Frequently asked questions
Common questions about BUNTING BEARINGS from 3G Electric.
What temperature range do Bunting Bearings general-purpose metallic sleeve bearings support?
The general-purpose metallic sleeve bearings listed by 3G Electric, such as MPN CB313532 and CB354636, are rated for operating temperatures from -450°F to 500°F. This range covers many high-temperature industrial processes and low-temperature applications. The non-leaded metallic sleeve bearing, MPN EBCB243012, has a narrower rating of -40°F to 400°F. Always verify the specific temperature limit for the exact part number, as ratings can vary by material and size.
What is the difference between the non-leaded metallic and general-purpose metallic sleeve bearings from Bunting Bearings?
The non-leaded metallic sleeve bearing, represented by MPN EBCB243012, is made of bronze but formulated without lead, which may be required in applications with environmental or health restrictions. It has a temperature range of -40°F to 400°F. The general-purpose metallic sleeve bearings, such as MPN CB313532, are also bronze but contain lead for enhanced machinability and lubricity, and they are rated from -450°F to 500°F. Both types handle radial loads in rotating or oscillating shaft applications.
Can Bunting Bearings sleeve bearings be used in pumps and conveyors?
Yes. The product summaries for Bunting Bearings sleeve bearings indicate common use in industrial machinery, conveyors, pumps, and gearboxes. These bearings support rotating shafts and reduce friction and wear under radial loads. For pump and conveyor applications, select the bore, outside diameter, and length to match the shaft and housing dimensions. Temperature rating should also be checked against the process conditions. The general-purpose bronze sleeve bearings are often chosen for their wide temperature range.
Are Bunting Bearings sleeve bearings available in multi-pack quantities?
Some Bunting Bearings sleeve bearings are supplied in multi-pack quantities. For example, MPN CB050808 (5/16 in bore, 1/2 in OD, 1 in length) and MPN CB162011 (1 in bore, 1-1/4 in OD, 1-3/8 in length) are listed as 3-packs. Other sizes, such as MPN CB313532 and MPN CB354636, are typically sold as individual pieces. Check the specific part number for packaging details when ordering from 3G Electric.
How do I select the correct Bunting Bearings sleeve bearing for my application?
Selection depends on shaft diameter (bore), housing bore (outside diameter), and available width (length). The Bunting Bearings sleeve bearings in the 3G Electric catalog range from 5/16 in to 2-3/16 in bore, 1/2 in to 2-7/8 in OD, and 1 in to 4-1/2 in length. Also consider the operating temperature and load type (radial or oscillating). For high-temperature applications, the general-purpose bronze bearings with -450°F to 500°F rating are suitable. For lead-free requirements, choose the non-leaded metallic type.
What materials are Bunting Bearings sleeve bearings made from?
The Bunting Bearings sleeve bearings listed by 3G Electric are made of bronze. The non-leaded metallic sleeve bearing (MPN EBCB243012) is a bronze alloy without lead. The general-purpose metallic sleeve bearings (e.g., MPN CB313532, CB354636, CB050808, CB303824, CB182224, CB202420, CB162011) are also bronze, typically containing lead for improved bearing properties. These materials provide good wear resistance and load capacity in plain bearing applications.
