The LINK-BELT ER-K series insert bearing is a single-row bearing with an extended inner ring, designed to be mounted in split plummer block housings, wall units or pillow blocks. It is used where the shaft rotates and a simple-to-mount unit is required, with good radial load capacity and the ability to lock the inner ring to the shaft. It is a common solution in power transmission and conveying equipment operating with dust, moisture or moderate vibration.

The ER-K series designation is read in parts: the letters ER identify the family of insert bearings with extended inner ring and the final letters indicate sealing or locking variants. In the example ER20SK, the central number corresponds to the shaft diameter and the suffix SK indicates a version with a locking ring. To choose correctly, take the complete part number of the insert and that of the housing where it is mounted, because both define interchangeability.

These inserts appear in belt conveyors, bucket elevators, mixers, screens, fans and packaging lines. In the Argentine market they are found in food plants, cement plants, meat processing plants, aggregate plants and agro-industrial facilities, where equipment runs for many hours and maintenance is done during scheduled shutdowns. They are also used in continuous process machines, where a bearing failure stops the entire line.

To select the insert, verify the shaft diameter and tolerance, the locking type (set screw, eccentric or adapter) and the sealing required by the environment. In dusty or wet applications, a contact seal is advisable; at high temperatures, a suitable grease and matching internal clearance. When mounting, align the housing, avoid striking the outer ring and lubricate according to the operating regime. Misalignment shortens insert life more than any other factor.

Interchangeability between brands is defined by the insert dimensions: shaft diameter, outer diameter, width and locking type. An insert from another brand with the same dimensions can replace the original, but the sealing and inner ring shape must be verified. If the housing is from another line, it is advisable to request a quote for the complete assembly. At MR Accesorios Industriales we will indicate the compatible alternative with the part number you provide.

To request a quote for your LINK-BELT ER-K series insert bearing, send us the complete insert part number on WhatsApp and, if possible, a photo of the housing or shaft. With that data we will quote you promptly and indicate the compatible alternative if needed. MR Accesorios Industriales supplies the LINK-BELT brand and manufactures split plummer block housings, ANSI chains and pulleys to complete the assembly.
