    Common Procurement Mistakes Buyers Should Avoid

    1. Selecting Bearings Based Only on Price

    Low-cost bearings often result in higher maintenance costs and premature failures.

    2. Ignoring Bearing Lubrication

    Different applications require different grease or oil specifications.

    3. Overlooking Corrosion Resistance

    Saltwater fishing reels require stainless steel or ceramic bearing solutions.

    4. Focusing Only on ABEC Rating

    Bearing life also depends on material quality, raceway finish, and lubrication.

    5. Not Verifying Batch Consistency

    Always request inspection reports and material certifications before bulk orders.
