Imperial Cam Followers
We've spent years supplying imperial cam followers and specialized solutions across industries that push bearings to their limits. Our experience covers everything from high-speed engines to contaminated agricultural environments, ensuring we provide the right cam follower bearings for every unique challenge.
Our cam followers work in:
- Engine valve trains operating at high speeds where precision matters
- CNC machines with 4th and 5th axis rotary tables and precision lathes
- Robotics applications including pick-and-place systems and articulated arms
- Can making machinery running continuous production under eccentric loads
- Textile machines with high-speed spinning and weaving operations
- Agricultural equipment working in dirty conditions with dust and moisture contamination
Applications Across Industries
Our imperial cam followers handle radial, axial, eccentric, and shock loads whilst working in harsh environments, dust, moisture, temperature extremes, and corrosive atmospheres.
- Printing Machines – Registration systems and feed mechanisms where accuracy counts
- Heavy Industrial Mining – Conveyors, crushers, and processing kit handling extreme loads
- Oil and Gas – Drilling rigs, pumps, and subsea gear in corrosive conditions
- Nuclear – Critical systems needing cam follower bearings with full traceability and low-cobalt materials.
Common Bearing Failures We've Sorted Out
Premature Failure Due to Eccentric Loads: Misalignment and eccentric loading account for many cam followers failures. We've fixed these problems by specifying crowned roller imperial cam followers that handle angular misalignment, spreading loads evenly and stopping the edge loading that wears bearings quickly.
Speed-Related Failures: Running cam follower bearings too fast cause centrifugal forces to make internal components skid instead of rolling properly. We've tackled this with crowned roller variants or hybrid ceramic bearings that run 20-30% faster than standard steel types.
Contamination and Seal Failure: Standard seals don't work well in dusty conditions. We handle this by picking the right seals for imperial cam followers, using fully sealed units that keep out even tiny particles.
Installation-Induced Damage: We see many cam followers wrecked during fitting, wrong mounting methods or poor shaft and housing tolerances are usually to blame. Our technical support walks clients through the critical installation steps.
What We've Learnt From Real Installations
Shaft Surface Finish Matters More Than You Think: Textbooks give you tolerances, but our experience with imperial cam followers shows that surface finish is often more important. We've seen installations that looked perfect on paper fail because rough shafts created stress points. A better surface finish can add years to bearing life in tough applications.
Temperature Changes Everything: Cam followers bearings fitted perfectly at room temperature can become loose and rattling when they heat up in ovens or engine parts. We've had to learn the hard way about thermal expansion differences between shafts and bearings, often fitting tighter than the standard recommendations say.
"Clean" Environments Aren't Really Clean: Even in CNC workshops that look spotless, microscopic metal chips find their way into cam followers. Rather than trying to make things perfectly clean (which is impossible), we've found it's better to add extra shields or use cam followers with proper sealing.
Multiple Bearings Never Share Loads Evenly: When several cam followers share a load, the theory says they'll split it evenly. Reality is different, manufacturing tolerances and deflection mean one or two bearings usually carry more than their share. We size our cam follower bearings knowing this will happen.

Where Specialist Knowledge Makes the Difference
Nuclear Applications: Nuclear work demands complete traceability every component needs full material certification and manufacturing records. We supply imperial cam followers with low-cobalt materials (to avoid radioactive activation) and enhanced corrosion resistance for the harsh decontamination chemicals used.
Motorsport Applications: In F1 and endurance racing, every gram counts. To address this razor’s edge, we supply lightweight cam followers with hollow rollers. We also improve cage designs to reduce drag and weight.
Clean Room Environments: Pharmaceutical and semiconductor manufacturing must be contaminant free. This is a non-negotiable. We specify stainless steel imperial cam followers with solid lubricant coatings that will not leak oil. To boot, they can also handle aggressive cleaning chemicals and steam sterilization.
How We've Helped Customers
Cutting Lead Times: Manufacturers often face long waits from suppliers, forcing them to stockpile bearings. We keep common sizes of imperial cam followers in stock and deliver quickly, helping customers reduce inventory whilst avoiding production stoppages from stock-outs.
Making Bearings Last Longer: Equipment often has a short bearing life because someone specified standard products without really looking at the application. We've dug into operating conditions and found better cam follower bearings like crowned roller variants, for instance, that have doubled or tripled service life and cut warranty claims.
