MA620748 REXNORD Pillow Block Aligning Roller Bearing

The Rexnord MA620748 is a premium-quality, self-aligning pillow block roller bearing designed to deliver superior performance and reliability in heavy-duty industrial applications. This bearing features a large, single-row, deep-groove ball bearing design, which allows it to accommodate substantial radial loads while maintaining precise alignment between coupled rotating shafts.

The self-aligning design of the MA620748 is achieved through the use of tapered roller bearings in the outer raceway. These tapered rollers can adjust to misalignments between the shafts, reducing the stress on the bearing and extending its operational life. The inner raceway is composed of a high-quality, smooth-running, chrome steel ball bearing.

The MA620748 comes in a pillow block housing, which provides ample space for easy installation and maintenance. The housing is made from robust, cast iron material, ensuring durability and resistance to harsh environments. It is also equipped with a grooved, double-sealed design that provides effective protection against contaminants, such as water, dust, and lubricants, for extended bearing life.

The bearing's dimensions are 2-7/16 inches in width and is suitable for shaft sizes ranging from 1.49 to 1.75 inches (38 to 44.45 mm). The maximum radial load capacity is 25,000 lbs (111,111 N), making it an excellent choice for heavy-duty applications. The MA620748 also offers a high speed rating (C4), enabling it to operate efficiently at higher rotational speeds.

The Rexnord MA620748 comes with a precision-machined bore and a high-quality, pre-lubricated grease to ensure smooth, reliable operation right out of the box. This self-aligning pillow block roller bearing is an essential component for various industries, including oil and gas, mining, power generation, and heavy machinery manufacturing, where high loads, misalignment, and harsh environments are common.
