Bushing E90F: page 3

E90F bushings are the flanged version of the E90 series, designed for mounting points where an axial support surface is also required.

The flange on the E90F bushings absorbs the axial load that would otherwise cause the moving component to shift along the shaft, a common occurrence in steering systems and articulated arms operating at variable angles. The bronze material of the flange retains the same self-lubricating properties as the cylindrical body of the bushing so that the entire component resists wear uniformly, not just the radial contact area.

What are E90F bushings, and what is the role of the flange?

In addition to the basic function of a bronze bushing — guiding and supporting a moving pin or shaft — the flange at the end of the E90F bushing takes up part of the axial load and limits the lateral movement of adjacent components. It is particularly useful where the mounting location does not provide any other form of axial support.

How to choose the right E90F bushings for your equipment

In addition to the internal and external diameters, with the E90F you must also check the flange diameter and thickness to ensure a precise fit within the housing. For applications with similar mounting areas, it is also worth comparing XA bushings, E92 bushings, EB65.01 bushings or JDBF bushings, each with a different flange profile or material.

The benefits of buying E90F flanged bushings from Hydraulic Seals Store

Hydraulic Seals Store lists E90F bushings with all relevant dimensions — diameter, flange, length — to take the guesswork out of ordering. Fast delivery and up-to-date stock levels make all the difference when equipment is waiting for a single part to get back up and running.

The flange diameter and thickness are shown separately for each E90F variant in the catalogue, alongside the inner and outer diameters of the bushing body, so you can quickly check compatibility with the housing recess. For machinery where the flange plays an important structural role — for example, at the mounting points of a loader arm — it is recommended that the bushing be replaced as soon as signs of wear appear on the flange surface, not just on the cylindrical surface.
