Lee Linear Reclassifies Tolerance Codes

Lee Linear, a manufacturer of linear motion components, has reclassified the tolerance codes for their case hardened linear shafting. The change was made to simplify the ordering process for customers. Customers can specify Lee's shafting by the different codes based upon the bearing use. Class S shafts accommodate "A" type linear ball bearings. Needle roller bearings should be used with Class N shafts. For die set bearings, customers should specify Class D shafting. Open and adjustable linear ball bearings and pillow blocks are best used with Class L shafting. International Standard Code (ISO 286-2) Precision Shafting can also be provided. "Lee remains committed to offering the finest quality linear components and customer service," said Alan Haveson, CEO of Lee Linear. "As new brochures and data sheets are printed, the new codes will be updated. The shafting codes on the company website are now being changed." Because specifying exact size increases manufacturing complexity and costs, correct tolerances are crucial for performance accuracy.
