Need a bearing that can roll along a cam track, or one that absorbs heavy axial load in a tight envelope? Those are two different jobs in the bearings and power transmission aisle, and the two bearings here are built for them. The RBC BearingCompany Industrial Cam Follower Roller Bearings, PN# S48L is a lot of six stud-type cam followers. The High-Capacity 3/8" Bore Thrust Needle Roller Bearings with Washers - 19kN Static is a compact thrust bearing for axial loads. This head-to-head sorts out which one belongs in your bearing assembly.
Quick Verdict
If your application calls for a flat roller with a 1.5000-inch roller diameter and matching stud diameter, the RBC S48L lot is the practical match. If your priority is heavy axial-load capacity in a small package, the NTA613 thrust needle bearing with its high static rating and high-speed capability is the better fit. The RBC product gives you multiple bearings from opened original boxes; the NTA613 is a new bearing built around a compact bore.

Where Each Product Wins
The RBC S48L wins when you need a stud-mounted cam follower with a matching stud size. The six-piece package gives you enough rollers to handle multiple positions or keep spares on hand.
The High-Capacity NTA613 wins for thrust-load applications. It carries a high static load rating and supports high rotation speeds, and its compact bore and outer diameter fit tight axial-load positions. It also costs less, at $7.99.
Product Notes
RBC BearingCompany Industrial Cam Follower Roller Bearings, PN# S48L

The S48L is a stud-type cam follower with a flat roller profile and a stud diameter that matches the roller. It arrives as a multi-piece lot from opened RBC boxes, so this is a practical way to stock several identical rollers at once. The flat face suits applications where a flat contact path is called for, and the part number gives you a clear reference for the profile. The limitation is the open-box condition: the lot is classified as new but the original packaging has been opened. If you need a sealed, untouched package, this lot may fall short.
High-Capacity 3/8" Bore Thrust Needle Roller Bearings with Washers - 19kN Static

This NTA613 uses chromium steel rollers, an ST13 steel cage, and 65Mn spring steel washers to manage heavy axial loads. It is rated for 7.75 kN dynamic load and 19 kN static load, with a 15,000 rpm maximum when lubricated with oil. Those numbers make it a strong candidate for a compact thrust position where axial force is the main concern. The trade-off is that this is a thrust bearing, not a cam follower: it handles axial loads, not the rolling contact of a track. You also need to plan for oil as the compatible lubricant.
Final Choice by Use Case
Choose the RBC BearingCompany S48L when your design needs a cam follower on a matching stud and you can work with a multi-piece lot. Choose the High-Capacity 3/8" Bore Thrust Needle Roller Bearings with Washers when axial-load capacity is the priority and oil lubrication fits your maintenance routine. For a thrust position, the NTA613 is the right part; for a track-rolling position, the S48L is the one to use.
