Selecting the right grease for rolling bearings

When selecting a suitable grease for a rolling bearing a number of application-related factors need to be considered These include the type of bearing operating speed temperature and load Other factors such as mounting position sealing shock and vibration and legal/environmental regulations may also need to

What Lubricant to Select: Oil or Grease

The decision between selecting an oil or grease for lubrication can be made only after carefully considering several factors When to lubricate with oil: Oil is generally preferable in systems that consistently operate at high temperatures (over 200F) using oil is preferable over grease as one can install circulation systems to help cool the system units

Best RV Slide Lubricants

When selecting the right quantity make sure you consider the amount that would be needed in the lubrication process the frequency of the process and the amount needed to maintain the slide-outs condition Since most slide-out mechanisms require regular lubricant applications it's advisable to buy the product in bulk

Safe effective food and beverage seal technology

Many oil seals keep contaminants out when a pump or other equipment operates However when the machine is shut down moisture enters the bearing housing as the equipment moves toward equilibrium In some vertically oriented bearing isolators two static coalescing O-rings break down vapor and direct it into the expeller chamber (see Figure 1)

OIL SEAL: INSTALLATION TECHNIQUES AND PREVENTIVE

Oil seal is the physical barrier design to retain oil and pressure but excludes dirt moisture and contamination It is an integral part in any rotating and reciprocating system The purpose of oil seals is to provide sealing between the rotating crankshaft and the outside Oil seals consist of a metal housing
