1. Sky‑rocketing Prices – Global shortages push unit costs above $12 per sleeve, eroding margins.
2. Inconsistent Dimensions – Tolerances outside ±0.05 mm cause assembly re‑work and downtime.
3. Poor Surface Finish – Rough finishes increase wear on bearings, leading to 15‑20% higher maintenance.
4. Lengthy Lead Times – Typical suppliers need 4‑6 weeks, delaying production schedules.
5. Limited Customization – One‑size‑fits‑all designs restrict engineering flexibility.
