Precision Features a quality bearing design with speed bearings to deliver accuracy. This design reduces runout and helps achieve cleaner surface finishes during turning. Materials Conical part crafted from T10 steel with 5560 HRC. Main body made from 40Cr steel with 4550 HRC for enhanced durability and long service life. DustProof Seal Dustproof seal prevents cutting dust and chips from entering the bearings, helping to prolong bearing life and reduce maintenance. Balanced and Efficient Turning Wellbalanced and smooth operation provides stable support at the tailstock end of your lathe, enabling efficient and reliable turning. Use scenarios Supporting long, slender workpieces during turning to minimize deflection and improve accuracy. Precision turning of smalldiameter shafts where stable rotation and minimal vibration are important. Operations in dusty environments where cutting dust could affect bearings, with the dustproof seal helping to extend service life.
