McGILL

McGill® precision bearings are engineered to reduce operating cost and have evolved to meet the needs of an ever-expanding list of industries and applications since the CAMROL® cam-follower bearing was patented in 1905. CAMROL® bearings are now offered in more than 1,400 different combinations and configurations.

In 1937, McGill bearing engineers invented the first needle bearing cam follower and have since made innovations for aerospace and spherical bearings. System uptime and operational efficiencies are the goal, and the robust design unique to McGill bearings plays an important role by easing installation, reducing maintenance, and decreasing equipment downtime.

Even a small amount of dust, water, or other particulate matter contamination can significantly reduce bearing life. Because there are no industry-wide standards for tolerances on cam follower bearings, Regal has set its own demanding tolerances and uses statistical process control to help provide cam followers that are manufactured according to these exacting standards. In laboratory testing at Regal, CAMROL bearings last up to 50 times longer than some competitors' products in a variety of laboratory and customer tests.

CAMROL®, TRAKROL®, CAGEROL®, GUIDEROL®, SPHERE-ROL® and other McGill bearings provide operational efficiencies to a wide variety of industrial applications.

CAMROL® CAM FOLLOWERS

CAMROL® full complement needle bearings feature black oxide-treated bearing steel. They are available in two basic mounting styles for use in mechanical automation or linear motion applications. Our basic features each contribute to superior performance. The LUBRI-DISC™ seal option helps prevent metal-to-metal contact within the bearing. It also provides a barrier for containment entry and blowout protection when relubricating.

Features & Benefits

• Full complement needle roller construction provides high radial load capacity. It also provides improved resistance to shock loading versus caged needle bearing.
• Manufactured from bearing quality steel.
• A heavy-sectioned outer race design to help withstand shock loading of cam follower operation.
• Inner studs are induction heat treated in the roller path and flange surfaces only. The remainder of the stud is not hardened resulting in a ductile stem that provides toughness.

Specifications

• Cylindrical or Crowned OD
• Sealed or Unsealed
• Custom lubricants
• Screw driver slotted or Hex hole
• Standard stud, Eccentric stud, or Yoke roller
• Custom designs
• Inches CAMROL – available on ½” to 10” roller diameter
• Metric CAMROL – available from 13mm to 90mm roller diameter

TRAKROL® CAM FOLLOWERS

TRAKROL® bearings feature black oxide treated bearing steel. They utilize either a precision ball or tapered roller bearing insert for longer operating life under combination radial and thrust loads. The capacity for combination loads allows the TRAKROL bearing to be available in plain (cylindrical), V-groove, and flanged O.D. in both stud and yoke styles. Small sizes (<3” OD or point diameter) use sealed ball bearing inserts. They also use a NYLAPLATE® seal for additional protection. Stud type configurations utilize a metal end plug seal on the roller face providing a long lasting seal. Both bearing types provide a large internal grease reservoir along with special sealing. This makes TRAKROL bearings an excellent choice where reduced maintenance is required

• Black oxide finish on all external surfaces helps inhibit corrosion
• Ball and Tapered Roller Bearings have rubber lip contact seal. Additional NYLAPLATE seal present on 1 ½" to 2 ¾" stud type versions. End plug present at outboard side of stud type versions to help keep contaminants out and lubrication in
• The threads are manufactured to a class 2 tolerances
• Bearings are supplied pre-lubricated and maintenance free
• Standard sizes and custom designs available upon request

Specifications

• 1 ½ “ to 8” diameters
• Cylindrical, V-Groove or Flanged OD
• Custom designs
• Hex Socket hole
• Standard stud, Eccentric stud and Yoke roller
• Custom lubricants

CAGEROL® NEEDLE BEARINGS

CAGEROL® machined race needle bearings are manufactured from bearing quality steel with contoured rollers, when beneficial. This helps reduce end stresses and allows for greater misalignment. The rollers are separated by a steel retainer (cage) to help achieve higher speeds and provide a lubricant reservoir. CAGEROL bearings are constructed with a radial lubrication hole and a groove on the outer raceway. We also offer an optional inner raceway (MI-series) for relubrication through the housing or shaft.

Other options include a variety of seal configurations to either help prevent contaminate entry or contain the lubricant. Depending on your preference, these bearings are available in a wide variety of sizes and options.

Machined Outer Race

Race manufactured from bearing quality steel and hardened to carry heavy dynamic and static loads. Needle Rollers with End Relief (Most Sizes). Precision Needle Rollers provide high radial load capabilities in small radial envelope dimension. End relief features help reduce raceway stress when shaft misalignment occurs.

Steel Cage

Welded construction minimizes roller radial play for ease of assembly and provides roller guidance helping to reduce friction. The spacing provided by the retainer contributes to the high speed capabilities and lubricant reservoir within the bearing envelope.

Annular Lubrication Groove

The groove provides a circumferential path to direct lubricant to the hole when lubricating through the housing.

Factory Grease Fill

Sealed CAGEROL bearings are factory lubricated with a medium temperature (-30° to 250°F, -34° to 121C) NLGI 1 grease. Unsealed bearings are packaged with a light oil film as a rust preventative. Contact Application Engineering when application conditions require special lubricants.

Seals

The rubber lip seal is capable of 250°F maximum temperature and is available in several different configurations.

"DS" Matched Bearings - Load Sharing

Where two bearings are installed, load sharing should be encouraged when the distance between is less than the width of one bearing. To accomplish this, it is recommended that the bearings be diametrically matched. The option, when applicable, matches OD and ID tolerances. It also maintains diametrical clearance within 30% of the tolerance range and the radial runout within 20% of the tolerance range. The high point of runout is indicated on the bearing faces. For more information and matching factors please review the engineering section for matched bearings. Matched bearings packaged as sets.

Machined Inner Ring(MI)

Precision ground inner ring provides a hardened raceway for the rollers when used with an unhardened shaft. The ring contains an oil hole and annular groove relubrication of the bearing. It can be used with both CAGEROL and GUIDEROL® bearings. It can also be utilized as a bushing in plain bearing applications.

Grease Options

When requested, standard bearings can be factory filled with customer specified lubricant.
