The LINK-BELT 300 series insert bearing is a single-row bearing with an extended inner ring, intended for mounting in split plummer block housings and take-up frames. It handles combined moderate radial and axial loads in equipment where the shaft rotates, such as belt conveyors, elevators and mixers.
Reading the 300 series code is straightforward: the prefix AG, a three-digit number and the suffix L. That number is a size identifier within the family, not a diameter, and it corresponds to a specific shaft size. For example, AG319L, AG323L and AG327L are three different sizes in the same series. The L suffix indicates the sealing and configuration variant. To select the right insert, provide the full code or the shaft measurement.
These inserts are commonly installed in split plummer block housings, take-up frames and split housings across food processing, cement, aggregates and water treatment operations. Typical applications include belt conveyors, bucket elevators, horizontal mixers and milling equipment. Because the insert and split housing work together, the bearing can be replaced without removing the shaft, which matters on continuous production lines where downtime is costly.
Selection depends on shaft diameter, load type and operating environment. The insert's sealing determines its resistance to dust, water or frequent washdowns. Use the lubrication specified for the working temperature, and align the housing with the shaft during mounting to prevent lateral stresses. Proper tightening of housing bolts and the use of suitable tools help extend the service life of the assembly.
300 series insert bearings are offered by several manufacturers, and equivalences are based on shaft diameter, inner ring width and locking type. A similar code alone is not enough; those critical dimensions must be compared. If you are replacing an insert from another brand, send the old code and the shaft measurement, and we will identify the compatible option within the LINK-BELT line.
MR Industrial Accessories LLC supplies the LINK-BELT line and understands these selection criteria. If you have the code AG319L, AG323L or any other in the series, contact us via WhatsApp or email for a quote. We can also help you pair the insert with the appropriate split plummer block housing.

Frequently asked questions
- How do I determine which 300 series insert I need?
- You need the shaft diameter and the housing type. With that information and the old part code, if available, we can identify the equivalent LINK-BELT insert. If not, send a photo and shaft measurements via WhatsApp.
- Are LINK-BELT 300 series inserts interchangeable with other brands?
- 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 on the code alone; compare those dimensions 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.
