The INA GRA-NPP-B Y-bearing insert is a sealed bearing unit designed for direct mounting in split pillow block or plummer block housings. It features an extended inner ring and is suited for equipment requiring smooth rotation and protection from contamination. MR Industrial Accessories LLC supplies this series to customers across the US, Canada, Mexico and South America.
The part number structure provides key information. The GRA prefix identifies the Y-bearing family with an extended inner ring. The numeric portion, such as GRA010, GRA012 or GRA104-206, indicates bore diameter and locking variant. The NPP suffix denotes double sealing, while B refers to the outer ring design. Additional suffixes like AS2/V specify seal type and factory lubrication. Always reference the complete designation when requesting a quote.
These inserts are used in conveyors, fans, mixers, screens and agricultural equipment. They are common in food processing, cement, aggregate and water treatment facilities where dust or moisture is present. Because the insert can be replaced without changing the housing, they are also practical for equipment that undergoes frequent repairs.
For selection, first confirm shaft diameter and locking method—set screws or eccentric collar. The double NPP seals retain grease and block contaminants. During installation, align the housing, tighten locking screws properly, and ensure the inner ring is secure on the shaft. Relubricate only if the bearing is designed for it.
When seeking an equivalent, match bore diameter, width, seal type and locking system rather than the complete part number. Inserts from different brands may interchange if dimensions and locking match, but suffixes and internal clearance can vary. Send the original part number or a photo for verification.

Frequently asked questions
- What does the NPP suffix mean on an INA Y-bearing?
- NPP indicates double sealing, one on each side. This protects the internal grease and blocks dust, chips and splashes, making it suitable for contaminated environments.
- How do I choose a replacement Y-bearing insert?
- Compare bore diameter, width, shaft locking type and sealing. The complete part number is helpful, but dimensional and locking match are critical. Provide the original part number or photo for assistance.
- Can an INA insert be mounted in a housing from another brand?
- Yes, if the insert and housing dimensions match. Housings follow standardized dimensions, so an insert from one brand can fit another brand's housing when outer diameter and width align.
