-
Forging Machines (hot forming) - (32 companies)Forging machines (hot forming) use compressive force and a high workpiece temperature to shape metal by plastic deformation. A type of hot forming, hot forging involves the plastic deformation of a metal at a temperature and strain rate where recrystallization and deformation occur simultaneously. This prevents strain hardening, which can reduce ductility and contribute to brittle failure and structural fatigue. -
Milling Machines - (672 companies)Milling machines move a clamped workpiece into a fixed, rotating cutter; or move the cutter itself into a stationary workpiece. There are two basic configurations: vertical and horizontal. Milling machines move a workpiece into a fixed cutter...

Inductotherm Group
Inductotherm Rail & Mill Roll Hardening Mill Roll & Rail Hardening Systems: The expanding development of cold mills, in which the rolls are subjected to high stresses, is being pursued in parallel with research to obtain rolls with high strength and resistance to surface wear. Induction heating has greatly contributed to improvements in hardening depth, with subsequent improvement in distribution of residual stresses. This has increased roll life and reduced the number of retreatments that rolls must undergo before completely wearing (read more)Browse Induction Heaters Datasheets for Inductotherm Group -

NB Corporation of America
Get Rolling with Crossed Roller Bearings! Crossed roller bearings provide more accuracy, rigidity, and weight-bearing capacity for linear motion than other commonly used friction-reducing devices such as ball bearings. And unlike ball bearings, they can support moment loads, radial forces or tilting loads. This lets one crossed roller bearing replace more than one ball bearing, thus saving the space required by ball bearings, lowering the associated material costs. Crossed roller bearings are preferred for high-precision linear-motion... (read more)Browse Crossed Roller Slides Datasheets for NB Corporation of America -

Waukesha Bearings
Fluid Film Bearings vs. Rolling Element Bearings Relative Motion. A bearing allows relative motion between two surfaces with minimal friction. In a rolling element bearing, the primary motion is a rolling motion using a ball or roller. There is direct contact between the ball/roller and the inner and outer surfaces (races). In a fluid film bearing, the relative motion between the two surfaces is a sliding motion on a shear of film (the lubricant). There is no contact of the surfaces except during start-up or shutdown.

National Bolt & Nut Corporation
Premium Cotter Pins from National Bolt & Nut Corp. COTTER PINS. Cotter pins, also called split pins, are equipped with two tines that bend during application. These metal fasteners lock in place during installation when the two ends of the cotter pin are bent apart, and are meant for temporary use. At National Bolt & Nut, we offer a line of premium cotter pins that feature an extended prong style. This prong style makes it easier to separate the tines during application. All of our premium cotter pins meet ANSI B18.8.1 dimensional... (read more)Browse Cotter Pins and Wire Clips Datasheets for National Bolt & Nut Corporation -
