In many cases, the root cause is incorrect bearing selection.<\/p><p data-start=\"1628\" data-end=\"1762\">Choosing a bearing only based on size, price, or previous experience may lead to nexpected overheating\u3001Excessive vibration\u3001Short service life\u3001Frequent maintenance\u3001Unexpected equipment downtime<\/p><p data-start=\"1971\" data-end=\"2135\">A suitable bearing must match the
