Minimum hardness for roller bearing shafting?

May 28, 2009The reason for hardness is the line loads applied. 60+ Rc will hold up lots longer than 35 Rc before one of those rollers sinks into the steel. You don't say how long the bearing is, but lets say the the 2500 lbs is sitting on one roller and the area of the roller Get price

Surface Additives – BYK

If, for example, the surface tension of the coating is higher than that of the substrate, this manifests itself in poor wetting (high contact angle) and, with that poor adhesion and cratering. Also after the application and while the coating is drying, local surface tension differences can cause unfavorable leveling and the floating of pigments. Get price

Controlling product quality with hardness testing

Aug 30, 2018The Brinell hardness number, or simply the Brinell number, is obtained by dividing the load used, in kilograms, by the actual surface area of the indentation, in square millimetres. In the Vickers test the surface is subjected to a pre-defined load exerted by a four-sided pyramidal diamond indenter for a standardised length of time referred to Get price

Do you have information about water hardness in the United

View a national map of hardness in surface water on the USGS water hardness website. Hardness data (reflecting mostly calcium, plus a little magnesium) for individual drinking-water suppliers is at the EPA Office of Ground Water and Drinking Water website. It is important to note that the U.S. Environmental Protection Agency (EPA) has not set a legal limit or standard for hardness in water. Get price

Case (Surface) Hardening versus Through Hardening of Steel

Notably, the carbon source can be gas, liquid, or solid. Finally, after quenching, a hard surface layer, known as a "case", will form. The most common depth is in the range 0.020"-0.030". Importantly, the process results in increased hardness on the outside of the material; however, the low carbon core remains relatively soft. Get price

Everything You Need to Identify Rocks

Feb 24, 2020Grain Size: Coarse grains are visible to the naked eye, and the minerals can usually be identified without using a magnifier. Fine grains are smaller and usually cannot be identified without using a magnifier.; Hardness: This is measured with the Mohs scale and refers to the minerals contained within a rock. In simple terms, hard rock scratches glass and steel, usually signifying the minerals Get price

How to measure the concrete hardness

To measure the hardness of something you need a scale and instruments that allow it. The first scale was devised by German geologist Friedrich Mohs.. Mohs worked on cataloguing and developing a scale to evaluate the hardness of various minerals. In this way, he was able to determine that diamond is the hardest material. Get price

Surface hardness

The surface hardness is given as Rockwell hardness HRC. If the surface hardness is smaller than 58 HRC, a reduction in dynamic and static load capacity is taken into account according (Harris, et al., 2009). This reduction is only considered as long as the load capacity is calculated by the software. The reduction factor for dynamic load Get price

Gear Materials

This treatment is usually performed on the surface for partial hardening of iron and steel.
