What’s new shaft tolerance codes
Shaft tolerance codes are reclassified for customer convenience
In order to simplify the ordering process for its customers, Lee Linear has reclassified the tolerance codes for its case hardened linear shafting. Customers can specify the 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 shaft-easy-ing; and open and adjustable linear ball bearings and pillow blocks are best used with Class L shafting. ISO precision shafting also can be provided.

Apparel line offers maximum welder protection
Originally developed for military applications, Miller’s WeldX fabric combines the lightweight and breathability benefits of cotton with good spatter and flame resistance to protect welders from the hazards of heavy-duty welding. The fabric consists of a blend of oxidized acrylic fibres and strengthening fibres treated with a compound that allows the material to shed spatter and sparks. It is considerably lighter than most leathers, and also is lighter than many flame-resistant cotton garments. Laundering will not degrade its flame resistance over time. Garments made of this fabric are available as jackets, sleeves, cape sleeves, bibs and aprons to meet a variety of applications.
