What Is the REVO RCBS30-2A Cam Follower?

The REVO RCBS30-2A is a stud-type cam follower (track roller bearing) designed to run on linear tracks, cam surfaces, or guide rails. It features a thick-walled outer ring to withstand heavy radial loads and shock loading, with a threaded stud for direct mounting into machine structures. Common in automated machinery, indexing mechanisms, conveyor systems, and linear motion guides where rolling contact replaces sliding friction.

In short: A REVO stud-type cam follower bearing — a heavy-duty track roller that follows cam profiles and guides linear motion in automated machinery, conveyors, and indexing systems.

Key Features

1. Heavy-Duty Outer Ring Construction

What it means: The outer ring is significantly thicker than a standard ball bearing — designed to absorb impact and rolling contact stress.
Why it matters: Cam followers see concentrated point-contact loads that would brinell (dent) a standard bearing race.
Result: Long service life under the repeated impact and rolling fatigue conditions of cam-driven machinery.

2. Stud-Type Mounting

What it means: An integral threaded stud allows direct mounting into a tapped hole, with a hex socket or wrench flats for tightening.
Why it matters: Eliminates the need for a separate shaft, housing, and retaining hardware — one component provides both bearing and mounting.
Result: Simplified mechanical design with fewer parts and faster assembly.

3. Crowned or Cylindrical Outer Ring

What it means: The outer ring profile is optimized for either pure radial loads (cylindrical) or combined radial/thrust loads with some misalignment tolerance (crowned).
Why it matters: In real machinery, alignment is never perfect — the correct profile prevents edge loading and premature failure.
Result: Reliable operation even with the slight misalignment inherent in fabricated machine frames.

Key Specifications

Typical Applications

• Cam-Driven Indexing Mechanisms: Following barrel cams and plate cams that convert rotary motion to intermittent linear or oscillating motion in assembly machines.
• Conveyor Side Guides: Acting as rolling guides that keep product aligned on belt conveyors without the friction and wear of fixed guides.
• Linear Slide Systems: Supporting carriage motion along hardened guide rails in pick-and-place and material handling linear actuators.
• Packaging Machine Folding Stations: Following cam profiles that control carton flap folding and tucking sequences in high-speed packaging lines.

Frequently Asked Questions

"How do I select the right cam follower for my load?"

Cam follower selection is based on radial load capacity (static and dynamic), the nature of the loading (steady vs shock), speed, and operating environment. The static load rating must exceed the maximum expected load with a safety factor of at least 2. For dynamic (rotating) applications, calculate the L10 bearing life based on the equivalent radial load and the dynamic load rating.

"What lubrication does this cam follower need?"

Most stud-type cam followers are pre-greased at the factory with a lithium-based NLGI 2 grease. They require periodic re-greasing through the grease fitting (if equipped) or the stud end. Greasing interval depends on speed and load — as a guideline, re-grease every 500 operating hours or 3 months in continuous-duty applications. In washdown environments, more frequent greasing pushes out water and contaminants.

"Can this cam follower tolerate axial (side) loads?"

Stud-type cam followers are primarily designed for radial loads. Moderate axial loads can be tolerated if the outer ring profile is crowned, which distributes edge stress. For applications with significant combined radial and axial loads, a yoke-type cam follower with separate axial support or a dedicated thrust bearing arrangement may be required.
