Hillman Bronze Sleeve Bearing 58077 0.75in Oil Impregnated Sintered

Description

Product Overview

The Hillman 58077 bronze sleeve bearing is engineered for precision and durability in a wide range of industrial settings. As part of The Hillman Group’s trusted line of plain bearings, this model combines a compact 0.75‑inch diameter with a robust sintered bronze construction, delivering reliable performance for shafts and spindles that demand consistent support. The bearing’s dimensions—2.4 x 1.7 x 1.6 inches—fit easily into standard housings while the 0.31‑inch thickness provides a solid, level surface that distributes load evenly across the contact area.

Designed with an oil‑impregnated surface, the bearing offers a low‑friction interface that minimizes heat buildup and wear during continuous operation. The oil is sealed within the bronze matrix, ensuring a steady supply of lubrication without the need for frequent re‑application. This feature not only extends the service interval but also reduces maintenance costs, making the bearing an economical choice for high‑volume production lines.

Sintered bronze, the core material of this sleeve bearing, is renowned for its wear resistance and ability to retain structural integrity under heavy loads. The sintering process creates a porous yet strong metal lattice that absorbs shock and dampens vibration, protecting adjacent components from premature failure. Coupled with a plain bearing design, the product provides a smooth, level surface that accommodates slight misalignments while maintaining precise rotational accuracy.

The bearing is compatible with standard oil lubricants, allowing users to select the most appropriate fluid for their specific application. Its universal fit and straightforward installation make it a versatile component for a variety of machines, from conveyor rollers to motor shafts. The product ships as a single unit, identified by part number 58077 and UPC 008236167184, ensuring easy inventory management and traceability.

Usage

In industrial environments, the Hillman 58077 sleeve bearing excels in applications where continuous rotation and load bearing are critical. It is commonly employed in conveyor systems, where it supports rollers that transport materials across production floors. The low‑friction, oil‑impregnated surface reduces energy consumption, allowing motors to operate more efficiently and extending the lifespan of the entire conveyance system.

Gearboxes and motor assemblies also benefit from the bearing’s robust design. When mounted on shafts within a gearbox, the bearing absorbs torque fluctuations and mitigates the impact of sudden load changes. Its sintered bronze composition ensures that even under high‑stress conditions, the bearing maintains dimensional stability, preventing axial drift and preserving gear alignment.

Maintenance teams appreciate the bearing’s self‑lubricating properties, which simplify routine upkeep. Because the oil is embedded within the bronze matrix, the bearing requires only periodic visual inspections rather than regular oiling cycles. When lubrication is needed, a simple application of compatible oil to the exterior surface restores optimal performance without disassembly.

Installation is straightforward: the bearing slides onto the shaft with a snug fit, and the surrounding housing secures it in place. For best results, ensure the shaft is clean and free of debris before mounting. Apply a thin layer of oil to the outer surface if additional lubrication is desired, then tighten the housing bolts to the manufacturer’s torque specifications. This process minimizes the risk of misalignment and guarantees smooth operation from day one.

FAQ

What size shaft can this bearing accommodate?

The Hillman 58077 sleeve bearing is designed for shafts up to 0.75 inches (approximately 19 mm) in diameter, making it suitable for a wide range of small‑to‑medium industrial equipment.

Is additional lubrication required during operation?

The bearing’s oil‑impregnated bronze matrix provides continuous lubrication, so routine re‑lubrication is not necessary. However, applying a compatible oil to the exterior surface during installation can enhance performance in high‑load environments.

Can this bearing be used in high‑temperature applications?

Sintered bronze maintains its strength and dimensional stability at elevated temperatures, but for extreme heat conditions above 200 °C (392 °F), it is recommended to verify compatibility with the specific oil and operating environment.

What is the warranty coverage for this product?

Hillman offers a limited warranty that covers manufacturing defects and material failures for a period of one year from the date of purchase, providing confidence in the bearing’s quality and durability.

How do I install the bearing correctly?

Start by cleaning the shaft and housing to remove any debris. Slide the bearing onto the shaft, ensuring a snug fit, then secure the housing with the recommended torque. Apply a thin layer of compatible oil if additional lubrication is desired, and verify that the bearing rotates freely without binding.
