PRODUCT DETAILS
Cylindrical Roller Bearings
We supply full‑range cylindrical roller bearings manufactured in China. Cylindrical roller bearings adopt line‑contact roller structure for outstanding heavy radial load capacity. Inner ring and outer ring can be separated for convenient installation and disassembly. Covers N, NU, NJ, NF, NUP, RN, SL full‑complement, NN, NNU and FC series, widely used for motors, gearboxes, machine spindles and metallurgical rolling mill equipment. For complete technical introduction and detailed selection guidelines, please visit our cylindrical roller bearing hub page.
Quick Comparison of Main Designs
| Series | Key Feature | Load Type | Typical Application |
|---|---|---|---|
| N | Outer ring double ribs, inner ring without ribs, separable | Pure heavy radial load | General gearbox, transmission machinery |
| NU | Inner ring no ribs, permits axial displacement | Pure heavy radial load | Motor free end, gear reducer |
| NJ | Single rib on inner ring | Radial + one‑way axial load | Industrial gear unit, transmission |
| NF | Single rib on outer ring | Radial + one‑way axial load | General machinery, gearbox |
| NUP | With loose retaining ring, double‑way axial location | Radial + bidirectional axial load | Reducer, heavy industrial equipment |
| RN | Without outer ring, compact mounting dimension | Heavy radial load, compact space | Integrated gear housing, compact gearbox |
| SL Full‑Complement | No cage, maximum roller quantity, ultra‑high radial capacity | Extreme heavy radial load, low‑speed operation | Hoist, winch, heavy lifting machinery |
| NN / NNU | Double‑row, high rigidity | Extra‑heavy radial load | Machine tool spindle |
| FC / FCD | Four‑row heavy‑duty structure | Extreme radial load | Steel rolling mill |
Browse Sub‑Series
Outer ring double ribs, inner ring rib‑free separable design, mainly bear heavy radial load for general gearbox and transmission equipment.
Inner ring without ribs, allows axial displacement, widely used as free‑end bearing for motors and gear reducers.
Single rib on inner ring, capable of limited one‑direction axial load, popular for general industrial gear units.
Single rib on outer ring, accept moderate radial load plus one‑way axial force for transmission equipment.
Equipped with loose retaining ring, fixes shaft axial position in two directions for reducer and heavy machinery.
No outer ring structure, save installation space, fit compact integrated gearbox and limited‑space mechanical assemblies.
Cage‑less full complement rollers, maximum radial load capacity for low‑speed heavy‑load lifting and winch equipment.
High‑rigidity double‑row structure, precision grade available for machine tool main spindle applications.
Heavy‑duty four‑row cylindrical mill bearings for steel plant backup roll working conditions.
