Picking the right bearing for a power transmission or industrial maintenance job usually comes down to three things: shaft fit, load capacity, and listed price. These four bearings cover that range in very different ways. One AXIS flange bearing is built around a compact bore, another steps up to a larger bore, a third is a water pump replacement unit, and the C&U NJ216ETN1/C3 is a cylindrical roller bearing aimed at tougher load positions. The decision is less about good versus bad and more about matching the bearing to the space and stress it will see.
Quick Take
These four bearings split into two broad jobs. The AXIS AF2436 and AF6464 are flange bearings for specific shaft sizes, the AXIS 885586SE is a water pump bearing, and the C&U NJ216ETN1/C3 is a cylindrical roller bearing built for demanding power transmission positions. Listed prices run from USD 14.96 to USD 149.99, so matching the bearing to the work matters more than the range.
Listed-Price Comparison
| Product | Listed Price | Price Bar |
|---|---|---|
| AF2436 Commercial Grade | USD 14.96 | |
| 885586SE Water Pump | USD 19.67 | |
| AF6464 Commercial Grade | USD 22.78 | |
| C&U NJ216ETN1/C3 | USD 149.99 |
Decision Matrix
- Choose the AF2436 when you need a compact steel flange bearing with a 0.375-inch bore and tight clearance.
- Choose the AF6464 when your shaft bore is 1 inch and you have room for a 2-inch outside diameter.
- Choose the 885586SE when you are replacing a water pump bearing and the part number matches the unit in your pump.
- Choose the C&U NJ216ETN1/C3 when the application calls for cylindrical roller bearing capacity.
Product Notes
AXIS AF2436 Commercial Grade Bearing
The AF2436 is the smallest AXIS unit here. It has a 0.375-inch bore, a 1.125-inch outside diameter, a 0.4375-inch length through bore, and a 1.25-inch flange diameter. That makes it a natural fit for light-duty shafts and crowded machinery where the larger AF6464 will not clear the surrounding parts. The 0.088-pound weight also makes it easy to stage before installation. Its compact bore keeps it out of 1-inch-shaft territory, so pair it with jobs that genuinely call for a small-diameter bearing.
AXIS AF6464 Commercial Grade Bearing
The AF6464 is the larger flange bearing in the AXIS pair. It moves up to a 1-inch bore, a 2-inch outside diameter, a 0.5-inch length through bore, and a 2.1875-inch flange diameter, with a 0.290-pound weight. If your machine already runs a 1-inch shaft and has housing space for a 2-inch bearing, this is the straightforward match. The trade-off is physical size: the wider flange and bigger bore will not tuck into the same tight pocket as the AF2436.
AXIS 885586SE Water Pump Bearing
The 885586SE is the only water pump bearing in this group, with the part number serving as the direct replacement reference and the SE Series name tying it to AXIS's pump-bearing line. The 0.710-pound weight is the heaviest of the three AXIS units, which fits the role of a pump bearing that has to sit in a rotating pump assembly. Keep the rest of the pump's shaft and housing dimensions handy so you can confirm the fit before tearing down the old unit.
C&U Bearings NJ216ETN1/C3 Industrial Cylindrical Roller High Load Bearing
The C&U NJ216ETN1/C3 is a different animal from the AXIS flange bearings. It is a cylindrical roller bearing, and its title calls out high load directly. That alone tells you it is aimed at power transmission positions where radial load is the main concern. It is listed as new, with the NJ216ETN1/C3 part number identifying the specific bearing family. You will want to match it to your shaft and housing bore before ordering, because this is not a flange unit with a pre-set footprint like the AXIS bearings.
Final Recommendation by Use Case
Match the bearing to the machine, not the other way around. For a 0.375-inch shaft with tight clearance, take the AF2436. For a 1-inch shaft in an industrial mount, the AF6464 is the larger flange option. For a water pump replacement where the 885586SE number matches the original part, that bearing is the direct pick. For a high-load cylindrical roller position, the C&U NJ216ETN1/C3 is the specialist.
