Bearing Isolation & Protection
A cost-effective upgrade to improve the reliability of your rotating equipment.
Contamination of bearing oil due to water or particle ingress can lead to bearing damage and, ultimately, rotating equipment failure. Reliable bearing isolation and protection are important to prevent premature degradation from occurring.
Bearing isolation products
At AVT Reliability® we use high-quality advanced bearing isolators, LabTecta® and MagTecta™, manufactured and supplied by AESSEAL®, our sister company. These innovative products have patented features which can keep bearing oil free of water and contaminants, preventing ingress up to IP69K in a wide range of different working environments.
LabTecta®
LabTecta® bearing isolators are a non-contact design so will not cause any wear on the machine shaft. These bearing isolation products prevent particles from entering the bearing housing and have a high level of ingress protection, with IP66 as standard, up to IP69K.
The LabTecta® range of bearing protection is suitable for many applications, including general-purpose pumps and motors as well as turbines and plummer blocks.
MagTecta™
MagTecta™bearing isolators use magnetically energised contact faces which protect bearings from both external contamination and loss of lubrication.
The MagTecta™ range can be used for a range of applications and is particularly good for oil mist (pure mist) applications.
Bearing protection product applications
All LabTecta® and MagTecta™ products are a cost-effective way to improve the reliability of your rotating equipment by isolating and protecting the bearings. Once you have upgraded your equipment with these products there is no further routine maintenance required. Our engineers at AVT Reliability® all have the expertise to advise on the best products for you and are trained to fit them to your equipment.
Pump bearing isolation and protectionRecommended product: LabTecta® OP Pump bearings are extremely important for the efficient running of your machinery. Optimising your pump by protecting the bearings with a non-wearing bearing isolator is a cost-effective way to upgrade your machinery. The LabTecta® range can be installed as part of a reliability upgrade, an overhaul or repair.

Gearbox bearing isolation and protectionRecommended products: LabTecta® 66FS | LabTecta® OP Gearbox lubricants need to be free of contamination so that they always operate reliably. Bearing protection products can be installed either when the gearbox is new or as part of a reliability upgrade. The AESSEAL® LabTecta® 66FS is the ideal product for sealing oil-flooded bearing chambers, while the LabTecta® OP is a cost-effective gearbox bearing protection upgrade.

Electric motor bearing isolation and protectionRecommended products: LabTecta® M (Flush Mount Electric Motor Design) | LabTecta® MG (Flush Mount Electric Motor Design with grounding ring) Electric motors require specifically designed bearing protection products to ensure they are suitable for variable frequency drives and that they meet IEEE 841-2009 requirements. More than half of e-motor failures are a result of moisture or particulate contamination of the bearings, so a flush mount electric motor design bearing isolator will prevent this ingress from occurring.

Steam turbine bearing isolation and protectionRecommended products: LabTecta® ST – The most effective solution to prevent steam ingress The high temperatures and steam involved in steam turbines raise unique bearing protection issues. Over time, the carbon ring seals usually fitted in these turbines start to wear and can result in high temperature, high-velocity steam reaching the bearings. The LabTecta® ST is a very effective bearing protector that prevents steam ingress. It is designed to withstand high temperatures and deflect steam, whilst also having extra clearance to allow for thermal expansion. In addition, this product uses Aflas® ‘O’ rings which are resistant to temperature and steam.

Plummer and pillow block bearing isolation and protectionRecommended product: LabTecta® 66PD Pillow and plummer blocks have a larger shaft alignment clearance variance so bearing protection requires a specifically designed product to overcome the challenges this causes. The recommended LabTecta® 66PD bearing isolator is a two-piece design which can self-align to both the bearing block and the shaft. Through continuous pressure, it creates a positive seal on the static elastomer while the machinery is in motion.
