The NTN AR2 series is a ball insert bearing built with an extended inner ring, made to sit in split plummer block housings or pillow blocks. It suits shafts that turn and need straightforward support and alignment, for example on conveyors, fans and farm equipment. MR Industrial Accessories LLC supplies this line to customers in the United States, Canada, Mexico and South America.
Reading the code helps you pick the right insert. The letters AR come first, then a three-digit number giving the insert size: AR201, AR202 and AR203 step up in inner diameter. A hyphenated numeric suffix can follow, as in AR201-008 or AR202-009, and it marks sealing variants or differences in outer ring dimensions. That suffix is what lets you match the exact version your equipment calls for.
These inserts show up on belt conveyors, mixers, screens, grinding equipment and ventilation systems, and in food industry machines where assembly and disassembly need to be quick. As compact units they keep maintenance work simple and cut downtime on lines that run continuously.
Selection comes down to shaft diameter, load type and the conditions around the bearing. Dust or moisture calls for a variant with heavier sealing. The insert goes onto the shaft with a proper fit, then locks to the housing through the set screws on the outer ring. Aligning the housing and lubricating to suit the duty cycle both matter for avoiding early wear.
AR2 series inserts can be swapped with other brands that use the same dimensional nomenclature. Bring a code from another maker and the team will point out the equivalent. Quoting from shaft and housing dimensions is also possible. What makes the swap work is standardized dimensions, not the code printed on the part.

Frequently asked questions
- What does the suffix in a code like AR201-008 tell me?
- Everything after the hyphen points to a variant of the same basic size, whether that is a sealing type, a special tolerance or a specific outer ring dimension. Send the code and the team will explain what sets that version apart.
- How do I decide between an AR201 and an AR202 insert bearing?
- Inner diameter and outer dimensions are what separate them, with the AR201 the smaller of the two. Measure the shaft diameter and check the housing bore. If anything is unclear, send the measurements and the matching code will be confirmed.
- Can NTN AR2 series insert bearings replace other brands?
- Yes, when the standardized dimensions line up. Inner diameter, outer diameter and width are what determine interchangeability, not the commercial code. Send a code from another brand and the NTN equivalent or closest alternative will be quoted.
