FAQs About Needles for Bearings
- What is the difference between tapered needles and cylindrical needles? Tapered needles have a pointed end, while cylindrical needles have a flat end. Tapered needles provide higher load capacity in one direction, while cylindrical needles offer equal load capacity in both directions.
- What is the importance of surface finish? A high surface finish reduces friction and enhances bearing efficiency. Cold drawing or grinding processes are used to improve surface finishes.
- Can needles for bearings withstand high temperatures? Certain needles for bearings made from heat-resistant materials can tolerate temperatures up to 120°C (248°F).
