Heavy-Duty CAMROL® Bearings

The Industry Leader...In 1937, McGILL engineers invented the first needle bearing cam follower. Since that time the McGILL®

CAMROL® Bearing line has maintained its leadership position through development of innovative solutionsto the problems faced by industry.

The Problem Solver...Heavy-DutyMcGILL® Heavy-Duty CAMROL® bearings are designed to help solve some of the toughest problems inyour cam follower applications. Utilizing Heavy-Duty CAMROL® Bearings in situations involving inciden-tal thrust loads, higher speeds, contamination, or maintenance-free operation can provide significantoperational life increases over standard cam followers.

Improved Thrust CapabilityStandard needle bearing cam followers are designed to handleheavy radial loads, however, thrust loads can cause early failure.

1. Double Rows of Cylindrical Rollers are designed in thebearing to help it take incidental thrust sometimes associatedwith cam follower operation. The double row of cylindrical rollersalso allows for high speeds and a high dynamic rating forextended fatigue life.

Maintains McGILL Quality FeaturesThe Heavy-Duty CAMROL® Bearing was designed with toughapplications in mind, and maintains a quality, robust design uniqueto McGILL.

2. Zone Hardened raceways provide high load ratings, and theductile stem gives strength for absorbing shocks.

3. Integral Flange in the stud type prevents disassembly in thrustload situations.

4. Center Thrust Ring provides a smooth surface for thrust loadcarrying and roller guidance.

5. Endplate Retention Ring in the yoke-type is an innovativemethod for securing endplates, eliminating the need for endplatebackup in certain applications.

Heavy-Duty CAMROL® Bearings

Resists ContaminationEven a small amount of contamination can significantly reducebearing life. Dust can wick oil out of the bearing, water can washgrease out, and particulate matter or contamination can dentraceways.

6. Rubber Lip Seals are standard in the Heavy-Duty CAMROL®

Bearings. Although standard cam followers do well in mostsituations, at times, seals such as those in the Heavy-DutyCAMROL® Bearing are needed for increased protection againstcontamination. The rubber lip seals are pointed inward forimproved grease retention.

Provides Lube-For-Life OperationHeavy-Duty CAMROL® Bearings last up to 5 times longer thanstandard needle bearing cam followers in lube-for-life tests.

7. Large Lubricant Reservoirs and rubber lip seals help keepmore grease in the bearing for maintenance-free operation.

Up to Five Times Longer Life
