The NTN UCS series insert bearing is a ball bearing with a spherical outer ring and a single row of balls, designed to seat in split plummer block housings or in housings that allow self-alignment. It is used in equipment where the shaft must be supported with a certain angular tolerance, such as conveyors, fans or agricultural machinery. MR Accesorios Industriales sells this line in Buenos Aires, Argentina, with more than 80 years of experience in bearings and power transmission.
The UCS series designation is read in parts. The letters UCS identify the insert type with a spherical outer ring. The numbers that follow indicate the bore diameter and the dimension series: for example, UCS212-204D1 corresponds to a bearing of the 212 series with a 2 1/4 inch bore, while UCS212D1 is the variant with a metric cylindrical bore of 60 mm. The suffix D1 indicates a specific sealing and lubrication design. In the examples UCS213-208D1 and UCS215D1 the same criterion is repeated: series number and bore size.
These inserts are used in equipment that requires an adjustable support that is easy to mount. In Argentina they are found in conveyor belts in grain plants, in machines for the food industry, in industrial fans and in agricultural implements. They are also used in centrifugal pumps and in transmission shafts where the split plummer block housing makes maintenance easier without disassembling the assembly. The combination with split housings allows correcting misalignments caused by mounting or by the structure.
To select the correct insert, you must define the shaft diameter, the type of load and the environmental conditions. Sealing is key: in dusty or humid environments, a design with a more protective seal is advisable. Factory lubrication can be complemented with periodic greasing according to the duty cycle. During mounting, check that the outer ring seats well in the housing and that the shaft enters without forcing; careful alignment extends the service life of the bearing and prevents overloads on the rollers or balls.
UCS series insert bearings are interchangeable between brands according to the dimension standard. If the customer brings the part number of another brand, we can indicate the compatible equivalent. At MR Accesorios Industriales we quote the exact part number or size you need: write to us on WhatsApp with the model and we will reply shortly.

Frequently Asked Questions
- What does the D1 suffix mean in an NTN insert bearing?
- The D1 suffix indicates a specific design and sealing variant within the series. It does not change the main mounting dimensions, but it may vary the type of seal or the factory lubrication. To confirm the exact version, send us the complete part number.
- How do I choose between an insert with a metric bore and one in inches?
- It depends on the shaft diameter. If the shaft is in millimeters, choose the variant with a metric bore; if it is in inches, the designation with a hyphen and fraction. Measure the shaft with a caliper and send us the measurement so we can quote the corresponding part number.
- Can this insert bearing be used in split plummer block housings of other brands?
- Yes, as long as the housing has the same seating dimensions. The UCS series follows interchangeability standards, so it can be mounted in compatible housings. If you have doubts, send us a photo or the housing part number and we will advise you.
