When it comes to shaping and machining steel, precision is everything. A drill bit labeled “5mm” must always measure 5mm, no matter who manufactured it. This is where DIN standards (Deutsches Institut für Normung) come into play. Established in Germany, DIN ensures that tools and components are consistent, reliable, and interchangeable.
Many rotating shafts in mining and industrial equipment run on journal bearings also known as plain bearings. Unlike ball bearings, which use rolling elements, journal bearings rely on sliding contact between the shaft and bearing surface.They are strong, simple, and cost-effective, but they face two constant challenges: friction and wear.
