Frequently asked questions
Yes. Manufacturers can work to your drawing, datasheet or a reference sample, including bore, length, liner material and housing. Send the drawing with your quote request and suppliers will confirm what they can match.
Send the shaft diameter and tolerance, bush length and outer diameter, material, lubrication method, load, speed, temperature and quantity.
Plain bushes are quieter, handle dirt and shock better and need little lubrication, while ball bushes give lower friction and higher precision. Describe your load and speed so suppliers can advise.
Lead time depends on the specification, material, housing and quantity. Every quotation states its own lead time.
