But sealed wheel bearings are non-serviceable and should never be repaired, only replaced. Even if a pro suggests repairing a bearing, don’t let them. Trying to reuse a damaged wheel bearing can result in an accident and severe injury.

The importance of having a shaft seal on industrial mixers and blenders is evident to any plant manager. The problem has historically always been with designing a seal to overcome the risk of wear and batch contamination. CinchSeal’s advanced rotary shaft seal assembly solves the design issue, improving equipment lifespan and performance.

Friction from a failing wheel bearing produces heat. After driving, without touching the tires or wheels, carefully walk around your vehicle and use a non-touch thermometer to measure if one is hotter than the others.

Advanced (air-purged, PTFE and silicone) rotary, or radial, shaft seals are becoming the standard as everyone from food processors to electric vehicle and cement manufacturers replace or upgrade their equipment from lip seals and packing seals.

Since 1994, CinchSeal has been a major manufacturer of rotary shaft seals. CinchSeal products serve as replacements and upgrades that make the need for machine replacement less likely.

Simply stated, wheel bearings allow cars and trucks to run smoother and more efficiently by reducing friction and supporting vehicle weight. When they start to fail, you can usually tell.

Unlike unbalanced tires, shaking caused by a bad wheel bearing should be obvious from the side of the car where the bearing is failing.

NOTE: Whether you DIY or your mechanic replaces the bearing, always install a new axle hub nut. Most hub nuts are prevailing torque fasteners, used on critical components (like securing axle shafts to hub bearings) where a loose nut could lead to disastrous consequences.

High-performance, leak-free, PTFE and air-purged rotary shaft seals, such as those designed and manufactured by CinchSeal, outperform alternatives like O-rings, braided packing seals, mechanical face seals, lip seals, and other outdated designs. Advanced rotary shaft seals offer a major improvement in:

Self-adjusting rotary shaft seals by CinchSeal provide fast ROI, protect bearings and gearboxes, eliminate shaft wear and leakage, and reduce unscheduled maintenance and downtime. A global leader in innovative rotary seal manufacturing for over 25 years, CinchSeal serves top companies around the world in industries from food and powder manufacturing to chemical processing. Our rotary seals are ideal for industrial mixers, screw conveyors, and bulk-handling equipment.

On many vehicles, the ABS sensor is built into the wheel bearing, or it’s externally mounted adjacent to the spinning part of the bearing where the sensor measures vehicle speed. Damaged from a wobbly wheel bearing, the sensor will send erratic readings to the vehicle’s computer, illuminating the ABS light.

You can service or replace tapered wheel bearings yourself. Never reuse any wheel bearing that’s loose, worn, noisy or shows any signs of wear.

A bad wheel bearing can cause a tire/wheel to move or glide unevenly or sluggishly. It can also cause your brakes to drag, pulling your vehicle to one side when you try to stop.

The average cost to replace a sealed wheel hub bearing is $350 per wheel. However, depending on the make and model, shop labor rate, the cost of the bearing itself and any additional damage, the total could exceed $1,000.

Depending on the vehicle, you can save hundreds in labor replacing wheel bearings yourself. Most auto parts stores will lend you the specialty tools and equipment needed to replace a wheel bearing.

The cage and rollers are held together inside a hardened metal ring called a “race.” The seal keeps grease in and damaging water and debris out. Wheel bearings are installed inside, and secured to, the suspension, either by press fit, bolts or a snap-ring. Once mounted, the wheel bearing rides on the axle shaft, allowing the tire/wheel to spin effortlessly.

You’ll hear clicking, cracking, grinding, snapping, or whining noises coming from your wheels or tires. They’ll increase when accelerating or turning.

Read on to learn the most common bad wheel bearing symptoms, based on my experience (50 years in the industry) and that of Joe Simes, a National Institute for Automotive Service Excellence (ASE) certified and Toyota master technician. But first, a little background.

CinchSeal rotary shaft seals perform so well that they alone carry United States Department of Agriculture certification for poultry and dairy processing. This means the seals can be trusted to prevent cross-contamination and help keep food safe. But the seals’ high performance is evident across many industries.

On modern front- and four-wheel drive cars, wheel bearings are a set of permanently sealed, precisely machined steel ball or straight roller bearings. The balls, or rollers, are encased in a “cage” that supports the bearings, allowing them to rotate freely.

Rotary shaft seals are critical components in industrial equipment, designed to keep product flow contained while blocking contaminants from entering machinery. These seals create a tight barrier around rotating shafts, ensuring optimal performance in applications such as screw conveyors, ribbon blenders, mixers, and other bulk-handling equipment.Whether handling liquids, gels, powders, or granular materials, rotary shaft seals prevent leaks, reduce product loss, and protect equipment from contamination. Their role is especially crucial in demanding industrial environments where efficient and reliable sealing directly impacts production costs and equipment longevity.

Absolutely not. It’s crucial to get bad wheel bearings diagnosed and replaced ASAP. If not, you could lose a wheel or get in an accident.

Innovative design has been instrumental in bringing about CinchSeal rotary seals’ high levels of performance that leads to cost savings. For example, CinchSeal rotary seals:

According to Simes, a failing wheel bearing will likely produce a soft, faint vibration that’s felt before it’s heard. There may also be a vague rhythmic humming or droning sound that increases over time and with speed.
