The SEALMASTER ER series insert bearing is a single-row bearing with an extended inner ring, designed to be mounted in split pillow blocks and wall units. It is used when the insert needs to be replaced without changing the housing, or to assemble new equipment with a split housing. MR Accesorios Industriales supplies this line with technical advice so you can choose the correct code for your application.
The ER series designation is read with the prefix ER and a number indicating the insert size: ER-8, ER-9, ER-10, ER-11, ER-12, ER-14, ER-15 and ER-16 are some of the available codes. That number is not a diameter or a direct measurement: it is the reference the manufacturer assigns to the assembly according to its size. Therefore, to order the correct replacement, provide the complete code shown on the equipment or on the old part.
These inserts are used in conveyors, belts, elevators, mills, mixers and process equipment in food, chemical and materials plants. In Argentina they are commonly found in packaging lines, bucket elevators and grain handling systems, where the split pillow block allows the shaft to be removed without disassembling the entire machine. The ER series covers a size range from small equipment to medium-load applications.
To select correctly, consider the type of sealing the environment requires: if there is dust, water or frequent washdown, a more closed protection is advisable. Also check the internal clearance and lubrication type, because an insert that is poorly lubricated or has excessive clearance shortens bearing life. During installation, make sure the housing is aligned and the inner ring is properly secured to the shaft; misalignment generates loads the insert is not designed to withstand.
Insert bearings are available from several brands with their own nomenclatures. Interchangeability is not automatic: two codes may have the same shaft diameter but different width, sealing or locking system. Therefore, before replacing with another brand, compare the critical dimensions and mounting type. At MR we can indicate the compatible alternative if you send us the original code and a photo of the part.
If you need the SEALMASTER ER series insert, send us the exact code via WhatsApp (for example, ER-12) and the quantity. We will quote it promptly. If you cannot find the reference, write to us with the housing model or shaft dimensions and we will help you identify the part. MR Accesorios Industriales has more than 80 years supporting Argentine industry with power transmission components and bearings.

Frequently Asked Questions
- How do I know which ER code I need?
- The ER code identifies the insert size, not a direct diameter. The safest way is to read the number stamped on the old bearing or on the equipment nameplate. If you do not have it, send us the shaft and housing dimensions via WhatsApp and we will help you identify it.
- Can I change only the insert without changing the housing?
- Yes, that is one of the advantages of split pillow blocks: the housing is opened, the worn insert is removed and a new one is installed. Check that the housing is in good condition and that the new insert has the same housing dimensions.
- What is the difference between an ER insert bearing and a 62 series bearing?
- The ER insert has an extended inner ring and a shaft locking system designed to be mounted in split housings. The 62 series is a general-purpose deep groove ball bearing, mounted in cylindrical housings. They are not directly interchangeable.
