The MRC Marathon series tapped base pillow block is made with a composite housing and ZMaRC coated insert for resistance to corrosion. The solid one-piece housing with ball bearing insert is built for maximum strength and rigidity and allows installation where guided shafts are close together. The contact-and-flinger seals retain lubricant, protect against contamination, and are non-relubricatable. A non-expansion-type bearing with setscrew locking collar provides a secure attachment to a guided shaft. The pillow block composite housing resists citric acids and cooking fats, making it suitable for use in food and beverage processing applications.

Mounted bearings combine a bearing mounted inside a housing unit. The bearing housing replaces the need for a casting or weldment to position the bearing securely for reliable operation, and its design determines the type of insert bearing. Insert bearings use rolling elements (ball, cylindrical, spherical, barrel, needle, spindled, or tapered) to maintain the separation between moving parts to reduce rotational friction, and to support radial and axial loads. Available in a variety of materials and mounting configurations, mounted bearings can be one- or two-piece, they can have an extended inner ring and locking device, and they can have seals and end caps that retain lubrication and protect the working parts of the bearing from environmental debris. Mounted bearings support shafts in a variety of mounting configurations (flange block, hanger, pillow block, and take-up block), and are used in a range of applications from light duty shaft guidance on conveyors to road building equipment and crushers.

MRC Bearing Services manufactures ball bearings for automotive, food and beverage, energy, aerospace, and other industrial and commercial applications. The company is headquartered in Jamestown, NY.
