Hydraulic cylinder seals form a barrier between different components in a hydraulic cylinder. They are made with specific materials that adjust to varying clearance gap sizes and must be strong enough to withstand the shear stress created by system pressure.

Wheel bearings may sound complex, but their function is fairly simple. At the very basic level, wheel bearings are metal rings that connect the wheel and the axle. Within the metal ring is a series of ball bearings or tapered bearings, which help the wheel rotate efficiently and effectively, aiding in acceleration, braking, cornering, steering, and more vital driving functions.

In addition, the buffer seal cushions the rod from shock and vibration, increasing the life of the cylinder and its components. Rod and buffer seals are suitable for mobile and industrial applications, such as agricultural and construction equipment, where they are exposed to dirt, dust, and moisture.

Choosing suitable seal material is crucial, as it determines the overall quality and durability of hydraulic seals. Your manufacturer can suggest appropriate materials - whether you need hydraulic seal rings, o-rings, or any other type of seal -  to meet specific application needs. Below are the most common materials used to create seals:

These rings are available in metallic and nonmetallic options. Factors such as the diameter of the rod and piston, the stroke length, pressure, type of seal, and lubrication must be considered when selecting guide rings.

Guide rings are mounted on pistons and piston rods of hydraulic cylinders to absorb side loads and prevent metal-to-metal contact between sliding parts, such as rod and gland/piston and bore. They are typically placed inward of both the rod and buffer seal and should be lubricated on assembly with the same lubricant used in the hydraulic system.

The difference between a rod seal vs. piston seal: Rod seals are flexible and keep pressure in and contaminants out, while piston seals are rigid seals that keep pressure in and lubricate in.

When selecting hydraulics cylinders seals, it is essential to consider the type of surfaces they will be used on. A static seal should be employed if there is no relative motion between mating surfaces. On the other hand, if there is motion between surfaces (either reciprocating or oscillating), then a dynamic seal should be used.

Leaking or damaged seals can seriously impact your hydraulic system's performance. Trust our experts to select the right seals for your application and perform quality resealing services.

Piston seals, also known as piston rings, are mechanical seals that reduce leakage between components in a reciprocating motion. Therefore, the primary function of a hydraulic piston seal is to form a seal between the cylinder tube and piston, preventing the leakage of lubricants and gases.

When you visit any of our locally run service centers for wheel bearing replacement, you can rest assured that the job will be done right - that’s why each GreatWater-affiliated shop offers an industry-leading 3 Year/36,000 Mile Nationwide Warranty. But you can count on more than just premium service when you bring your vehicle to any of our partner locations, expect a first-rate customer experience as well. Â

Most quality wheel bearings can last anywhere from 100,000 to 150,000 miles before replacement is necessary. However, once it’s time for your vehicle’s wheel bearings to be replaced it’s important to do so quickly to keep your vehicle running smoothly and safely.Â

Wiper seals keep dirt, debris, and other contaminants from entering a system or machine. They are typically used for applications such as hydraulic cylinders, pumps, and valves and can be made from various materials, including rubber, polyurethane, and thermoplastic elastomers.

Different types of sealing are available for hydraulic cylinders, ranging from simple O-rings to complex rotary seals, hydraulic ram seals, and hydraulic oil seals. Depending on the application, the type of seal required will vary; but all seals serve the same purpose of creating a secure, fluid-tight seal.

In this blog, we look at how hydraulic cylinder seals are designed to prevent leakage, the main types of seals, and the materials they are made of to withstand high pressure.

That might be the best way to describe a wheel bearing - a key component to safe and efficient driving. A bad wheel bearing, however, can really impact your driving - and your safety. And it's a big part of why a faulty wheel bearing should be immediately serviced.

With a wide variety of hydraulic seals available, it is essential to select wisely to ensure cost-effective hydraulic cylinder repairs. Doing so will help to guarantee a long operating life and improved performance over the lifetime of the hydraulic cylinder. Incorrectly sealing equipment can lead to premature wear and eventual failure.

However, it is worth noting that the conditions you drive in can impact how quickly your bearings will need to be replaced. For instance, if you regularly drive in muddy or wet conditions, water and other contaminants could wear away at bearings faster than normal.

A hydraulic cylinder seal protects the hydraulic fluid and prevents the hydraulic system's components from mixing with external fluids. They also help to improve a system's overall efficiency and reliability, among other things:

As a hydraulic cylinder repair company, our team has been resealing hydraulic cylinders for over 30 years. We can help you no matter what your hydraulic system needs, and we are always happy to offer seal recommendations and answer any questions.

Hydraulic cylinder seals are an integral part of any hydraulic system because they control and maintain the pressure and movement of hydraulic fluid. Without them, hydraulic systems can't work correctly.

The correct  hydraulic cylinder seals, will maintain the integrity of the machine's system and extend its working life. Our hydraulic cylinder resealing services ensure such equipment runs at peak performance.

While you may not be able to immediately visually identify a faulty wheel bearing based on its tough-to-access location between the wheel and the axle, you can listen and feel for signs of an issue.

In this post, we'll help you understand the importance of wheel bearings, how to identify wheel bearing problems, and how any of our local GreatWater-affiliated shops can help maintain and replace these key components so you can hit the road with confidence again.

Because of their long lifespan, failure is usually caused by the typical everyday wear and tear from driving your vehicle over time.

Hydraulic rod seals consist of a metal rod inserted in a rubber or plastic sealing element. The sealing part conforms to the rod surface, creating a tight seal that prevents internal pressure from escaping and external contaminants from entering the cylinder.

If any of the signs and symptoms we mentioned above sound familiar, then it's important to have your wheel bearings inspected. While you could possibly do this yourself at home with the help of a carjack, it's probably best to just leave it to the pros by scheduling an appointment at any of our local service centers for a thorough assessment.

For more information on the importance of a wheel bearing and how to know when it might be time to replace one or more of your vehicle's bearings, contact or visit your nearest GreatWater service center today.Â

They also help maintain the pressure within the cylinder, allowing the piston to move efficiently. Piston seals are used in various applications, such as air compressors, hydraulic pumps, and internal combustion engines. As critical components in any reciprocating system, they ensure the efficient movement of the parts while keeping the system sealed and maintaining the pressure within.

Having done thousands of repairs, we have extensive knowledge and experience to expertly service your repairs and perform preventative maintenance. We also have a large inventory of seals and stock common steel shapes if your repair requires fabrication. If you’re looking for experienced and professional hydraulic repair service, contact Cylinders, Inc. today!

Designed with a lip that scrapes the system's surface when it moves, they eliminate any particles that may have accumulated. Additionally, wiper seals provide an extra barrier against entering liquids and gases. They are commonly used in conjunction with other seals such as O-rings, and rod seals to provide a comprehensive sealing solution.
