Product Description

This Kilian “No Rust” ball bearing flange unit with four bolt holes, a grease fitting, and a setscrew lock is designed for mounting onto bearing surfaces perpendicular to the shaft axis. This ready-to-mount unit has a housing made of a thermoplastic material that resists rust and corrosion from heavy washdown environments and harsh chemicals, such as acids and solvents. It is equipped with a fitting on the outer surface for reapplying lubricant, and a solid base to reduce the risk of contamination through gaps in the material. The ball bearing insert in the housing is made of 330 stainless steel for resistance to corrosion from chemicals and frequent washdowns in food processing and packaging applications. It supports moderate speeds and moderate radial, thrust, and combined loads. Its wide inner ring provides increased support to the shaft. This bearing unit operates under continuous temperatures of up to 250 degrees Fahrenheit (121 degrees Celsius). The bearing locks onto the shaft with two setscrews for a three-point contact hold. This lock type minimizes ring distortion and vibration and is suitable for low to moderate speed applications where the shaft rotates in a single or reversing direction. Flanged bearing units are suitable for use in industrial and commercial applications including conveyors, fans and blowers, construction machinery, and processing equipment, among many others.

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.

Kilian Bearings manufactures precision-machined custom bearings and assemblies. The company, founded in 1922 and headquartered in Syracuse, NY, meets International Organization for Standardization (ISO)/TS 16949:2002 and ISO 9001:2000 standards.
