The LINK-BELT 300 series insert bearing is a single-row bearing with an extended inner ring, designed to be mounted in split plummer block housings and take-up frames. It is used in equipment where the shaft rotates and the load combines moderate radial and axial forces, such as belt conveyors, elevators and mixers. MR Accesorios Industriales supplies this line backed by more than 80 years in the industrial sector.
The 300 series designation is read with the prefix AG followed by a three-digit number and the suffix L. The number identifies the insert size within the series: it is not a diameter or a direct measurement, but a catalogue code that correlates with the shaft diameter. Thus, AG319L, AG323L and AG327L are three different sizes of the same family. The suffix L distinguishes the sealing and configuration variant of the insert. To choose the right one, send us the complete code or the shaft measurement.
These inserts are mounted in split plummer block housings, take-up frames and split housings used in food, cement, aggregates and water treatment plants. In Argentina they appear in belt conveyors, bucket elevators, horizontal mixers and milling equipment. The combination of insert and split housing allows the bearing to be replaced without dismantling the shaft, which is key in continuous production lines where every minute of downtime counts.
To select correctly, take into account the shaft diameter, the type of load and the environmental conditions. The insert's sealing defines whether it withstands dust, water or frequent washdowns. Lubrication must be the one indicated for the working temperature, and mounting requires aligning the housing with the shaft to avoid lateral stresses. Correct tightening of the housing bolts and the use of suitable tools extend the service life of the assembly.
300 series insert bearings are available from several brands, and equivalences between manufacturers are established by shaft diameter, inner ring width and type of locking. It is not enough for the code to be similar: those critical dimensions must be compared. If you need to replace an insert from another brand, send us the old code and the shaft measurement, and we will indicate the compatible alternative within the LINK-BELT line.
At MR Accesorios Industriales we work with the LINK-BELT line and know the criteria so that the correct insert reaches your plant. If you already have the code AG319L, AG323L or any other in the series, write to us on WhatsApp and we will quote it shortly. We can also advise you if you need to assemble the unit with the appropriate split plummer block housing.

Frequently Asked Questions
- How do I know which 300 series insert I need?
- You need the shaft diameter and the type of housing where it is mounted. With that data and the code of the old part, if you have it, we will indicate the equivalent LINK-BELT insert. If not, send us a photo and the shaft measurements on WhatsApp.
- Are LINK-BELT 300 series inserts interchangeable with other brands?
- Yes, in many cases they can be replaced by inserts from other brands if the shaft diameter, inner ring width and locking system match. Do not rely only on the code: compare those measurements or consult us with the original code.
- What lubrication do these insert bearings require?
- They require general-purpose bearing grease, compatible with the equipment's working temperature. In humid environments or with frequent washdowns, a grease with higher water resistance is advisable. Follow the equipment manufacturer's recommendation and relubricate according to operating hours.
