The increasing concerns about the health and safety is significantly changing the costeffective management of labor, also becoming an important tool in the pursuit of quality. In this context the present work makes a studyin a steel mill, to determine an action plan with the goal of reducing the risk of injury during handling and setting up bearings in a workshop of rolling mill rolls. The study is structured through the Method of Analysis and Troubleshooting, and quality tools. The definition of the action plan has brought lowcost measures that seek to solve the problem, eliminating the possibility of fatality or inability to employees

Have long studied the distribution of stresses in the cylinder. When this thickness is less than or equal to 10% of the inner radius is possible to consider a uniform distribution along the thickness of the tube. However, when the thickness is greater than 10% of the inner radius is necessary to consider the theory of thick-walled cylinders. This theory shows that when the thickness increases on the radius, the stresses do not act uniformly. The objective of this study is to determine the maximum stresses in thick-walled cylinders by comparing the results obtained by the theory of elasticity and the finite element method

[ES] En este trabajo se describe el desgaste adhesivo (scuffing) que representa la más severa de las agresiones a la que se ven expuestos aros de pistón y camisas de cilindro de motores diésel lentos de dos tiempos aplicados a la generación eléctrica, al quemar combustibles de bajo contenido en azufre. Al afectar simultáneamente, a estos dos elementos básicos de la cámara de combustión, repercute negativamente tanto en la continuidad del servicio del motor, como en los costes asociados a la restitución de las condiciones nominales de trabajo.
