SS-SA205G Stainless Steel Insert (SS1225-25ECG) OH/Groove

The SS-SA205G is a 25mm bore stainless steel insert bearing from Arrow Engineering’s SA Series, built for environments where standard chrome-steel bearings would corrode. It features a wide inner ring and eccentric locking collar, with a 52mm outside diameter.

A wide inner ring insert secured by a self-tightening eccentric locking collar rather than set screws — ideal for uni-directional drives and applications where vibration could back off a set screw.

• Bore: 25mm
• Material: corrosion-resistant stainless steel construction (typically 440C grade for this size range)
• Locking method: eccentric locking collar
• Inner ring type: wide inner ring
• Spherical self-aligning outer race
• Designed as a drop-in replacement insert for SA205 housings, pillow blocks, flange units and take-up units
• Suited to washdown, food & beverage, marine, water treatment and other corrosive or wet-duty applications

Variant note: OH/Groove variant — adds an oil hole and lubrication groove on the locking collar side for easier relubrication.

Fits standard pillow block, 2-bolt flange, 3-bolt flange, 4-bolt flange and take-up housings sized for the SA205 insert family. Pre-greased and ready to install.
