One-Flange Self-lubricating Bronze Bushing Graphite Plugged Sliding Sleeve Bearing JEFW

Product Description:

Single flanged graphite plugged bronze bushing is manufactured from high-strength bronze alloy embedded with solid graphite for dry lubrication. The single flange structure provides axial positioning during installation. It can operate under low-speed and heavy-load conditions without continuous oil supply. Widely used for injection molds, automation equipment, textile machinery, construction machinery and hydraulic components.

One-Flange Self-lubricating Bronze Bushing

This one-flange self-lubricating bronze bushing features a single integral flange located at one end of the bushing, providing axial location from a single reference point while the opposite end remains free. The flange contains graphite plugs distributed across its face, while the cylindrical bore also features graphite plugs for continuous lubrication. This configuration simplifies installation in applications where axial retention is required on only one side. The bronze substrate supports static loads up to 200 N/mm². Custom dimensions, flange thickness, and graphite patterns available to meet specific sliding sleeve requirements.

Single Flange Design One flange provides axial location from a single reference point. Simplifies installation in applications where only one side requires retention.
Graphite Plugged Lubrication Graphite plugs on bore and flange face deliver maintenance-free lubrication for sliding sleeve applications without external oil.
High Load Capacity Bronze substrate supports static loads up to 200 N/mm². Suitable for heavy duty sliding sleeve and guide applications.
Customizable Configuration Dimensions, flange thickness, graphite pattern, and bore tolerances adjustable to meet specific application requirements.

Frequently Asked Questions
What is the advantage of a single flange over dual flange
A single flange provides axial location from one reference point only, simplifying installation in applications where the opposite end requires free movement or where space constraints limit flange clearance.
How are graphite plugs distributed on the single flange
Graphite plugs are arranged in a circular pattern on the single flange face. Typically 6-14 plugs depending on flange diameter, providing uniform lubrication for axial thrust loads.
Can the flange position be adjusted from standard
Yes. While the standard single flange is positioned at the bushing end, custom flange positions along the length can be specified to meet specific application requirements.
What is the recommended installation method for single flange bearings
Press fit using a tool contacting the flange face uniformly. The opposite end can be inserted freely. Counterbore depth must match flange thickness for proper seating.
How to determine when to replace a single flange bearing
Replace when bore diameter wear exceeds 0.06mm, flange thickness wear exceeds 0.08mm, or when graphite on the flange face falls below 12% of original surface area.
