I tend to use Oilite as a generic term for sintered bronze. It seems to be a common usage among older mechanics and machinists... Oilite kind of rolls off the tongue better than sintered bronze. I am pretty sure that Oilite didn't invent sintered bronze, but rather were the first to market oil infused sintered bronze, and claim it was a lifetime lubricated bearing... it most certainly isn't... unless you gauge lifetime to be the devices working life. I am certain that you are right, Oilite is a pre-oiled product, and in light duty, slow speed applications it is used that way quite often... A turntable fits that description. However, in higher speed, heavier duty applications it is all but unheard of to use it that way. Things like blowers that need to be quieter than ball bearing will allow, furnace blowers, bathroom ventilation fans, ... Tektronix 500 series scope fans... In these sorts of applications, an oil reservoir is used. It may be only filled by the motor's manufacturer, but it is a reservoir none the less. Turbine oil has a slightly more noble purpose, being intended for pressurized lubrication systems in jet engines... but that is exactly the same sort of bearing as is serviced by automotive motor oil. Turbocharged engines have turbines that spin faster than 100KRPM, and use a synthetic motor oil, such as mobil 1. Turbine oil, and light weight motor oil work equally well for these lowly light duty motors. I have both on my bench, and which I use is more dependent on which container will fit the motor I am oiling. My 5W30 synthetic motor oil has a 16ga blunt needle, and the turbine oil has a 6" long 3/16" wide straw... ...Very scientific!... -Chuck Harris Richard Knoppow wrote: Look at the Oilite web site. They state that the oil is infused via vacuum. This |
