Bunting Bearings EP101420 Sleeve Bearing Bronze 5/8 in Bore 1 1/4 in Length PK3

Bronze Sleeve Bearing 5/8 in Bore

This Bunting Bearings sleeve bearing is a plain cylindrical bushing made from sintered bronze with a 5/8 in bore and 1 1/4 in overall length. It is designed for power transmission applications requiring a simple, self-lubricating journal bearing. The bearing is sold in a pack of three units. It suits maintenance teams and machine shops fitting or replacing bushings in inch-measurement equipment.

Temperature Limits and Lubrication

The bearing operates between 10 and 220 Degrees F using embedded SAE 30 oil for self-lubrication. This solid lubricant reservoir eliminates the need for external grease lines or periodic relubrication. Performance depends on the oil remaining within the sintered matrix; sustained operation near the upper temperature limit can reduce lubricant viscosity and bearing life. The non-flanged design requires axial location by other means in the housing.

Upgrade From Solid Bushings

This bearing replaces solid bronze or plastic bushings that require manual greasing or cannot tolerate the stated temperature range. The jump is worth it when maintenance intervals must be extended or when vacuum environments rule out external lubricants. It does not suit applications needing flanged axial retention, corrosion resistance beyond standard bronze, or load capacities exceeding the material limits of sintered bronze. Buyers needing sealed or rolling-element bearings should look elsewhere.
