Center Flange Bronze Bushing With Solid Graphite Inserts Oilless Plain Bearing For Mould & Automation Equipment JEGB/JEGBK

Product Description:

Middle flanged graphite plugged bronze bushing is made of high-strength bronze alloy with embedded solid graphite for dry lubrication. The middle flange structure realizes central axial limiting during installation. It adapts to low-speed and heavy-load operating conditions without continuous oil filling. Widely applied to automation equipment, molds, textile machinery, hydraulic and engineering machinery components.

Product Overview

This center flange bronze bushing features solid graphite inserts positioned around the cylindrical bore and the centrally located flange face. Designed specifically for mould and automation equipment, the center flange provides axial location from a single, centrally positioned reference point, simplifying assembly and ensuring consistent positioning. The graphite inserts deliver maintenance-free lubrication for both radial guidance and axial thrust loads. The bronze substrate offers corrosion resistance and load capacity up to 200 N/mm² static. Custom dimensions, graphite patterns, and flange configurations available to meet specific mould and automation requirements.

Frequently Asked Questions
What is the advantage of a center flange over end flanges
Center flange provides a single axial reference point, simplifying assembly and reducing the need for precise counterbore depths on both sides. It is particularly advantageous in mould and automation applications where space constraints exist.
How are graphite inserts distributed on the center flange
Graphite inserts are arranged in a circular pattern on the center flange face. Typically 8-16 inserts depending on flange diameter, providing uniform lubrication for axial thrust loads in both directions.
Can the center flange position be adjusted from standard
Yes. While the standard center flange is positioned at the midpoint of the bushing length, custom flange positions can be specified to meet specific application requirements.
What is the recommended installation method for center flange bearings
Press fit using a tool that contacts both the flange face and the bushing outer diameter. The center flange requires counterbore on both sides of the housing for proper seating and retention.
How to determine when to replace a center 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.
