Bunting Bearings EXEF050712 Lubricant Flange Bearing Pack of 3

Description

Product Overview

The Bunting Bearings EXEF050712 sleeve bearing is engineered for demanding industrial power‑transmission applications where reliability and longevity are essential. Constructed from high‑quality powdered metal, the bearing offers excellent load‑carrying capacity while maintaining dimensional stability across a wide temperature range. An extra layer of PTFE lubricant is applied to the flange surface, providing a low‑friction interface that reduces wear and extends service intervals.

The bearing’s dimensions—5/16 inch bore, 7/16 inch outer diameter, and a 9/16 inch flange—fit standard shaft sizes and allow easy installation in existing equipment. With a compact length of 3/4 inch and a flange thickness of 1/16 inch, the unit occupies minimal space while delivering robust performance. Certified to meet ASTM chemical and physical property standards, this flanged sleeve bearing is suitable for low‑speed machinery, conveyors, and gearboxes that operate between 10 °F and 220 °F.

Beyond its core mechanical attributes, the EXEF050712 model incorporates design features that simplify maintenance. The PTFE‑infused flange eliminates the need for frequent re‑greasing, and the powdered‑metal matrix resists corrosion from typical industrial fluids such as oils, solvents, and coolants. The pack of three units provides cost‑effective coverage for multiple shafts or replacement stock, ensuring continuous operation with minimal downtime.

Manufactured by Bunting Bearings, a brand with a long history of precision bearing production, this component benefits from rigorous quality control processes. Each bearing undergoes dimensional verification, load testing, and lubricant adhesion checks before leaving the factory. The result is a consistent, high‑performance product that meets the expectations of engineers and maintenance professionals alike.

Usage

In typical industrial settings, the EXEF050712 bearing is employed in low‑speed drive trains, material handling equipment, and auxiliary shafts that require a stable, low‑friction support. Its PTFE‑lubricated flange reduces the need for frequent re‑greasing, making it ideal for installations that are difficult to access or operate in clean‑room environments.

The bearing tolerates temperature fluctuations from freezing conditions up to 220 °F, allowing use in refrigerated warehouses, hot‑shop machining areas, and outdoor machinery exposed to seasonal changes. Because the bearing conforms to ASTM specifications, it resists corrosion from chemicals commonly found in manufacturing plants, such as oils, solvents, and coolants.

Engineers often select this model for applications that demand quiet operation, such as precision conveyors, packaging lines, and textile machinery, where reduced vibration and noise contribute to product quality and worker safety. The three‑piece pack simplifies inventory management, enabling maintenance teams to replace worn bearings quickly without searching for exact part numbers.

Additional use cases include pump shafts in chemical processing, fan assemblies in HVAC systems, and auxiliary drives in agricultural equipment. In each scenario, the bearing’s combination of durability, low friction, and temperature resilience provides a dependable solution that minimizes unexpected downtime.

FAQ

What size shaft does the EXEF050712 bearing fit?

The bearing is designed for a 5/16 inch bore, making it compatible with shafts of that diameter. It can be installed on standard shafts without the need for additional adapters.

How often does the PTFE lubricant need to be re‑applied?

The PTFE coating is bonded to the flange during manufacturing and is intended to last the life of the bearing under normal operating conditions. Re‑application is rarely required unless the bearing is exposed to extreme abrasive environments.

Is the bearing suitable for high‑speed applications?

While the EXEF050712 excels in low‑speed, high‑torque scenarios, it is not optimized for very high rotational speeds. For high‑speed requirements, a bearing specifically rated for those speeds should be selected.

Can I purchase a single bearing instead of the pack of three?

Yes, single units are available upon request, but the standard packaging is a three‑piece pack to provide cost‑effective coverage for multiple shafts and to simplify inventory management.

What certifications does the bearing meet?

The bearing conforms to ASTM standards for chemical and physical properties, ensuring it meets industry‑accepted criteria for durability, corrosion resistance, and material quality.
