The INA RAL-NPP Y-bearing is an insert with an extended inner ring and the NPP double-sided seal, meant to sit inside split plummer blocks, flanged housings or take-up units. It suits transmission and conveying duty where mounting is quick and contamination is a concern. MR Industrial Accessories LLC supplies this INA line and helps you match the part number to your application.

Reading the code helps you select correctly. RAL marks the series of inserts with extended inner ring and set screw locking. The digits that follow, as in RAL012-NPP, give the insert size. NPP covers the sealing arrangement: a labyrinth plus an elastomer lip seal on both sides, which keeps dust, water and particles away from the raceway and plays a large part in how long the insert lasts in tough conditions.

Once assembled into a split plummer block, flanged housing or take-up frame, these inserts become complete Y-bearing units. Typical duty includes belt conveyors, bucket elevators, mixers, mills, packaging lines and process equipment in food, chemical and aggregate plants, where washdown, dust and fast changeover all matter.

Selection starts with shaft diameter, housing style and operating conditions. NPP sealing handles moisture and dust well; where frequent washdowns occur, consider extra protection. At mounting, line up the housing, then tighten the set screws onto the shaft with the right wrench, never hammering the outer ring. Relubricate according to the duty cycle and verify clearance and alignment so parasitic loads do not appear.

RAL-NPP inserts can be swapped with other brands using the same dimensional and locking nomenclature, though seal design, inner ring tolerance or locking method may differ. Compare the full part number and the critical dimensions before substituting. If anything is unclear, send the number engraved on the bearing, or your shaft and housing measurements, and our team will help identify the equivalent.
