Overview
The 316 stainless steel 2-bolt oval flange pillow block bearing housing is a precision-engineered mounted bearing unit for industrial automation, motion control, and mechanical power transmission systems. 2-Bolt Oval Flange Bearings are equipped with a combination of a chrome steel set screw insert bearing with a housing of an oval cast iron 2-Bolt Flange. When specified in 316 stainless steel, this unit delivers superior corrosion resistance—ideal for food processing, chemical plants, washdown environments, and offshore applications where standard cast iron housings fail.
Key Features
- 316 Stainless Steel Housing: Corrosion resistant housing options include cast iron, stainless steel, thermoplastic, and nickel plating. The 316 grade provides exceptional resistance to saltwater, acids, and aggressive chemical exposure.
- 2-Bolt Oval Flange Design: Oval Units provide more mounting options and allow for some longitudinal adjustment. Facilitates quick, secure attachment to machine frames with minimal footprint.
- Removable Insert Bearing: The inserts can be removed from the housing for future replacement if required. Simplifies maintenance and bearing swaps without unbolting the entire housing.
- Dual Set Screw Lock: This specific bearing insert has two grub screws to allow tightening against the shaft once fitted. Prevents shaft slippage during operation.
- Industrial Duty: This type of bearing is intended primarily to reduce friction and permit free movement of turning parts. They are best suited for moderate loads and low speeds.
