1️⃣ **Unexpected downtime** – unprotected bearing ends expose the raceway to contaminants, causing up to 30 % more failures per year.
2️⃣ **High replacement cost** – a single bearing failure can cost $2,500–$5,000 in lost production and part replacement.
3️⃣ **Inconsistent quality from low‑priced suppliers** – variations in thickness or material lead to mis‑alignment and premature wear.
4️⃣ **Lengthy lead times** – generic stock items often arrive after the production schedule, forcing emergency orders.
🔎 Data point: 68 % of U.S. manufacturers report that bearing‑related failures are the top cause of unscheduled shutdowns.
