NU2205-E-TVP3 Single Row Cylindrical Roller Bearing 25x52x18mm Polyamide Cage

1. Product Overview

NU2205-E-TVP3 is single row NU-type cylindrical roller bearing, overall dimension 25×52×18mm. E stands for optimized roller geometry for higher load capacity; TVP3 means high-strength injection molded polyamide cage. Outer ring with double ribs, inner ring rib-free, enabling bidirectional axial floating displacement to absorb shaft thermal expansion. Separable inner and outer rings simplify installation and disassembly. Open design supports regular re-lubrication, suitable for medium-high speed heavy radial load working conditions. Widely applied to electric motors, small gearboxes, machine tool spindles, fan pumps and light construction machinery transmission shafts.
