When you're working in bearings, couplings, and power transmission, the first question isn't just "which brand?"-it's which bearing type fits the motion. A cam follower with a stud is built to track along a rail or guide, while a cylindrical roller bearing sits in a bore and carries heavy radial load. This head-to-head compares a lot of RBC S48L cam followers with an AXIS NU315 EMC3 cylindrical roller bearing. One is a quantity play for guided motion; the other is a direct replacement for conveyor and drive maintenance.
Quick Verdict
Choose the RBC S48L lot if you need several cam followers for track-guided positions and you can work with as-is surplus. Choose the AXIS NU315 if you need a cylindrical roller bearing with NU315 dimensions for a conveyor or drive replacement.

Where Each Bearing Wins
The RBC lot wins on upfront price and on giving you multiple parts at once, which matters when a track has many roller positions.
The AXIS wins on its NU315 replacement profile and its fit for conveyor and drive service rather than cam tracking.
Product Notes
RBC BearingCompany Industrial Cam Follower Roller Bearings, PN# S48L
This lot of six RBC cam followers is priced at USD 40.00, which makes the per-part cost low for an industrial roller batch. The flat 1.5 in roller and 1.5 in stud are useful for guided track setups where you need the cam follower to ride against a surface. The trade-off is the condition: original RBC boxes were opened, and the lot is as-is with no warranty, no returns, and no refunds. If you can inspect each roller and accept that there's no recourse, the S48L lot is a practical way to stock a row of positions. If you need a formal warranty or sealed-box peace of mind, this lot doesn't offer that.
AXIS NU315 EMC3 Cylindrical Roller Bearing Heavy Duty Industrial Replacement
The AXIS NU315 is a new cylindrical roller bearing from the NU300 series, with an inside diameter of 75 mm, an outside diameter of 160 mm, and a 37 mm length through bore. It is aimed at conveyor, drive, and maintenance-replacement use, so it fits the classic cylindrical roller job rather than a cam follower role. This is a single bearing, not a multi-piece lot, so you're buying one replacement for one position. The reason to choose it is the combination of new condition and NU315 sizing: you get a fresh part with matched dimensions for the intended housing. The limitation is that one bearing covers one position; if your project needs more NU315s, you'll need to order each one separately.
Final Choice by Use Case
For a guided track or cam-driven mechanism that needs multiple roller positions, the RBC S48L lot gives you a multi-piece set of cam followers suited to track-guided positions. Expect to inspect the rollers before you put them to work.
For a conveyor, drive unit, or manufacturing-machine replacement that calls for an NU315, the AXIS is the part to order. It brings NU315 sizing for the replacement job.
