NSK Bearing housings

The UCP2 pillow block with NSK insert bearing is a mounted unit that combines a cast iron housing with a self-aligning, sealed insert bearing. It is used to support rotating shafts in transmission, conveying and process equipment, where a compact and easy-to-mount solution is needed. MR Accesorios Industriales sells this line in Buenos Aires, Argentina, and advises you on choosing the correct size according to your shaft and your application.

The UCP2 designation reads as follows: UCP indicates a pillow block unit with insert bearing; the 2 corresponds to the size series, which in this case is series 2, medium section. Examples such as UCP201D1, UCP202-009D1 or UCP204-012D1 show that after the series number a numeric suffix preceded by a hyphen may appear, which identifies the shaft diameter in inches when it is not metric. The D1 suffix indicates a design variant of the insert, usually linked to the type of sealing and factory lubrication. The UCP3 series shares the logic but with larger sizes.

These pillow blocks are seen in belt conveyors, bucket elevators, mixers, fans, centrifugal pumps and packaging lines. In Argentina they are common in food plants, cement plants, tanneries and metalworking shops, where the environment may have dust, humidity or frequent washdowns. The cast iron housing with a flat base allows it to be fastened to sheet metal structures or profiles, and the self-aligning insert absorbs small shaft misalignments, which simplifies mounting and reduces maintenance.

To select well, take into account the shaft diameter, the type of load (radial, axial or combined) and the environmental conditions. The insert sealing defines the protection: for environments with coarse dust or water, a more robust seal is advisable. Lubrication comes from the factory and in service it is replenished according to the duty cycle. When mounting, rest the base on a flat, clean surface, tighten the fastening screws and check the alignment of the shaft with the opposite pillow block. Poor alignment accelerates wear of the seal and the insert.

UCP2 and UCP3 units from different brands are usually interchangeable in terms of main dimensions and shaft diameter, as long as the series standard is respected. If you bring the part number from another brand or an unidentified part, at MR Accesorios Industriales we will tell you the compatible equivalent. Interchangeability does not always extend to the type of sealing or the permissible load, so it is advisable to confirm those details before replacing.

The UCF housing with NSK insert bearing is an assembled 4-bolt flange unit that combines an insert bearing with a cast iron housing. It is used to support rotating shafts on flat structures, with fixed alignment and simple mounting using four bolts. It is a common solution in transmission, conveying and process equipment where robustness and ease of replacement are required. MR Accesorios Industriales sells this line in Buenos Aires, Argentina.

The designation of the UCF2 series is read in parts: UCF identifies the square 4-bolt flange housing, and the number that follows indicates the size of the insert bearing. For example, UCF201D1 and UCF202D1 correspond to sizes 201 and 202. The hyphenated suffixes, as in UCF201-008D1 or UCF204-012D1, indicate inch shaft diameter variants. The D1 ending distinguishes a construction variant within the series. Knowing these keys allows you to order the exact part number.

These housings are used in a wide variety of industries in Argentina: packaging lines, conveyor belts, mills, mixers, refrigeration equipment and water treatment plants, among others. Their 4-bolt flange allows them to be fastened to profiles, plates or beds with aligned holes. Being self-aligning units, they tolerate small misalignments and simplify field mounting. MR Accesorios Industriales sells them for replacement and new projects.

To select the correct housing, take into account the shaft diameter, the type of load and the environmental conditions. The sealing of the insert defines the protection against dust and moisture: choose the appropriate version if the equipment operates in dirty environments or with frequent washdowns. Factory lubrication can be replenished through the grease fitting if the insert includes one. During mounting, verify that the support surface is flat and that the bolts are tightened evenly to avoid deformation.

UCF housings are interchangeable between brands in terms of flange dimensions and shaft diameter, as long as the series standard is respected. If you bring the part number of another brand or an unidentified part, at MR we tell you the compatible equivalent. The NSK UCF2 series is manufactured under its own specifications, so it is advisable to confirm the complete part number when requesting a quote. Write to us on WhatsApp with the part number or the exact measurement and we will quote it promptly.

The UCFL2 flange housing with insert bearing is an assembled two-bolt flange unit that combines a cast housing with an insert bearing. It is used to support rotating shafts in power transmission equipment, where simple mounting and correct alignment are required. MR Accesorios Industriales sells this NSK line in Buenos Aires, Argentina, and quotes it on WhatsApp with the full part number.

The series designation is read in blocks: UCFL indicates a two-bolt flange housing with insert bearing, and the 2 that follows defines the size series. The suffixes order the rest: in UCFL201D1 the D1 ending identifies the design variant of the unit; in UCFL201-008D1 the 008 block corresponds to the shaft diameter in inches, while in UCFL201D1 the shaft is expressed in millimeters. Thus, UCFL202-010D1 and UCFL203D1 share the series but change the shaft diameter. Send us the full part number and we will quote it.

These housings appear in belt and roller conveyors, packaging lines, mixers, fans, centrifugal pumps and industrial washing equipment. In Argentina they are seen in food plants, meat processing plants, tanneries, water treatment plants and metalworking shops, always on shafts that rotate at moderate speeds and with combined radial and axial loads. The two-bolt flange allows mounting on folded sheet metal, profiles or concrete beds with simple alignment.

To choose correctly, take into account the shaft diameter, the insert locking type (set screw or eccentric) and the sealing: variants with a contact seal retain grease better and block the entry of dust and water. During mounting, rest the flange on a flat, clean surface, tighten the bolts in a cross pattern and check that the shaft is aligned with the drive equipment. The insert is lubricated through the housing nipple; it is advisable to check it according to service hours and the environment.

As for equivalents, two-bolt flange housings with insert bearing are interchangeable between brands by series and shaft diameter: a UCFL2 from another company can replace an NSK if the series, diameter and locking type match. The differences are usually in the sealing, internal clearance and surface treatment of the housing. If you bring an unidentified part or another brand's part number, at MR Accesorios Industriales we will indicate the compatible alternative.

To move forward, send us the full part number on WhatsApp —for example UCFL204-012D1— or the shaft size and the flange type you need. We will quote the part number or the exact size and reply shortly. If you are looking for a variant you do not see, write to us with the model and we will handle it.
