Bunting Bearings EXEF121412 Extra Lubricant with PTFE, Flange Bearing, Powdered Metal, SAE 841 3/4 ” Bore x 7/8 ” OD x 3/4 ” Length 1 1/8 ” Flange OD x 1/8 ” Flange Thickness (3 Pack)

Description

Product Overview

The Bunting Bearings EXEF121412 flanged sleeve bearing is engineered for demanding industrial environments where reliability, durability, and precision are paramount. Constructed from SAE 841 powdered‑metal, the bearing offers exceptional load‑carrying capacity while maintaining a lightweight profile. The PTFE‑infused extra lubricant provides a low‑friction interface that reduces wear and extends service life, even in low‑speed, non‑magnetic applications. With a bore of 3/4″ and an outer diameter of 7/8″, the bearing fits standard shafts and housings, while the 1 1/8″ flange OD and 1/8″ flange thickness ensure secure mounting. The product meets ASTM chemical and physical property standards, guaranteeing consistent performance across a temperature range of 10 °F to 220 °F. Its non‑magnetic nature makes it ideal for equipment that must avoid magnetic interference, and the corrosion‑resistant finish protects against harsh chemicals and moisture.

Usage

This flanged sleeve bearing excels in low‑speed machinery such as conveyors, mixers, and gear reducers where steady, quiet operation is essential. It is also suited for applications in the food processing, pharmaceutical, and chemical industries where non‑magnetic components are required to prevent product contamination. The bearing’s wide temperature tolerance allows it to function in refrigerated environments as well as heated processes, making it a versatile choice for both indoor and outdoor installations. Installation is straightforward: the flange aligns with the housing bore, and the bearing slides onto the shaft without the need for additional fasteners. Regular inspection and re‑lubrication, if necessary, will keep the bearing performing at peak efficiency throughout its service life.

FAQ

What size shaft can this bearing accommodate?

The bearing has a 3/4″ bore, making it compatible with shafts ranging from 0.70″ to 0.78″ in diameter, allowing for a small tolerance to ensure a snug fit.

Is the PTFE lubricant re‑applicable?

Yes, the PTFE‑infused lubricant can be refreshed during routine maintenance. Simply clean the bearing surface and apply a fresh layer of compatible PTFE‑based grease to maintain optimal performance.

Can this bearing be used in high‑temperature environments?

The bearing is rated for operation up to 220 °F. For applications exceeding this temperature, a different bearing material should be selected to avoid degradation.

What makes this bearing suitable for non‑magnetic applications?

Both the SAE 841 powdered‑metal alloy and the PTFE lubricant are non‑magnetic, ensuring the bearing does not attract or interfere with magnetic fields, which is critical in medical, aerospace, and precision instrumentation contexts.

How does the flange design simplify installation?

The 1 1/8″ flange OD and 1/8″ flange thickness provide a secure mounting surface that aligns with standard housing bores. This design eliminates the need for additional fasteners, reducing installation time and potential points of failure.
