The SS-CSB204 is a 20mm bore stainless steel insert bearing from Arrow Engineering’s CSB Series, built for environments where standard chrome-steel bearings would corrode. It features a flat back / flat outer and set screw locking, with a 47mm outside diameter.
A flat-back, flat-outer-ring insert bearing designed for panel and flange-plate mounting rather than a spherical self-aligning housing.
- Bore: 20mm
- Material: corrosion-resistant stainless steel construction
- Locking method: set screw locking
- Inner ring type: flat back / flat outer
- Flat-back, flat outer ring (not spherical/self-aligning) — for panel or flange-plate mounting
- Designed as a drop-in replacement insert for CSB204 housings, pillow blocks, flange units and take-up units
- Suited to washdown, food & beverage, marine, water treatment and other corrosive or wet-duty applications
Fits standard pillow block, 2-bolt flange, 3-bolt flange, 4-bolt flange and take-up housings sized for the CSB204 insert family. Pre-greased and ready to install.
