Bushing E90: page 12
Bronze bushings remain a classic solution for moving mechanisms, and the E90 series is among the most widely used perforated variants in this category.
The bronze used in the E90 bushings is a special alloy designed for wear resistance, and the holes on the surface are sized and spaced to retain lubricant without compromising the bushing’s structural integrity. During initial installation, it is recommended to fill the perforations with grease or a compatible lubricant so that the self-lubricating effect begins from the very first hours of operation, rather than only after a running-in period.
E90 bronze bushings: a solution for fixing and supporting moving mechanisms
E90 bushings are made from bronze, a material with natural self-lubricating properties, suitable for joints subjected to repeated movement. Their role is to support and guide the moving component — usually a bolt or a shaft — whilst keeping mechanical play within normal limits, even after thousands of operating cycles.
How E90 bushings help reduce play and wear
The perforations on the surface of the bushing retain a small amount of lubricant, which is gradually released during operation. This self-lubrication reduces direct metal-to-metal friction, which means less wear on both the bushing and the component it interfaces with. In the long term, the clearance in the joint remains stable for longer than with a bushing without this structure.
Selecting perforated bronze bushings according to load and operating conditions
For heavier loads or collar-mounted applications, HRC2 bushings are an option worth considering, as are EB65.02 bushings for environments with varying demands. If further friction reduction is required, JDB bushings with graphite inserts are worth comparing, while XA bushings are a suitable option for versatility in agricultural machinery.
The benefits of buying E90 bushings from the Hydraulic Seals Store
The E90 bushings in stock at Hydraulic Seals Store are size-checked and consistently available, so you won’t have to wait weeks for a simple part. Ordering online is quick, and delivery arrives in time for scheduled repairs.
The E90 series remains one of the most popular types of bronze bushings for general maintenance, precisely because of its good balance between price and service life. For machinery with multiple identical pivot points, ordering a complete set of E90 bushings in the same size simplifies both your own stock management and the scheduling of future maintenance.
