BUNTING BEARINGS

About BUNTING BEARINGS

Bunting Bearings is a manufacturer of plain bearings, bushings, and related components, with a product history that includes cast bronze and non-leaded metallic sleeve bearings. The company's catalog covers sleeve bearings, flanged bearings, thrust washers, and bar stock, serving applications where radial or oscillating loads must be supported with minimal maintenance. Bunting Bearings products are commonly specified in industrial machinery, conveyors, pumps, gearboxes, and material handling equipment. The sleeve bearings supplied by 3G Electric include general-purpose metallic and non-leaded metallic types, with bore sizes ranging from 5/16 in to 2-3/16 in and outside diameters from 1/2 in to 2-7/8 in. Lengths vary from 1 in to 4-1/2 in. Operating temperature ratings for the general-purpose bronze sleeve bearings reach from -450°F to 500°F, while the non-leaded metallic variant is rated from -40°F to 400°F. These bearings are intended for rotating or oscillating shaft applications, handling radial loads in continuous or intermittent duty. The non-leaded construction of certain models addresses requirements for reduced lead content in the bearing material. 3G Electric supplies Bunting Bearings sleeve bearings and bushings as part of its industrial equipment catalog, supporting procurement and maintenance teams with part-number-level identification and global logistics. The product range includes both individual pieces and multi-packs, such as 3-pack configurations for selected sizes. Technical buyers can reference manufacturer part numbers like EBCB243012, CB313532, CB354636, CB050808, CB303824, CB182224, CB202420, and CB162011 when specifying replacements or new installations. 3G Electric's role is to make these Bunting Bearings components available through a single sourcing channel, with the ability to quote and ship internationally. The bearings are suited for original equipment and aftermarket use in plants that require reliable shaft support with simple installation and no external lubrication in many cases. For engineers and maintenance managers, the key selection parameters are bore, outside diameter, length, and temperature rating, all of which are published for each Bunting Bearings sleeve bearing in the 3G Electric catalog. This allows direct cross-referencing to existing drawings or worn parts. The non-leaded metallic sleeve bearing, for example, provides a 1-1/2 in bore, 1-7/8 in OD, and 1-1/2 in length, with a temperature range that covers many industrial environments. General-purpose bronze sleeve bearings cover a wider temperature span, making them applicable in high-temperature or cryogenic-adjacent processes where standard lubricants may not be suitable. Bunting Bearings also manufactures flanged bearings and other plain bearing configurations, though the current 3G Electric listing focuses on straight sleeve bearings. The product summaries indicate common use in conveyors, pumps, and gearboxes, which aligns with the typical deployment of bronze sleeve bearings in continuous-duty machinery. 3G Electric does not modify or rebrand these components; they are supplied as Bunting Bearings-manufactured parts with the corresponding manufacturer part numbers. For procurement specialists, this means traceability to the original manufacturer's specifications and the ability to request quotes based on exact part numbers. The availability of multi-pack options, such as 3-pack quantities for certain small-bore sizes, can simplify inventory management for maintenance operations that consume bearings in sets. Overall, the Bunting Bearings line at 3G Electric addresses the need for plain bearing components in industrial equipment, with a focus on bronze and non-leaded metallic materials, broad temperature ratings, and a range of inch-based sizes. 3G Electric supports this line by providing product data, part-number search, and global shipping coordination, allowing buyers to source Bunting Bearings sleeve bearings alongside other industrial equipment from a single supplier.
