![]() ![]() We pride ourselves on designing the right seal for the right application so please feel free to contact us or head over to our website at. And, because it's liquid tight it makes it a great choice for very challenging lubrication environments like flooded conditions. It has a stainless steel and a soft compliant face that are both precision lapped and pulled together by a magnetic force.Īlthough it is a contact seal, the self-lubricating material on the soft face will give it an extremely long sealing life. The VBMag, our contact design, operates a little bit differently. There are some applications that will require a contact seal. The incorporation of a unitizing ring eliminates metal-to-metal contact between the rotor and stator. GUARDIAN bearing isolators are composed of a patented Cam-Lock design and unitizing ring. Because it's non-contacting and totally non-wearing, it has an extremely long sealing life and makes it a great choice for the vast majority of our applications. GUARDIAN Bearing Isolator/Labyrinth Seal,Flangeless, 316SS, 1.750 inch Shaft, 2.875 inch Bore, 0.626 inch Width. Anything that tries to get into the bearing housing is going to come in through this pathway and, before it can get into the housing, it's going to be expelled through the bottom of the seal out the exposure port through gravity and centrifugal force. Our non-contact seals rely on a torturous pathway to create that ceiling interface. ProTech features the most effective labyrinth design for both dirt exclusion and oil. Statistics show the repair cost of typical equipment failure due to rubber lip seal deterioration can be 5 to 15 times greater than the cost to prevent the failure in the first place. Let's first talk about the non-contact seals. This is accomplished by using non-contact labyrinth seal technology. When bearing isolators are used in place of lip seals the repair, replacement and downtime costs for rotating equipment decreases substantially. Secondly, they both have the same main two components: a rotating element and a stationary element or a rotor and a stator. This will significantly prolong the life of your equipment and the life of your bearings. First and foremost, they have the same goal which is to retain lubrication and to exclude contaminants from entering your bearing housing. Broadly speaking those are non-contact compound Labyrinth seals and our contact bearing isolators. Bearing Isolator parts are made from tough materials such as Bronze, Nirtile rubber (NBR), Fluoro Rubber, and Polyacrylate Elastomer. This seal is designed to keep contaminants out while keeping lubrication and necessary materials in. ![]() Hi, my name is Chris Solfelt with Inpro/Seal and today we're going to talk about the different types of bearing isolators that we make here. Together, the rotor and stator form a multifaceted labyrinth seal. ![]() Custom designs are available for higher speeds, axial movement and high misalignment (STBM) conditions.Bearing Isolator Non-Contact vs.Pillow block design meets OEM specifications IEEE-841 to provide premium bearing protection on severe-duty electric motors Standard profiles are available to meet specific design requirement andĪnd multiple expulsion (drain) ports when directional installation is a concern Some cases, the energy savings alone offsets upgrade costs. Lower torque consumption which results in A labyrinth seal is a type of bearing isolator that combines contact and non-contact seal elements into a single component.With a bearing isolator solution, the seal is no longer the limiting factor for the bearings reaching the basic life rating stated by bearing manufacturers (L 10 rating). Labyrinth sealing technology applied to high performance materials allows the Parker ProTech LN Profile bearing isolator to operate far beyond the shaft speed limits of standard radial lip seals and avoids shaft wear. For more information, shop our selection of. With true non-contact ProTech designs there is nothing to wear out thereby extending mean time between failure (MTBF). EIS provides the highest quality Bearing Isolators and Seals from Industry leading supplier Garlock/Klozure. Unlike labyrinth bearing isolators which are non-contacting devices, IsoMag magnetic bearing isolators provide a positive seal that prevents leakage, protects against the ingress of internal contamination, and provides years of reliable service. pumps disallows lip seals and calls for either rotating labyrinth-style or. Manufacturing environment has been the primary driver behind companies’ decisions to convertįrom standard lip seals to bearing isolator-type seals. Inexpensive lip seals are sometimes used for sealing at the bearing housing. Utilize labyrinth technology for complete lubricant retention and contaminantĮxclusion, thereby extending bearing life - withīearing isolators are an upgrade from standard lip seals, however when one considers the total cost of the sealing system over the total life span, it is well worth it for key equipment such as p umps, m otors, g ear boxes, and split pillow blocks. The permanently assembled rotor and stator Orientation Most bearing isolators have a lubricant return designed into their respective labyrinth patterns. ![]()
