CAMROL Cam Follower Selection Guide

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 the competition.

In test laboratories, McGill CAMROL bearings last up to 24 times longer than some competitors' bearings.

 

Proven Performance

Eight bearings from each manufacturer were tested at Regal under identical laboratory conditions without re-lubrication.









Heavy Duty Metric CAMROL Bearings

This 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

Note: The hex hole option does not allow for re-lubrication from the roller end of the bearing on most sizes. (All metric versions and inch sizes below 3” OD.)

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



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 welding environments.

Resist contamination

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.

Maintenance free

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.

Improved Protection

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

Eliminates Re-lubrication

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.

Resist Contamination

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.

Maintenance Free

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.

 

Improved sealing

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.

Rust Comparison

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.

Resists Contamination

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.

Thrust Applications

Tapered roller bearing or ball bearing inserts allow for the heavier thrust capabilities of the TRAKROL bearing.

Maintenance Free

A large grease reservoir allows for a longer life without re-lubrication.

Wide Selection

  • 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.
