Product description of TIMKEN Bearing NNU49/560MAW33

TIMKEN Bearing NNU49/560MAW33, It divided into Category: TIMKEN Bearing > Cylindrical Roller Bearings > Cylindrical Roller Radial Bearings - Two-Row.

Timken® two-row, or double-row, cylindrical bearings offer added radial capacity and are interchangeable. Dimensions and diameters under the rollers (NNU style) and over the rollers (NN style) meet ISO standards.

Two-row, or double-row, cylindrical bearings are designed for additional strength in carrying radial loads. These bearing types are interchangeable so the dimensions and diameter under the rollers (NNU style) and diameter over the rollers (NN style) are held to an ISO/DIN standard. Interchangeability is designed for the ring without the rollers to allow interchange with competitor inner rings.

Size range: 80 mm to 2000 mm OD

Design Attributes
Designed to ISO/DIN specified interchangeable dimensions where available.
Sold as complete assembly.
