We invite you to utilize and benefit from our 110 years in the seal industry, and a wealth of expertise. We are glad to assist with guidance, samples or pricing at your request.

Axial or radial play in the wheel or wheel hub. Should the wheel hub move up and down or in and out, the bearing may be worn.

The valves that control product flow within the facility are also sealed. Sometimes it is for assurance of the open or closed valve position, but often it’s to identify what is coming through the line. Seals can be color coded and marked to provide information about the valve it is on. Most can be printed with safety information, barcoding or other data as a producer may require. There are also seals that allow the user to write dates, times, their identity, or other details on the seal for manual control functions. Additionally, users might add a tag to the seal to provide even more detail.

For valves on transport vehicles including tank trucks and rail tankers there are other considerations. Tank trucks for short hauling and those carrying less sensitive commodities often use simple plastic pull up seals for their discharge and filling valves. The typical tank truck or rail tanker has a provision for a seal on the valve or the box covering the valve, so adjustable strap seals will work. Often the choice depends on the diameter of the seal opening. Meanwhile, trucks hauling fuels and high risk/high value products are sealed with heavy duty seals, usually cable seals. Within the AC&M line is most likely a seal that will fit the job.

In numerous industries, valves are sealed for safety, quality, cost control, and operational reasons. The seals are primarily used to confirm that a valve is in either a closed or opened position (LC =locked closed or LO=Locked open). But there are many other purposes seals serve.

Vibration in the steering wheel or vehicle body and/or wandering. Vibration and lack of directional stability could be consequences of loose or worn out wheel bearings.

Some applications are long term and some can require daily seal changes. A typical refinery can use thousands of seals in a year just to maintain internal valve operations. Food processors can use many more, and in both cases, this does not include seals on tank trucks entering and leaving the facility.

Water that enters a commercial building for operational needs, sanitary use, drinking, cooling, and fire protection passes through valves that are often sealed, to deter unauthorized opening or closing. The same is true for valves controlling intake and outflow of ingredients or finished products.

If the use is in an area where physical damage is possible or where strength is needed cable seals are the choice. AC&M has many options in cable seals, wire seals, and plastic seals.

Valve stem seal replacement

The complexity of wheel bearing replacement varies greatly depending on the vehicle make, model, year, the wheel position (front versus rear), and the drive type (AWD versus FWD):

Tire and wheel assembly does not turn smoothly. With the wheel jacked up, and the car not in gear, the wheel should rotate smoothly. Rough or inconsistent movement, which is often accompanied by noise, can signify damaged bearings. Be sure the brakes are not dragging as you perform this check.

No. Wheel bearing failure is usually gradual, although in some cases it starts immediately after the dramatic impact of the wheel and tire assembly with a deep pothole. Wheel bearings can sometimes make noise for quite some time before you experience a catastrophic failure that would result in complete separation of the wheel and tire assembly from the axle. Generally, the risk of sudden failure increases with the noise level. But strictly speaking, once the bearing has started to fail it is impossible to predict exactly when it will fail completely. So it should not continue to be driven. Were a failing bearing to seize or break while you are moving, you could experience loss of control of the vehicle. Once you receive a conclusive diagnostic that a wheel bearing has failed, replace the bearing promptly.

Sometimes the shape of a valve has no opening for a typical mechanical seal, but an adhesive security tape or label could be a solution.

Growling or grinding noise from a wheel. Failed or failing wheel bearings make a very characteristic growling noise which will grow louder as the bearing wear progresses. If you believe the wheel bearing noise is coming from one side of the car, you can self-diagnosis your wheel bearing as you drive the car by loading and unloading vehicle weight You can do this by “swerving” from side-to-side. For example, if the noise markedly increases when you swerve to left, which shifts the vehicle’s weight to the right, then it often indicates the wheel bearing on the right is failing.

The number of valve types, purposes for a seal, and the seal types used are limitless. Though some valves present unique challenges to finding an effective seal that fits, AC&M produces over 100 different tamper evident sealing devices, and variations. All are used, or can be used to seal one type of valve or another. We meet challenges in valve sealing and have done so worldwide for much of our 110 year history.

Wire seals and cable seals are often the best options as they can be easily pulled through a handle and then around a valve body, pipe or fixture. Wire seals have almost unlimited length options. However, strap seals can be used in many areas where the fit is right.

The other major use of tamper evident seals on valves is in transport. Tank trucks, rail tankers, and long distance pipelines have valves that are sealed.

On average, the cost for a Nissan Altima Wheel Bearings Replacement is $205 with $65 for parts and $140 for labor. Prices may vary depending on your location.

A wheel bearing assembly consists of rolling elements, such as hardened steel ball bearings or roller bearings, that roll on and around hardened steel bearing races. The wheel bearings support the front and rear axle, and all the weight of your car. Wheel bearings are made with a high-precision technique using extremely hard steel in order to withstand all the normal impacts that occur to the wheel and tire assembly as you drive along the road.

There are no fixed rules on which seal is best. The user needs to consider strength requirements, size, working environment, length of time it will be in use and any potential exposure to damaging chemicals. Also, it is important to consider the markings required and any color or coding needs. The budget is also a key factor in making a choice.

Manufacturing and processing systems in petroleum, chemical, food and beverage, pharmaceutical, plus power plants, and water/sewer plants have thousands of valves in use. These valves control ingredients, coolants, mixing, transfer, loading and filling of finished product and more – for both liquids and gasses.

Valve types vary, and the typical valve in a production facility or plant can range in size from very small to iron giants with handles of 1 meter or more in diameter. Many have unique placement and handle configurations which require a very flexible seal, both in length and bending capability.
