Bearing Isolation & Protection
A cost-effective upgrade to improve the reliability of your rotating equipment.
Bearing Isolation Protection
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 essential to prevent premature degradation from occurring.
At AVT Reliability®, we use high-performance bearing isolators LabTecta® and MagTecta™ manufactured by our sister company, AESSEAL®. These advanced systems feature patented technology designed to prevent the ingress of water and contaminants, offering protection rated up to IP69K for demanding environments.
LabTecta®LabTecta® bearing isolators feature a non-contact design that eliminates shaft wear while providing excellent sealing performance. These isolators prevent particle ingress into the bearing housing and offer high ingress protection, with IP66 as standard and up to IP69K for more demanding conditions. Suitable for a wide range of rotating equipment, LabTecta® is ideal for pumps, motors, turbines, and plummer blocks. |
MagTecta™MagTecta™ isolators use magnetic energy and precision contact faces to protect bearings from external contaminants and lubricant leakage. This advanced sealing solution performs reliably in demanding environments. MagTecta™ is particularly suitable for oil mist systems and is also effective in a broad range of industrial applications where bearing protection is essential. |

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 | LabTecta® MG 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 product: LabTecta® ST 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. This product uses Aflas® ‘O’ rings which are resistant to temperature and steam. |
Plummer and Pillow Block Bearing IsolationRecommended 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. |
Pump Bearing Isolation and Protection
Recommended 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.
