NSK UELC series cartridge mounted bearings are units that combine an insert bearing and its housing in a single assembly. This type includes part numbers such as UELC204-012D1W3, UELC308-109D1W3 or UELC320-315D1W3, with different sizes and variants. Each part number has its own dimensions, so the complete designation is required.

The cartridge unit is a compact way to support a shaft: the insert bearing is already housed in its body, ready to be fixed to the machine structure. It avoids combining separate parts and simplifies assembly and replacement, which is practical in equipment with several identical support points.

In the designation, UELC identifies the cartridge format, the number that follows (204, 305, 320) indicates the unit size and the D1W3 suffix is part of the part number. Many part numbers also include a three-digit number after the hyphen, such as -012 or -315, which changes from one part number to another and must not be omitted. Others, such as UELC310D1W3, do not include it: they are different part numbers.

Since the numbering varies widely within the type, dimensions are not the same for all part numbers. The shaft diameter, body dimensions and mounting arrangement depend on each part number. Before ordering, compare these data with your shaft and mounting location, or send us the part number and we will verify it together.

During installation, check that the shaft is clean, free of burrs and wear, and that the cartridge support surface is flat and aligned with the shaft. Fix the unit evenly and check that it rotates without hard spots. Follow the manufacturer's instructions for shaft mounting and lubrication maintenance.
