The NSK AS series insert bearing is a sealed unit with an extended inner ring, made to sit directly on a shaft and inside a split or solid pillow block. Conveyors, fans, pumps and farm equipment rely on this design for smooth running and protection from contaminants. Installation and removal are straightforward, and relubrication in service is possible on many models.
Reading the AS code helps you order the right part. The letters AS mark the family: insert bearings with an extended, sealed inner ring. The digits that follow, such as AS201, AS202, AS203 or AS204, set the shaft diameter and the related dimensions. A numeric suffix after a hyphen—AS201-008, AS202-009, AS202-010—points to a special bore size, usually in inches or with a non-standard tolerance. Always confirm the full code against both shaft and housing.
These insert bearings appear in belt conveyors, bucket elevators, mixers, mills, pumps and ventilation systems. Seeders and harvesters also use them, where dust and weather are constant. They handle moderate radial and axial loads, which suits equipment that runs continuously in tough conditions.
For selection, start with shaft diameter, housing type and operating conditions. Sealing matters: double-lip seals give better protection against dust and moisture. Correct lubrication extends service life, and many inserts accept grease through a fitting. Align shaft and housing during assembly to avoid extra loads. At high speeds, check that internal clearance is suitable.
Cross-brand equivalents exist, but dimensions and suffixes can differ slightly between makers. When replacing another brand, compare bore diameter, outer diameter and width first. If you have the original part number, send it and we will point you to the alternative that fits best.
