NTN ARP-2S pillow block bearing

NTN ARP-2S belongs to pillow block bearing, part of our Bearing housings range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for ARP-2S and any equivalents.

An ARP unit is a ready-to-bolt support: a cast iron pillow block housing supplied with a ball or roller insert bearing, aligned and sealed before it leaves the factory. It suits transmission shafts on equipment that has to go back into service quickly and be replaced without special tooling. MR Industrial Accessories supplies the NTN line and quotes on the exact part number you specify.

Read the ARP code in two parts. The letters point to the pillow block housing family that takes an insert bearing; the digits that follow give the shaft size the unit is machined for. Suffixes then tell you about sealing, mounting or how the housing is configured, so ARP-2S is simply an ARP unit carrying its own suffix. Pass along the complete number and that is the variant we quote.

Typical duty covers belt conveyors, sorting belts, mixers, extractors, bucket elevators and packaging lines, plus water treatment equipment, industrial ventilation and agricultural machinery. In food, chemical and aggregate plants the appeal is the same: the assembly arrives complete, the base is bolted down, the shaft goes in and the line runs. Dust, moisture and washdown are handled by the sealing choice rather than by the housing itself.

Selection starts with two things: shaft diameter and insert mounting type. Units come with set screws, with an eccentric locking collar or with a taper adapter, and each calls for a different fitting procedure. Sealing sets the working environment, with labyrinth suitable for coarse dust and a contact lip seal for moisture or liquids. When mounting, seat the base on a flat, rigid surface, tighten bolts in a cross pattern and confirm shaft alignment before the drive is started. Follow the rotation regime for lubrication and check radial clearance where loads alternate.

Mounted units swap between brands by shaft number and housing configuration, not by manufacturer code. Where another brand is already fitted, the figures that matter are shaft diameter, center distance between base holes, height to center and insert mounting type. Give us those and we identify the matching NTN unit. If the old part carries no identification, a photo plus the shaft measurement is usually enough.

If you have the ARP part number, the equipment model or just the shaft size, send it over by WhatsApp or email and the team will come back with a quote and, where useful, an equivalent option. Bearings, housings, chains and pulleys sit in the same catalog, so a replacement can often be settled in one inquiry.
