Dayton 2X897 pillow block bearing, steel housing, 1/2 in bore, bolt-through mount

Dayton

Dayton 2X897 Pillow Block Bearing 1/2" Bore

SKU CH-BT2W-CH93D

Pillow block bearing with a 1/2 in bore, double-sealed alloy-steel insert and steel housing rated to 6,000 RPM

  • 1/2 in bore fits standard shafts
  • Double sealed closure keeps contaminants out
  • Steel housing withstands heavy loads
  • Operates from -30 °F to 200 °F
  • Rated for 6,000 RPM maximum speed

Application Fit

The Dayton 2X897 pillow block bearing supports a 1/2 inch cylindrical shaft in light-duty power-transmission systems. It suits maintenance crews and OEM assemblers who need a ready-to-mount housed unit with a two-bolt footprint. Buyers who require a larger bore, a four-bolt base, or a split housing for mid-shaft installation cannot use this unit.

Sustained Operation

Double-sealed construction retains the factory NGLI #2 equivalent grease while excluding contaminants during continuous runs up to 6,000 RPM. Alloy-steel balls and races operate reliably between -30 and 200 degrees Fahrenheit. The steel housing and 15/16 inch center height maintain alignment under steady radial loads without the overheating risk seen in high-speed bursts.

Installation Notes

Two bolt-through holes spaced 3 3/16 inches centre-to-centre accept standard fasteners for quick mounting on a prepared surface. The 1.875 inch overall height and low 0.11 inch base height leave minimal shimming room, so the mounting surface must be flat. Misalignment or over-tightening the mounting bolts are the most common causes of premature noise or seal damage.

The bearing is rated for a maximum operating temperature of 200 degrees Fahrenheit and a minimum of -30 degrees Fahrenheit, making it suitable for continuous running within that range.

What mounting hardware and shaft size are required to install the 2X897 bearing?

The unit needs a 1/2 inch cylindrical shaft and two bolt-through mounting holes spaced 3 3/16 inches center-to-center for secure installation.

Will the 2X897 bearing fit existing equipment that uses a standard 1/2 inch bore pillow block?

Yes, the 1/2 inch bore diameter and 15/16 inch center height match common pillow block dimensions, allowing direct replacement on compatible shafts and mounting surfaces.
