  • Basics of Linear Bearings | Nippon Bearing

    Lubrication specialists can give recommendations for demanding applications but in general Thomson can advise: Light loads and high speeds do well with a machine oil or low viscosity grease. Medium loads and speeds do well with NLGI 1 or 2 grease. High loads may require a grease with an EP2 additive. The EP is Extreme Pressure and uses special ...

  • How often should I grease my bearings, and how

    A good way to accomplish this is to use a cylindrical roller bearing with one straight race at the “radial” location, as this bearing cannot take any thrust. A pair of angular contact bearings or steep angled tapered roller bearings is often a good choice to take the thrust load, but they must be prevented from seeing any radial load.

  • What should be used to lubricate linear bearings and

    Bushings and Plain Bearings - Load Capacity and Service Life. Several factors will influence the wear and service life of bushings. They are, among others, specific bearing load, sliding speed, PV value, surface roughness of mating parts, mating surface material, and operating temperature. The PV value has a considerable influence on the ...

  • Linear Bearings: Understanding the 2:1 Ratio and How

    2015-8-1 · When to use oil for linear bearings. Oil lubrication is recommended for high-speed applications, because it dissipates heat more readily than grease. It also flows and disperses better than grease. But when oil lubrication is used, the orientation of the bearing and the location of the lubrication ports must be taken into account.

  • Control Engineers Guide to Applying Linear Bearings

    2010-4-16 · Linear rolling element bearings are used in most critical industrial applications. They generate much less friction than sliding bearings so they can use a smaller motor and drive system and can run at considerably higher speeds. Linear rolling bearings also eliminate the stick-slip effect that often …

  • Mechanical Design Guidelines for Bearings

    Since linear bearings have become important primarily as a result of robotic automation, one must often refer to manufacturer's literature for load/life formulas. What follows is one way to calculate the life of a linear slide bearing. The symbol L is used to represent the rated life. It is defined as the length of travel endured by the slide ...

    2019-5-24 · For example, ball bearings can allow more time between regrease applications than those of most other bearing designs. Runtime – Running 24/7 versus sporadic use, or even how often there are starts and stops, will have an impact on how quickly the grease will degrade and how effectively the grease will stay in the key lubrication zones ...

  • Convolutional Neural Network Based Fault Detection

    2016-9-1 · Often, a bearing undergoes a combination of rolling and sliding. As a consequence, the calculated frequencies may differ slightly, i.e. 1–2 percent, compared to the actual frequencies [3] . Second, if multiple faults occur simultaneously, the frequencies generated can add and subtract, obfuscating important frequencies [2] .
