It is a setscrew-type shaft collar for applications supporting low axial loads and simple positioning. Setscrew collars have improved holding power when the shaft material is softer than the setscrew material. It is made of nylon for high strength, flexibility, and increased resistance to abrasion, crushing, and cracking.

If strength considerations turn out to dominate over deflection, then a higher strength material should be tried, allowing the shaft sizes to be reduced until excess deflection becomes an issue. The cost of the material and its processing must be weighed against the need for smaller shaft diameters.

The crushing action occurs when the moveable jaw is rocked against its fixed counterpart as the eccentric shaft at the top of the chamber rotates. An added benefit of jaw crushers is the reversible hydrostatic drive which makes for easy blockage clearing and easy maintenance. Jaw crushers are known for low fuel consumption comparative

Strength. The strength of a drilled shaft concrete is typically specified by its 28-day compressive strength, as tested on 6-inch diameter by 12-inch high cylinders. A mixture for a filled shaft will be adequate if it produces 28-day compressive cylinder strengths between 3,500 to 4,000 psi.

I suspect all of those modern materials are too something, e.g., too brittle, too flexible, too stiff. In the case of graphite or carbon fiber, it''d be a hollow tube of spear shaft diameter, so that might be subject to crushing, warping, collapsing, shattering? And would a spear shaft length of polypropylene be too dense and heavy?

Similar to structures under tension or compression, two important mechanical properties of shafts under torque loads are shear stress and shear strain. Stress is a material’s resistance to an applied force, and strain is the deformation that results from stress. Shear stress and shear strain (which are caused by torsional loads) occur when a

Linear Motion Shafts with Machinable Ends. With 2" of each end softened, it''s easier to machine a custom end for mounting. The rest of the shaft is case- hardened, which increases hardness and wear resistance on the surface of the shaft while allowing the center to remain soft for absorbing stresses caused by shifting loads.
