Bearing Isolation & Protection

Resolve bearing failures caused by ingress of oil, water or particles.

Advanced bearing isolators can provide ingress protection up to IP69K keeping bearing oil contamination free even in the most arduous environments.

 

Bearing Protection

The very best in bearing isolation products, LabTecta® and MagTecta™, are manufactured and supplied by our sister company AESSEAL®. These solutions are designed to protect bearings against contamination, lubricant loss and premature failure across a wide range of industrial applications.

LabTecta®

The LabTecta® range features a non-contacting design that provides the highest levels of ingress protection against foreign bodies entering the bearing housing.

Suitable for pumps, motors, steam turbines and pillow or plummer blocks. ATEX hazardous area certification available.

  • Non-contacting bearing isolator
  • Maximum ingress protection
  • Wide application range
  • ATEX certification available
MagTecta™

MagTecta™ features magnetically energised contacting faces to prevent ingress and lubricant loss.

Especially suited for oil mist applications, it is a non-wearing isolator requiring no routine maintenance.

  • Magnetically energised faces
  • Ingress and lubricant loss protection
  • Ideal for oil mist systems
  • Maintenance-free design



Product range and applications

Achieve increased equipment reliability with no routine additional maintenance by upgrading your rotating equipment with AESSEAL® bearing protection solutions, supported by the application expertise of AVT Reliability.

Gearbox bearing protection
Gearbox bearing protection & isolation

Gearbox lubricants must remain free from contamination to ensure reliable operation. Bearing protection can be installed on new gearboxes or as part of a reliability upgrade for both flooded and non-flooded applications.

AESSEAL® bearing protectors, combined with the expertise of AVT Reliability engineers, provide a robust and proven solution.

Products of choice

  • LabTecta® 66FS, designed to seal oil flooded bearing chambers
  • LabTecta® OP for gearboxes, cost effective upgrade solution

Electric motor bearing protection
E-motor bearing protection & isolation

More than half of electric motor failures are caused by bearing damage due to particulate or moisture contamination. Dedicated bearing protection prevents ingress and supports long-term reliability.

Solutions are available to meet IEEE 841-2009 requirements and can be combined with optional AEGIS® grounding rings for variable frequency drive applications.

Products of choice

  • LabTecta® M, flush mount electric motor design
  • LabTecta® MG, flush mount design with grounding ring

Plummer block bearing protection
Plummer / Pillow block bearing protection & isolation

Larger alignment tolerances in plummer and pillow block applications make bearing protection more challenging. The LabTecta® design specifically addresses these conditions.

A unique two-piece stator provides self-alignment while maintaining constant pressure on the static elastomer, ensuring effective sealing across the full range of movement.

Products of choice

  • LabTecta® 66PD, positive sealing via constant elastomer pressure

Pump bearing protection
Pump bearing protection & isolation

Optimise pump operating conditions and improve bearing life with non-wearing bearing protectors offering sealing performance up to IP69K/IP66.

Pump bearing protection can be installed during overhaul, repair or as part of a
reliability upgrade.

Products of choice

  • LabTecta® OP for pumps, cost effective upgrade solution

Steam turbine bearing protection
Steam turbine bearing protection & isolation

Steam turbines present unique sealing challenges. Traditional carbon ring seals wear over time, allowing high temperature steam to migrate toward bearing housings.

LabTecta® ST bearing protectors are designed specifically for steam turbine applications, incorporating high temperature sealing, steam deflection and Aflas® O-rings to manage thermal expansion.

Products of choice

  • LabTecta® ST, advanced protection against steam ingress

Product range and applications

AESSEAL® bearing protection solutions improve reliability across a wide range of rotating equipment.

Gearbox applications

LabTecta® solutions protect gearbox lubricants from contamination.

Electric motors

Bearing protection designed to prevent contamination and moisture ingress.

Plummer & pillow blocks

Self-aligning bearing protection for challenging applications.

Pumps

Non-wearing bearing protection to extend pump life.

Steam turbines

High temperature bearing protection to prevent steam ingress.
