FOREWORDThis publication was designed to serve as a quick reference to the standard product series offered by INA USACorporation (INA) for its domestic market. The guide provides a current overview of INA products, including basicenvelope dimensions and capacities, in one publication –it is not an engineering design guide intended to replaceINA engineering catalogs. Consequently, the metric andinch conversions are listed to 3 decimal places for easyreference and rapid identification of correct replacementpart(s), not 4 decimal places as necessary for qualitycontrol purposes.This publication can be used to narrow the choices between the many different INA product lines and series fornew designs. Detailed engineering information for newdesigns can be found in our traditional catalogs or bycontacting the INA Engineering Department.A significant portion of INA sales are special productionsizes. The identification of those parts is sometimes difficult since a comprehensive listing is beyond the intent ofthis publication. Special part numbers take as many different forms as the series listed here, but the basic system is to use sequential numbers for each new design.Usually the prefix is F or FC but can include VH, INA orthe bearing type such as NA. INA maintains a technicalhelp desk to identify sizes not known or to match competitors’ parts.The toll free 800 numbers listed will give you access toINA Customer Service representatives. These representatives can tap into INA Worldwide resources to providethe bearings you need.Storage LifeLubricants age naturally due to environmental influences.It is therefore the user’s responsibility to follow the directions given by the lubricant manufacturer.The greases used in INA rolling bearings have a mineraloil base and experience shows that they can be stored forup to 3 years without deteriorating providing the followingimportant conditions are met.D Closed storage roomD Temperature between 0 C and 40 CD Relative atmospheric humidity 65% or lessD Security from chemical agents(vapors, gases, fluids)D Sealed rolling bearingsThe frictional torque can be considerably higher after linger storage periods than in freshly greased bearings andthe lubricity of the grease can also have deteriorated.INA bearings have many optional features available including:D ISO series of bearings generally include the standard clearance options CN, C2, C3 and C4.D ISO bearing series include PN, P6 and P5 precisionclasses.D Corrotect plating is available for most bearing designs. Corrotect is a patented process for zinc–ironand zinc–iron–cobalt plating in a thin layer which canbe applied to standard components. The protectionexceeds stainless steel and the cost is half. Addsuffix RR.D All sealed bearings are supplied pregreased. Inmost cases the standard lubricant is Shell Alvania 2or equivalent. Other greases are available, some atextra cost.D Unsealed bearings may not be greased whenshipped.D Speed limits as published, are based on oil lubrication for open bearings or grease lubrication forsealed bearings. The speed limits are calculatedbased on a nominal load and heat balance equation.Higher speeds may be allowed depending on theapplication.D Dynamic capacities are published based on INAstandard usage of ISO and ABMA formulas. Newlife theory threshold values are published in otherINA publications.D Life calculations and evaluations can be made fromINA engineering based catalogs which are availablefrom your INA Sales Representative.D Other features are available based on current production volumes including heat stabilization of therings, matched bearing sets, with oil holes andgrooves, etc.ABMAASTMDINISOAmerican Bearing Manufacturers AssociationAmerican Society Of Testing And MaterialsDeutsches Institut für Normung e.V.International Standards OrganizationElges, Andrews and Corrotect are registered trademarks ofINA USA Corporation.Permaglide is a registered trademark and a product ofKOLBENSCHMIDT AG, Neckarsulm, also produced inGreensburg, Indiana, USA.All other products and company names are trademarks or registeredtrademarks of their respective companies.ALL RIGHTS RESERVEDINA USA Corporation308 Springhill Farm RoadFort Mill, SC 29715Reproduction of this publication in whole or in part without the expresswritten consent of INA USA Corporation is prohibited.Although every effort has been made to ensure the accuracy of theinformation contained in this catalog, INA shall not be liable for anyomissions or errors.
