Bronze Bushings

Why Are Excel Replacement Parts So Good?

Fit, form and function – that is what Excel guarantees in every replacement part we deliver. Our Quality Assurance Department scrutinizes every dimension with exacting tolerances to be sure your part is perfect in every way, giving your operation an unbelievable value. Less expensive than the OEM and the highest quality in the business… sounds too good to be true, doesn’t it? There are many reasons that Excel is your best choice, but here are four compelling facts that make our bushings… Simply the Best!

Higher Tensile Strength

Maximum Tin Content Makes Our Bushings Stronger. In order to maximize tensile strength, Excel certifies our crusher bronze to the top end of the CDA specification for tin. Tougher bushings mean less down time and fewer replacement cycles. Tin is the most expensive ingredient in the metallurgy of crusher bronze alloys. Some competitors minimize this important component in order to increase their bottom line. We use the maximum percentage of tin to increase your bottom line. That’s a difference you can bank on!

Uniform Lead Dispersion

Unique Chilling Process Stops Migration
Our foundry utilizes a unique chilling process that assures even dispersion of lead throughout the casting. Standard foundry molding techniques allow uneven, non-directional cooling that can cause lead migration. Even dispersion of lead provides consistent lubricity and heat dissipation which increase bushing life and reduce unexpected failure. This proprietary process does not add to your cost or the turnaround time of your part. The small things make a big difference in the long run.

Perfect Concentricity

Simultaneous “4-Axis” Turning Ensures Concentricity. Extensive investment in our equipment, our people and our process gives Excel many unique capabilities. Excel incorporates a special “Pinch Turning” method in the machining of our crusher bushings which simultaneously cuts the OD and ID at the same time. Using this technology guarantees absolute concentricity. Another Excel process that makes a difference!

Porosity-Free/Uniform Grain Structure

Centrifugal Casting Technique Ensures Alloy Integrity. The purity of our raw materials, coupled with controlled, directional solidification during the casting process creates a tighter, denser grain structure in our alloys while eliminating 99.9% of the gas pockets that produce porosity. The integrity of Excel’s grain structure and the purity of our alloys ensure strong, long lasting replacement parts.

Marine Applications

Excel also produces bronze replacement components specifically tailored for marine, heavy-work applications. Whether you’re looking for replacement rudder bearings or stern tube bearings or sleeves, Excel can supply an application-specific bushing to suit your vessel. Excel bronze bushings can handle offshore, coastal, and inland marine operations in a variety of aquatic conditions and qualities. Our in-house metallurgy department can also work with you to design a custom alloy specifically suited to your precise needs and working environments.
