CAMROL — The Industry StandardIn 1937, McGill engineers invented the first needle bearing cam follower. Since that time, McGill has maintained itsleading position through the continuous development of new features and improvements to the CAMROL bearingproduct line.

As today’s leading manufacturer of quality cam follower bearings, McGill has developed many features to extendbearing life for a variety of operating conditions, lubrication requirements and application environments. McGilloffers the broadest range of cam follower bearings on the market with over 1,400 standard designs to choose from.

OverviewThe typical functions of a cam follower are to provide anti-friction support of linear movement or to follow thesurface of a cam. The CAMROL cam follower from McGill was designed to withstand the intermittent shock, loadingand precision requirements associated with these applications.

Superior DesignFeatures PromoteLonger Life,Lower CostAlthough others have tried to copy theoutward appearance of CAMROL bearings,our customers find vast differences inperformance. In laboratory testing, CAMROLbearings last up to 50 times longer thansome competitors in a variety of laboratoryand customer tests.

Eight bearings from eachmanufacturer were tested underidentical laboratory conditionswithout relubrication. CF–1-Ssize tested at 200 lbs and 1,500RPM.

ProvenPerformance

Heavy Sectioned Outer RaceThe heavy sectioned outer racewithstands shock loading of camfollower operation.

Lubrication Groove Extends Bearing LifeAll inch dimension CAMROL bearings with seals have a

lubrication groove that extends lubrication intervalsand increases the prelubricated life of the bearing.

CorrosionResistantFinishCAMROL bearingsare protected by ablack oxide finish onall external surfacesto prolong bearinglife by inhibitingcorrosion.

High QualityMaterialsAlthough other steelsmay be less expensive,McGill only uses highquality, specialty steel toboost the performanceand endurance that is thehallmark of a CAMROLbearing.

Specialized Heat TreatmentAll raceways are heat treated to a minimum of 58 HRC. Inner studs are induction heat

treated to McGill specifications to provide a hardened raceway and a ductile stem thatprovides toughness for absorbing the shocks of cam follower operations.

Improved Holding PowerThe threads on all inch CAMROL bearingstuds meet class 2 tolerances and metric

CAMROL bearing stud threads meet class 6Gtolerances. These precise geometrics help

ensure better holding power.

LUBRI-DISC Seal OptionThe LUBRI-DISC seal option increases bearing life up to 10 timeslonger than unsealed bearings:

• Labyrinth and contact sealing help protect against loss oflubrication and help prevent entrance of contaminantswhile providing low drag operation.

• Vents help prevent seal blow-out during relubrication.

• Integral backplate design reduces internal friction byeliminating metal-on-metal contact. Less friction lowersthe operating temperature, which extends grease life andallows for higher operating speeds.

Note: The LUBRI-DISC seal is rated up to 250°F maximum.

Hex Hole Option for Ease of InstallationThe hex hole option reduces costs by speedinginstallation or removal of stud type cam followers.During typical installation or removal, the bearingmust be held in place while torque is applied to themounting nuts. The optional hex hole increases secureholding power over the standard screwdriver slot in theface of the bearing. The hex hole option is standardfor stud type Heavy-Duty, Special-Duty and Corrosion-Resistant (CRES) CAMROL bearings and is an option forstandard CAMROL bearings.

The hex hole option is ideal for:

• Difficult to reach assemblies

• Blind hole mounting

• Equipment with many bearings

Note: The hex hole option does not allow for relubricationfrom the roller end of the bearing on most sizes. (All metricversions and inch sizes below 3" OD.)

Crowned OD Option for Long LifeA slight crown on the OD of a cam follower bearing can increase bearing life up to three times longer than the standard,cylindrical OD bearing. The crown helps more evenly distribute stresses for the following conditions:

•Heavy loading

• Misalignment of track or housing

• Turntable or rotary cams

Note: The crowned O.D. is an option for standard CAMROL and Heavy-Duty CAMROL bearings.

Non-metallic Bushing

Eliminates RelubricationThis bearing series eliminates the need forlubrication by utilizing a non-metallic bushinginstead of needle rollers. Save relubricationtime and inconvenience. This is ideal whenrelubrication is not desired and greasecontamination must be avoided.

The bushing type is appropriate for:

• Light loads and slow speeds

• Applications that do not involvecontact with food

HEAVY-DUTY

Heavy-Duty CAMROLfor Incidental Thrust ApplicationsWhile standard needle bearing cam followers are the economical choice for most applications, incidental thrustloads make Heavy-Duty CAMROL bearings a better choice. Primary causes of incidental thrust are misalignment ofhousing or track, high loading causing stud deflection and rotary tracks or cams. Heavy-Duty CAMROL bearingsemploy a unique internal construction, consisting of two rows of cylindrical rollers designed to manage much of thethrust.

Resists ContaminationRubber lip seals are standard in Heavy-Duty CAMROL bearings. Although standard cam followers do well in mostconditions, the rubber lip seals in Heavy-Duty CAMROL bearings increase protection against contamination.

Maintenance FreeSeals are pointed inward for improved grease retention. The large lubricant reservoir and rubber lip seals keep moregrease in the bearing for maintenance free operation.

Double Rows of Cylindrical RollersAllow for high speeds and a high dynamic rating

for extended fatigue life.
