What is Shore Hardness?
Hardness, in basic terms, is the resistance of a material against intrusion and permanent deformation by a harder body. It is one property that is important for the proper specification and function of seals and other critical components in fluid power systems. Hardness of seal materials like rubbers, elastomers and plastics are typically … [Read more...] about What is Shore Hardness?
What is the Varnish Potential Rating?
Problems that crop up in hydraulic systems are often caused by contaminants like dirt and water in the oil that lead to corrosion, wear and premature failure. But many performance problems are due to another contaminant: varnish that coats control valves, restricts filters, and fouls reservoirs and other internal parts. Most hydraulics users are … [Read more...] about What is the Varnish Potential Rating?
