NJ 228 ECP Single Row Cylindrical Roller Bearing 140x250x42 mm

Cylindrical Roller Bearing, NJ 228 ECP, 140x250x42 mm, Steel Cage, Single Row, No Seal, No Separable; No Snap Ring, Relubricatable, C0.

Single row cylindrical roller bearings are designed to accommodate high radial loads in combination with high speeds. Having two integral flanges on the outer ring and no flanges on the inner ring, NJ design bearings can accommodate axial displacement in both directions. An important feature is the separable design, which facilitates mounting and enables the bearing components to be interchanged.

EC: Optimized Internal Design Incorporating More And/Or Larger Rollers And With Modified Roller/End Flange Contact.

P: Injection Moulded Cage Of Glass Fibre Reinforced Polyamide 6,6, Roller Centered
