Cylindrical roller bearings

These bearings are highly rigid and can absorb high radial forces. Cage versions accept higher speeds than full complement versions. Equipped with separable rings, dismounting and withdrawal re simple, even when tight clearances are necessary.

Standard range: NN and NNU with solid cage
Series: 3900, 3000, 3100, 4800, 4900, 4000
Type NN and NNU bearings: also available with a tapered bore
Types of applications: machine tools or heavy industry

4 ROWS CYLINDRICAL BEARINGS WITH CAGE (Type 4R)

Bearings with solid cage, also available in large dimensions (d. ≤ 1200 mm)
Possible variants

  • Case hardened or carbo-nitrided steel for improved resistance
  • Lubrication holes

2 ROWS CYLINDRICAL FULL COMPLEMENT (Type SL)

Range suitable for high radial loads and/or to meet the need for excellent rigidity.
Types SL01, SL02 and SL04 can absorb axial forces in both directions in addition to substantial radial forces
Possible variants

  • Grooves for snap rings in the outer ring (series SL04) for pulley applications, for example
  • Double sealing (LL)

CROSSED ROLLER BEARINGS (Type QR)

Suitable for high rotation precision combined with high forces
Types of applications: robotics, indexing tables
