assemblies, and installations where shaft deflection or housing misalignment cannot be fully eliminated during assembly.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eAre these bearings suitable for food processing or washdown environments?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eStainless steel construction makes these bearings significantly more resistant to moisture and mild cleaning agents than carbon steel alternatives. For food processing applications, the 304 stainless steel variant is generally preferred due to its better resistance to the acidic and chloride-containing cleaning solutions commonly used in food plants. Always verify that the lubrication used is food-grade if direct or incidental food contact is possible.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat housing type is compatible with the S1200–S1209 series?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eThese bearings are designed to fit standard spherical plain bearing housings and pillow block units that accept the corresponding outer diameter. For example, the S1204 (20×47×14 mm) fits housings bored to 47 mm with the appropriate tolerance. Always confirm the housing bore diameter, width, and any snap ring groove requirements against the specific bearing dimensions listed in the variant options before ordering.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow should I lubricate and maintain these bearings?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eSpherical plain ball bearings in this series are typically supplied without pre-packed grease unless otherwise specified. Apply a suitable grease (lithium-based or synthetic, depending on operating temperature and environment) during installation. In wet or washdown environments, use a water-resistant grease and establish a relubrication interval based on operating hours and conditions. Inspect periodically for wear on the spherical contact surfaces, as these bearings do not have rolling elements and rely on sliding contact between the inner and outer rings.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow do I know if I need a spherical plain bearing instead of a standard deep groove ball bearing?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eChoose a spherical plain bearing when your application involves oscillating or slow rotational movement, angular misalignment between shaft and housing, or combined radial and axial loads in a compact envelope. Standard deep groove ball bearings are optimized for continuous rotation with minimal misalignment. If your shaft deflects, pivots, or rocks rather than spinning continuously at speed, a spherical plain bearing is the more appropriate selection.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-cta\"\u003e🛒 Select your Size and Material above, then add to cart.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"HomeDIYer","offers":[{"title":"S1200 (10x30x9mm) \/ 440 Stainless Steel \/ 1 pcs","offer_id":52410006339858,"sku":"XFSKDLJX0885x1","price":14.01,"currency_code":"USD","in_stock":true},{"title":"S1201 (13x32x10mm) \/ 440 Stainless Steel \/ 1 pcs","offer_id":52410006372626,"sku":"XFSKDLJX0886x1","price":15.91,"currency_code":"USD","in_stock":true},{"title":"S1202 (15x35x11mm) \/ 440 Stainless Steel \/ 1 pcs","offer_id":52410006405394,"sku":"XFSKDLJX0887x1","price":18.09,"currency_code":"USD","in_stock":true},{"title":"S1203 (17x40x12mm) \/ 440 Stainless Steel \/ 1 pcs","offer_id":52410006438162,"sku":"XFSKDLJX0888x1","price":22.82,"currency_code":"USD","in_stock":true},{"title":"S1204 (20x47x14mm) \/ 440 Stainless Steel \/ 1 pcs","offer_id":52410006470930,"sku":"XFSKDLJX0889x1","price":24.72,"currency_code":"USD","in_stock":true},{"title":"S1205 (25x52x15mm) \/ 440 Stainless Steel \/ 1 pcs","offer_id":52410006503698,"sku":"XFSKDLJX0890x1","price":27.88,"currency_code":"USD","in_stock":true},{"title":"S1206 (30x62x16mm) \/ 440 Stainless Steel \/ 1 pcs","offer_id":52410006536466,"sku":"XFSKDLJX0891x1","price":36.69,"currency_code":"USD","in_stock":true},{"title":"S1207 (35x72x17mm) \/ 440 Stainless Steel \/ 1 pcs","offer_id":52410006569234,"sku":"XFSKDLJX0892x1","price":52.9,"currency_code":"USD","in_stock":true},{"title":"S1208 (40x80x18mm) \/ 440 Stainless Steel \/ 1 pcs","offer_id":52410006602002,"sku":"XFSKDLJX0893x1","price":67.59,"currency_code":"USD","in_stock":true},{"title":"S1209 (45x85x19mm) \/ 440 Stainless Steel \/ 1 pcs","offer_id":52410006634770,"sku":"XFSKDLJX0894x1","price":85.11,"currency_code":"USD","in_stock":true},{"title":"S1202 (15x35x11mm) \/ 304 Stainless Steel \/ 1 pcs","offer_id":52410006667538,"sku":"XFSKDLJX0898x1","price":34.24,"currency_code":"USD","in_stock":true},{"title":"S1204 (20x47x14mm) \/ 304 Stainless Steel \/ 1 pcs","offer_id":52410006700306,"sku":"XFSKDLJX0900x1","price":29.62,"currency_code":"USD","in_stock":true},{"title":"S1205 (25x52x15mm) \/ 304 Stainless Steel \/ 1 pcs","offer_id":52410006733074,"sku":"XFSKDLJX0901x1","price":39.03,"currency_code":"USD","in_stock":true},{"title":"S1206 (30x62x16mm) \/ 304 Stainless Steel \/ 1 pcs","offer_id":52410006765842,"sku":"XFSKDLJX0902x1","price":48.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0884\/8936\/1682\/files\/Main-06_0c63de50-e95a-4f1f-b837-ec3305dde555.jpg?v=1782359683","url":"https:\/\/homediyer.com\/products\/stainless-steel-spherical-plain-ball-bearings-s1200-s1209","provider":"HomeDIYer","version":"1.0","type":"link"}
