The LINK-BELT ER-K series is a single-row insert bearing with an extended inner ring. It mounts into split plummer block housings, wall units or pillow blocks, and is intended for rotating shafts where a straightforward installation and solid radial load support are needed. The inner ring can be locked to the shaft, which makes this series a practical choice for power transmission and conveying equipment exposed to dust, moisture or moderate vibration.

Reading the ER-K code helps with identification. The letters ER point to the extended-inner-ring insert family, while the closing letters show the sealing or locking version. In a reference such as ER20SK, the number in the middle is the shaft diameter and SK signals a locking-ring design. For a correct match, keep both the insert part number and the housing part number on hand, since the two together determine interchangeability.

Typical equipment includes belt conveyors, bucket elevators, mixers, screens, fans and packaging lines. In food processing, cement, meat processing, aggregate and agro-industrial plants, these inserts run for long hours and are serviced during planned shutdowns. They also appear in continuous-process machinery, where a bearing failure can bring the whole line to a stop.

When selecting an insert, confirm the shaft diameter and tolerance, the locking method (set screw, eccentric or adapter) and the sealing level the environment demands. Dusty or wet conditions call for a contact seal; high temperatures require a suitable grease and matching internal clearance. During installation, align the housing, avoid hammering on the outer ring and lubricate according to the operating regime. Misalignment is the most common cause of shortened insert life.

Interchangeability across brands depends on insert dimensions: shaft diameter, outer diameter, width and locking type. An insert from another manufacturer with the same dimensions can serve as a replacement, but the seal and inner ring shape should be checked. If the housing comes from a different line, it is best to request a quote for the complete assembly. Share the part number you have and we will point you to the compatible alternative.
