Follower Bearings CAMROLOutstanding PerformanceCAMROL SeriesCAMROL bearings outlast the competition in a variety of laboratory andcustomer tests. Although others have tried to copy the outward appearanceof CAMROL bearings, many customers have found vast differencesin performance. It is no wonder that so many customers specify“CAMROL bearings from McGill — no substitutions.”Longer Life Means Lower CostsManufacturers can reduce downtime due to premature failures andreduce maintenance costs by using McGILL bearings. With CAMROLbearings from McGILL, you can expect the same high levels of quality andperformance that our bearings have provided for years.Longer Life OptionsChoosing the right bearing for your application can make all the difference in getting longer life. In addition to choosing the correct size, someoptional features from McGILL can improve the life of the bearings beyondstandard bearing performance levels.Lubri-Disc SealsEccentric StudCam FollowerCrowned O.D. Cam FollowerLUBRI-DISC Seals help extend bearing lifein several ways:l Helps keep contaminants out — lubrication inl Vents in the seal help prevent blow-outduring relubricationl The integral backplate reduces internalfriction, which helps extend life by loweringoperating temperaturesEccentric Stud Cam Followers can havelonger useful life than standard stud bearingsin many applications. This option provides ameans of easily adjusting the precise radialposition of the bearing, which allows for:l Improved load sharing of in-line bearingcombinationsl Compensation for wear of track or outer ring.l Reduced tolerance requirements formounting hole positionCrowned O.D. Cam Followers can improvelife in applications because it reduces the possibility of edge loading of rollers.

CAMROL CamCAMROL Superior DesignDifferentiated Design Features Help McGill BearingsLast Longer Than The CompetitionHeavy-Sectioned Outer RaceWithstands shock loading of cam followeroperation.Lubrication GrooveAll inch dimension CAMROL bearings with sealshave a lubrication groove which helps extend thebearing life. This extra lubrication reservoirhelps prolong lubrication intervals and increasesthe prelubricated life of the bearing.Black Oxide FinishThis feature extends life by helping inhibitcorrosion. CAMROL bearings are protectedby black oxide finish on all external surfaces— unmatched by most competitors.Excellent Quality MaterialsOnly bearing quality steel is used in CAMROLbearings to help ensure long life. Although othersteels may be less expensive to use, McGill onlyuses high-quality specialty steel to providecustomers with the performance and endurancethey have come to expect from CAMROL bearings.Specialized Heat TreatmentAll raceways are heat treated to a minimumof 58 HRC. Inner studs are induction heattreated to McGill’s specifications to providea hardened raceway and a ductile stem thatprovides toughness for absorbing theshocks of cam follower operations.

Follower BearingsCAMROLThe LUBRI-DISC SealInvented by McGill, the LUBRI-DISCseal has been shown to reduce costs by prolonging bearing life. The seal helpsextend bearing life in three ways:1. Labyrinth and contact sealingprotect against loss of lubricant andhelp prevent entrance of contaminants.2. Vents help prevent seal blow-outduring relubrication.3. Integral backplate design reducesinternal friction by eliminating metalon-metal contact. Less friction lowersthe operating temperaturewhich extends greaselife and allows forhigher operatingspeeds.Precision GeometriesThe threads on all inch CAMROL bearingstuds meet class 2 tolerances and metricCAMROL bearing stud threads meet class6G tolerances. These precise geometrieshelp ensure better holding power. PRECISION BEARINGS

CAMROLCAMROL Cam Precision ManufacturingBecause there are no industry-wide standards for tolerances oncam follower bearings, McGill has set its own demanding tolerances for CAMROL bearings. McGill uses Statistical ProcessControl (SPC) to help ensure CAMROL bearings are manufactured according to these exacting standards. While others havetried to imitate the McGill design, only McGill has the precisionand performance that leads the industry.Quality Certified ManufacturingMcGill was one of the first bearing manufacturers to receiveInternational Standards Organization certification.
