CAMROL cam follower selection guide
CAMROL Bearing— The Industry Standard
Since 1937, the McGill brand has maintained its leading position through the continuous development of new features and improvements to the
CAMROL bearing product line. As of today’s leading manufacturer of quality cam follower bearings, Regal has developed many features to extend
bearing life for a variety of operating conditions, lubrication requirements, and application environments. The McGill brand offers a broad range of cam
follower bearings with over 1,400 standard designs to choose from.
The typical functions of a cam follower are to provide anti-friction support of linear movement or to follow the surface of a cam. The CAMROL
cam follower from Regal was designed to withstand the intermittent shock, loading and precision requirements associated with these applications.

Superior Design Features
Promote Longer Life,
Although others have tried to copy the
the outward appearance of CAMROL®
bearings, our customers find vast differences
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.
- Automation equipment
- Machine tools
- Packaging equipment
- Unit material handling
Eight bearings from each manufacturer were tested at
Regal under identical laboratory conditions without re-lubrication.
CF–1-S size tested at 200 lbs and 1,500 RPM.
Metric Cam Follower Bearings
Regal offers metric CAMROL bearings in metric dimensions
equivalent to ISO standard series. Both European and Asian
versions are available.
Metric CAMROL bearings are available
in stud or yoke type versions. Specifying the type of bearing
needed depends upon the preference for either a straddle (yoke)
mounting or a cantilever (overhung) mounting.
Metric CAMROL bearings are available with three types
of internal construction: full complement needle rollers, retainer
type needle rollers or cylindrical rollers. With a proven track record
on inch cam followers, Regal brings many key features and
manufacturing practices to the metric CAMROL series that outlast
In test laboratories, McGill CAMROL bearings last up to 24 times
longer than some competitors' bearings.
Eight bearings from each manufacturer were tested at Regal
under identical laboratory conditions without re-lubrication.
MCF-26-S size tested at 160 lbs and 1,975 RPM.
Heavy Duty Metric CAMROL BearingsThis series provides greater dynamic load ratings by using cylindrical rollers in place of standard needle rollers.
This construction allows the bearings to support radial loading, as well as some axial loading.
MCFD Series Bearings
MCYRD® Series Bearings
Yoke type heavy-duty metric CAMROL bearings are designed for yoke (straddle) mounting on a shaft.
LUBRI-DISC Seal Option
The LUBRI-DISC seal option increases bearing life up to 10 times longer than unsealed bearings:
- Labyrinth and contact sealing help protect against loss of lubrication and help prevent entrance of contaminants while providing low drag operation.
- Vents help prevent seal blowout during re-lubrication.
- Integral back-plate design reduces internal friction by eliminating metal-on-metal contact. Less friction lowers the operating temperature, which extends grease life and allows for higher operating speeds.
Hex Hole Option For Ease Of Installation
The hex hole option reduces costs by speeding the installation or removal of stud-type cam followers. During typical installation or removal, the bearing must be held in place while torque is applied to the mounting nuts. The optional hex hole increases secure holding power over the standard screwdriver slot in the face of the bearing. The hex hole option is standard for stud type Heavy-Duty,
Special-Duty and CRES corrosion-resistant CAMROL bearings and is an option for standard CAMROL bearings.
The hex hole option is ideal for:
- Difficult to reach assemblies
- Blind hole mounting
- Equipment with many bearings
Crowned OD Option For Long Life
A 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
- A turntable or rotary cams
Note: The crowned O.D. is an option for standard CAMROL and heavy-duty CAMROL bearings.
Misalignment can cause corner loading
Computer Analysis Shows
Crowned OD Can Increase
Life Three Times Longer.
Finite element analysis of cam followers under heavy loads
shows crowned OD increases L10 life. More detailed results
available in Motion System Design magazine, August 2003.
Special-Duty CAMROL Bearings
For Tough Environments
Select special-duty CAMROL bearings for tough applications
such as automotive production, metal forming assembly and
Corner loading is reduced.
Special-duty CAMROL bearings are specifically designed to resist contaminated environments. A metal end plug seal on the roller face helps block out
contamination and resists welding spatter.
Special-duty CAMROL bearings extend bearing life up to six times without lubrication maintenance by using synthetic grease and caged needle rollers.
Caged needle rollers allow for a larger grease reservoir than standard needle bearing cam followers, a beneficial feature when re-lubrication is not possible.
On the stud side of the Special-duty CAMROL bearing, the LUBRI-DISC + seal offers improved protection over standard sealing.
BUSHING TYPE CAMROL BEARINGS
Cam Follower Bearings
This bearing series eliminates the need for lubrication by utilizing a non-metallic bushing instead of needle rollers. Save re-lubrication time and inconvenience.
This is ideal when re-lubrication is not desired and grease contamination must be avoided.
The bushing type is appropriate for:
- Light loads and slow speeds
- Not for food applications
Heavy-Duty CAMROL Bearings
For Incidental Thrust Applications
While standard needle bearing cam followers are the economical choice for most applications, incidental thrust loads make Heavy-duty CAMROL bearings a
better choice. Primary causes of the incidental thrust are a misalignment of housing or track, high loading causing stud deflection and rotary tracks or cams.
Heavy-duty CAMROL bearings employ a unique internal construction, consisting of two rows of cylindrical rollers designed to manage much of the thrust.
Rubber lip seals are standard in Heavy-duty CAMROL bearings. Although standard cam followers do well in most conditions, the rubber lip seals in Heavy-duty
CAMROL bearings increase protection against contamination.
The standard bearing has no re-lubrication feature. Seals are pointed inward for improved grease retention. The large lubricant reservoir and rubber lip seals
keep more grease in the bearing for maintenance-free operation.
CRES CAMROL Cam Follower Bearings
Corrosion-Resistant CAMROL Bearings for Food and Beverage Applications
Greater Corrosion Resistance
Whether equipment is exposed to the elements or to extreme washdown in food and beverage applications, the CRES corrosion-resistant CAMROL bearing series extends bearing life in wet or corrosive environments compared to standard cam followers. The CRES CAMROL bearing features 400 series stainless steel to help prevent corrosion.
FDA Compliant Grease
CRES CAMROL bearings utilize H1 FDA compliant grease for food applications.
The LUBRI-DISC + seal provides up to five times better protection against wash-down than standard seals. This seal is featured in CRES CAMROL bearings 1” OD and larger.
Tested per ASTM B117 salt fog test, 5% saline solution,
100°F, 100% humidity.
Water Spray Comparison
In a test originally performed to meet exacting aerospace
standards, CRES CAMROL bearings were tested with
a high-pressure spray aimed at the bearing face. This graph
shows how each seal held-up – the LUBRI-DISC + seal featured
in CRES CAMROL bearings was the obvious winner.
TRAKROL Cam Follower Bearings
For Thrust and Contamination
TRAKROL bearings feature a different design than CAMROL bearings to allow for heavier thrust loads. Smaller sizes (< 3” OD or point diameter) use
ball bearing inserts and larger sizes use tapered roller bearings to accept thrust loads.
Rubber lip seals help keep out contamination on the stud side of the bearing and a metal end plug seal helps protect the roller face.
Tapered roller bearing or ball bearing inserts allow for the heavier thrust capabilities of the TRAKROL bearing.
A large grease reservoir allows for a longer life without re-lubrication.
- Three OD types (plain, flanged and V-groove)
- Stud and yoke types
- Eccentric stud option available
Note: TRAKROL bearings are not always dimensionally interchangeable with CAMROL® bearings.
Yoke TRAKROL® Bearings
Yoke TRAKROL® bearings are designed for yoke (straddle) mounting on a shaft and utilize tapered roller bearings.
Available in three configurations.
