Open the catalog to page 1Black Racer Family Linear Ball Bearing Family Mike Quinn is VP Sales & Marketing at LM76 Please call me with any questions: 617-538-8756 Since 1976 LM76 has been helping engineers solve their most desperate linear applications. Our Black Racer Ceramic Coated linear bearings are without equal when compared to PTFE, plastic and linear ball bearings. Case in point, linear ball bearings must be greased - the same with our Black Racer Ceramic Coated Bearings. Do linear ball bearings offer a lower coefficient of friction - yes - but so low they blow the Black Racer out - NO. The Black Racer will...
Open the catalog to page 2If you lubricate, there is no equal in performance or price! BLACK RACER, CERAMIC COATED LINEAR BEARINGS™ The “original” drop-in replacement for linear ball bushings, our Ceramic Coated bearing is simply awesome in applications where traditional linear ball bushings fail. Ceramic Coated bearings require lubrication - either a grease or light oil. They excel in “ Hellish “ environments, operate with a low Coefficient of friction ( .04 - .08 ) and outlast any comparable product: .00004” wear after 100 million linear FEET! OVER 100 G’s Acceleration! To date, we are not aware of any application...
Open the catalog to page 3Minuteman PTFE composite linear bearings offer a tough, hard ceramic coated aluminum shell which does not chip, flake or generate debris. Bonded to the bearing shell ID is our Minuteman - Green - PTFE , self-lubricating liner which ranges from .025" - .035" thickness depending on bearing size. Minuteman's self-lube PTFE linear is not filled with abrasive materials like glass or metallics that require hardened steel or 440c stainless shafting. Rather, our blend employs high load, non-abrasive polyimide fillers which are able to run on soft, 300 series stainless steels- 303, 304 and 316 SS....

In order to achieve maximum performance of the LM76 Ceramic bearing, a lubrication method is essential. The proper amount of lubrication required is that amount which maintains a constant thin film...
Open the catalog to page 11Performance Data (Ceramic Series) Linear Motion Performance Data Rotar Motion Performance Data Temperature Limitation PV limits as applied to plane bearings vary depending upon the manufacturer's testing procedures. The PV limit for the LM76 bearing was determined to be that point in the testing where the constant coefficient of fric- tion (e.g. .04 increased to .05) remained at that level or higher. At that point, the test was terminated and that load and speed was determined to be the PV limit. Therefore, it should be noted that the PV limit only sig- nifies an increase in friction, and...
