The NTN AS series insert bearing is a ball bearing with an extended inner ring, designed to be mounted in split plummer block housings and bearing units. It is used in equipment that requires smooth rotation with simple alignment, such as conveyor belts, fans and agricultural machinery. MR Accesorios Industriales sells this line in Buenos Aires, Argentina, and helps you identify the exact size from the part number stamped on the part.

The AS series designation is read in blocks: the first number indicates the type of inner ring locking, the letters AS correspond to the series, and the number that follows —08, 09, 11, 14— is linked to the shaft diameter. Suffixes such as 1.5/32, 1.1/2 or 2.1/32 express the bore in inches and fractions, and the final letter D indicates sealing or insert configuration variants. That is why, when ordering a 1AS08-1.5/32D1 or a 3AS14-2D1, it is best to provide the full part number: each block changes the fit on the shaft.

These inserts are mounted in split plummer block housings and bearing units found in food plants, material handling, mills, water treatment plants and agricultural equipment. In Argentina they are common in conveyor belts, bucket elevators, mixers and industrial fans. The insert plus split plummer block housing combination allows the assembly to be removed without dismantling the shaft, which is very practical in maintenance of lines that cannot stop for long.

To choose well, first look at the shaft diameter and the type of inner ring locking: there are types with set screws, with an eccentric ring or with an adapter sleeve. Then check the sealing: an insert with a contact seal protects better against dust and moisture than an open one. During installation, make sure the housing sits flat and the shaft is aligned with the drive; poor alignment shortens bearing life. Factory lubrication is usually enough for several seasons, but in dirty environments relubrication should be scheduled.

As for equivalents, NTN AS series inserts can replace other extended inner ring insert lines with the same shaft and housing dimensions. Interchangeability is not automatic: bore, overall width, set screw location and sealing type must be compared. If you have another brand's part number, send it along with the shaft size and housing dimensions, and we'll tell you the compatible NTN alternative or the one that best fits your equipment.

If you need to replace an insert for a bearing unit, send the full part number on WhatsApp to MR Accesorios Industriales: 1AS08-1.5/32D1, 2AS09-1.1/4D1 or whichever you have. With that data and a photo of the part we'll quote the exact reference and get it to you shortly. We can also advise you if the part number is worn off and you only have the shaft and housing measurements.

Frequently Asked Questions

How do I identify the shaft diameter on an AS series insert?
The number after AS —08, 09, 11, 14— relates to the shaft diameter, and the suffix with a fraction, such as 1.1/2 or 2.1/32, confirms it in inches. If you have the full part number, send it on WhatsApp and we'll quote the exact size.
What is the difference between an insert with set screws and one with an eccentric ring?
The way the inner ring is locked to the shaft changes: set screws lock with screws, while the eccentric type uses a ring that turns and tightens. To choose, look at how the original insert was mounted and send us that data when requesting a quote.
Can I replace an insert from another brand with an NTN AS series one?
Yes, if the shaft diameter, width, locking location and sealing type match. It is not enough for the shaft size to be the same. Send us the old part's number or the housing measurements and we'll tell you the corresponding NTN equivalent.
