CF-18 is a cam follower (stud-type track roller) in the CF series, with confirmed dimensions of d18 × D40 × B20 (mm). In this type of component the outer ring rolls directly against a track or cam surface, so it is commonly found in cam mechanisms, guide rollers, conveying and transfer equipment, and automated pick-and-place systems—positions that carry radial load while running along a track. Whether CF-18 suits your position still depends on your actual speed, load and track contact conditions.
How a cam follower performs is closely tied to the contact between the outer ring and the running surface. Conditions worth evaluating together usually include: track surface hardness and finish, actual radial and shock load, running speed, and lubrication and operating temperature. The same size can behave quite differently across track materials and load patterns, which is why dimensions alone don't always tell you whether it fits. Sharing your speed, load and operating temperature helps us assess further.
A common situation: you already know the size you need, but you're not sure it will hold up under your own conditions. Rather than matching the dimension table alone, it helps to clarify the application first. If you can share three key inputs—running speed, load, and operating temperature—we can usually make an initial assessment. If you already have a model number, drawing or sample, feel free to include it, and we'll confirm against your actual conditions.
ISK Bearings has focused on bearing manufacturing since 1991, with products exported to more than 50 countries and certifications including IATF 16949, RoHS, REACH and SGS. Our facilities include an in-house heat treatment plant and 100% automated quality inspection. Cam follower outer rings depend on consistent surface hardness and dimensional control—exactly where these processes matter. For special operating conditions or custom requirements, share the details with your inquiry and ISK will confirm feasibility against the actual product.
If you're evaluating CF-18 or an alternative for a specific position, share your running speed, load and operating temperature—along with any existing model number, drawing or sample—and we'll help assess the fit and provide a quotation.
Some non-standard or currently out-of-stock bearings may not be immediately available. If you have specific requirements, feel free to contact us — we will do our best to confirm lead times and provide alternative solutions.
