Metric self aligning ball bearings are engineered for engineers, maintenance technicians, and equipment builders who need reliable rotation even when shaft and housing axes are not perfectly aligned — tolerating angular misalignment of typically 2°–3°.\u003c\/p\u003e\n\u003cp\u003eThis listing covers the full range of metric self aligning ball bearings from series 1018 through 2205, with bore diameters from 7 mm (0.28 in) to 50 mm (1.97 in), outer diameters from 22 mm (0.87 in) to 90 mm (3.54 in), and widths from 7 mm (0.28 in) to 23 mm (0.91 in). The inner ring features a spherical raceway that seats against the outer ring's concave spherical surface, allowing the self-aligning action without generating edge stress.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include conveyor drive shafts where frame flex causes continuous misalignment, agricultural equipment such as seeders and spreaders subject to vibration and debris, and light industrial gearboxes or fan assemblies where precise shaft alignment is difficult to maintain during field installation.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e⚙️\u003c\/span\u003e \u003cstrong\u003eCompatibility Note:\u003c\/strong\u003e These bearings follow ISO metric dimensional standards.

The 2xxx series (e.g., 2205, 2206) are double-row self aligning ball bearings with a wider body that carries higher radial loads and provides greater shaft support. For the same bore size, the 2xxx series will have a larger width (B) dimension.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow much angular misalignment can these bearings handle?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eMetric self aligning ball bearings typically tolerate angular misalignment of 2° to 3° between the shaft and housing axes. This is sufficient for most conveyor, agricultural, and light industrial applications where shaft deflection or imprecise mounting is expected. Exceeding this range will cause uneven ball loading and accelerated wear — if your application requires greater misalignment tolerance, consider spherical roller bearings instead.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eAre these bearings corrosion resistant for outdoor or wet environments?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eStandard metric self aligning ball bearings use carbon chromium steel rings and balls, which provide moderate corrosion resistance when properly lubricated and sealed.

Metric self aligning ball bearings follow ISO dimensional standards, so a 1205 bearing from any ISO-compliant source will share the same envelope dimensions: 25×52×15 mm. Always verify the three key dimensions rather than relying solely on the series number, as some manufacturers use non-standard suffixes that indicate modified dimensions.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat lubrication do these bearings require, and how often should I re-lubricate?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eOpen (unshielded) self aligning ball bearings require periodic grease replenishment — typically lithium-based NLGI #2 grease. Re-lubrication intervals depend on operating speed, temperature, and load, but a general guideline for moderate-duty applications is every 500–2,000 operating hours.
