Take a closer look at Cat linkage pins & bearings

Cat linkage pins and bearings are designed for outstanding strength and resistance to wear from abrasive and high-load conditions. Because they perform better and last longer, you get high productivity at lower costs.

At Caterpillar, all the machine components are designed at the same time to precisely match machine and application requirements to every nut, bolt, seal and pin. This “system design” ensures all components work at top performance. Take a look at the key design advantages of Cat linkage pins and discover why competitive pins just can’t match up.

Linkage Pins for
Wheel Loaders

Wheel loaders are no stranger to abrasive and high load conditions. Which is why inspection, maintenance and proper pin replacement are crucial to the performance of your machine. Warn and broken parts or loose bolts can cause inaccuracies leading the operator to an overload or underload situation. Here’s how to safely check the pins and assemblies on your wheel loader and what to look for during inspection.

Linkage Pins
for excavators

Pins are an important part to the productivity of your excavator but is not something you often think about. While it may be low on the priority list, it’s high on the productivity list. The bucket linkage on your excavator takes on the toughest part of your work, so it’s important to look for any worn, broken or missing parts. Here’s what to look for during your daily walk around inspection, beyond just the obvious issues. And you’ll see why spending a little more money upfront, can save you big dollars in the long run.

Linkage Pins
for backhoe loaders

Backhoe loader pin assemblies can have a significant impact on productivity. When properly maintained, Cat linkage pins and pin assemblies — which are designed for outstanding strength and resistance to wear in abrasive and high-load conditions — perform better and last longer. Want to improve safety, avoid failures and prevent downtime? Watch and see how to get the most out of Cat linkage pins’ superior strength and wear resistance.

Linkage Pins
for dozers

Dozers are the heavy-duty earth movers of most construction sites. Pushing through rough terrain can take a toll on your pin joints. Performance of those pins is critical to make sure that the blade is penetrating into the ground as effectively as it can. And the number one cause of pin failures is lack of lubrication, which can cost you up to 16 hours of downtime and thousands of dollars in unplanned repairs. Take a look at how to safely inspect the push arm pins along the back of the blade and, more importantly, what to look for during that inspection.

Linkage Pins for
Motor Graders

Motor graders clear the way for machines and vehicles in all kind of conditions. From grading dirt and gravel to snow removal, the components take on tough materials. And the pins, joints and linkage assemblies — while often overlooked — can have a direct impact on motor grader performance. Having a loose pin can lead to downtime, failure, inaccuracy or rework. Here’s what to properly look for while inspecting the moldboard pivot pin and why overall proper maintenance is important to putting down a good grade.

Designed to deliver
more uptime

The same world-leading engineering and manufacturing that builds Cat machines goes into the design of every Cat linkage pin and bearing. The strength and surface design of Cat linkage pins and bearings provides exceptional protection from damage and wear that can lead to poor performance, failure and unnecessary service repairs.

Outstanding strength & fatigue life

Cat linkage pins are hardened to a deeper level than competitive pins. This makes them stronger and more resistant to high load conditions.

High surface hardness & ultra-fine finishes

The surface of Cat linkage pins makes them highly resistant to abrasive wear. Ultra-fine surface finishes give smoother performance and lower wear rates.

Outstanding chrome thickness

Where chrome pins are required, outstanding chrome thickness prevents damage to the pin surface, reduces the risk of galling and improves the life of the pin.

Cat Linkage Pins & Bearings crush the competition

Caterpillar side-by-side testing with competitive pins reveals:

Competitors struggle to match Cat specifications

Poor welds can lead to broken retention systems, resulting in damage to the pin joint. If the pin works its way out of the bore, it could cause major machine damage, work stoppage and downtime.

Cat linkage pins have a heat treat depth up to 3X greater than the competition

Linkage pins that aren't as strong as Cat are more likely to fail — and lead to avoidable repairs and downtime. Keep costs low by using genuine Cat linkage pins.

Linkage pin maintenance
really matters

Linkage pin maintenance may not be high on the priority list, but it should be. Linkage pin joints are critical to the productivity of buckets, blades and many work tools. Without regular inspection and lubrication, your pins will not deliver the life and performance they are designed for. Loose pin joints can even affect a machine’s ability to perform precise tasks such as grading or payload monitoring. Include pin and seal inspections in your daily walk-around, so you get the most out of your pin and machine investment.
