While shafts may appear the same to the untrained eye on the surface, there are significant performance differences due to the manufacturer’s selected standards and the manufacturing processes used to achieve them. Thomson 60 Case was developed and is continually enhanced because of our goal to provide a consistent finish, roundness, straightness, cylindricity case hardness and depth on all shafting for the demands of a linear bearing. Unlike common shafting, Thomson 60 Case shafting is manufactured to the highest quality standards in an ISO 9000:2000 registered facility. Our techniques have been continuously upgraded with proprietary knowledge gained from over 50 years of manufacturing experience. Using Thomson 60 Case with Thomson Ball Bushing bearings ensures optimal bearing performance and travel life. Assortment Thomson 60 Case is available from stock in Carbon Steel, 440 C Stainless Steel, 52100 Tubular, 316 Stainless Steel, Carbon Steel Chrome Plated, Carbon Steel Predrilled, and 440 C Stainless Predrilled from 3/16 to 4”. Thomson 60 Case can be mounted or delivered pre-assembled, in three configurations: type SR standard support rails, type LSR low profile support rails and type XSR extra rigid support rails. Contact Danaher Motion or review the catalog datasheets to see available diameters for the different materials. Danaher Motion has the widest range of materials and diameters available on the market from one source. Material Thomson 60 Case carbon steel shafting is made of high quality specially developed alloy steel. When it comes to linear shafting no other manufacturers have set such high standards or specifications for the raw steel used in the production of linear shafting. The chemical properties of the steel are customized to provide consistent, homogenous microstructure and proper response to thermal processing. When you use Thomson 60 Case you can be confident you get consistent material from shaft to shaft. Case Hardness All Thomson 60 Case is induction hardened and the hardness varies by material type. Thomson 60 Case carbon steel shaft is induction hardened to a 60 Rc min. The Thomson 440C “corrosion resistant” stainless steel shafting is hardened to a 50 Rc min. The 316 Thomson “corrosion proof” stainless steel is not hardened. The Thomson 52100 Tubular shafting is hardened to a 58 Rc min. Case Depth The case depth on all Thomson 60 Case Shafting is precisely controlled for consistent quality and optimal performance. The extremely hard surface minimizes wear when acting as an inner race of a linear bearing, is resistant to seal lip wear, nicks and scratches for your application needs. The Thomson 60 Case standard case depth is, in some cases, double competitor shafting. This deeper standard case depth provides a stronger, more consistent homogenous microstructure for a linear bearing to run on leading to an increase in shaft life. For special applications Danaher Motion offers deep case in carbon steel, where the case depth is two times the normal depth. For specific case depths refer to catalog datasheets.
