Also, a radiological procedure is available as a reliable and accurate test for SS. A contrast agent is injected into the parotid duct, which opens from the cheek into the vestibule of the mouth opposite the neck of the upper second molar tooth . Histopathology studies should show focal lymphocytic sialadenitis . Objective evidence of salivary gland involvement is tested through ultrasound examinations, the level of unstimulated whole salivary flow, a parotid sialography or salivary scintigraphy , and autoantibodies against Ro (SSA) and/or La (SSB) antigens.

Greg Locock RE: lubricating plastic gears CoryPad (Materials) 21 Jul 02 21:43 fluorocarbons like Teflon are compounded into polymers (frequently for gear applications), not coated onto them.  I have no experience with separately applied lubricant. RE: lubricating plastic gears Biggadike (Mechanical) 22 Jul 02 02:58 We regularly find we have to lubricate plastic gears.
You can try Molycote PG75 which is a silicon based grease designed for just that purpose. Normal greases cause problems on plastic parts. RE: lubricating plastic gears cgrace12 (Mechanical) 22 Jul 02 09:12 We found white lithium grease to be useful... but you will want to test it, it may compound the problem.  Are the gears wearing at the teeth or the bearing?

RE: lubricating plastic gears 2 TVP (Materials) 22 Jul 02 12:01 Lubricants are frequently used for plastic gears, either as part of the plastic compound, or as a separately applied substance.  Silicone-based lubricants are generally used in addition to PTFE for aggressive applications.  You may need to consider the entire package (base resin, reinforcement, lubricant, etc.) if the wear is this significant.  LNP has some good resources on-line regarding thermoplastic gears, lubricants, etc.  The website is http:/// . RE: lubricating plastic gears TVP (Materials) 22 Jul 02 12:03 I forgot to mention that the publication is called A Guide to Plastic Gearing and can be accessed by clicking on Publications then Brochures and Bulletins and then the .pdf file. RE: lubricating plastic gears plasgears (Mechanical) 16 Dec 02 11:22 All the plastic suppliers recommend prelube of plastic gears even if there is no further lubrication. I have dumped plastic gears into a bath of synthetic oil, then centrifuged the batch and stored the lot in plastic bags. It will aid run-in and increase life.
