Axial Shaft Movement

Bearing protector designs that are engineered to accommodate axial shaft movement.

• No axial sliding movement on the shaft means the rotary drive integrity is not compromised
• Superior protection against contamination ingress as the rotor to stator seal integrity is not affected by the axial movement
• Standard LabTecta 66AX design accommodates ± 0.100” (± 2.5mm)
®
of axial movement; however, it can be designed to take any amount of
movement that the application dictates
• Unique dual rotor design with drivelock for superior reliability

Competitor labyrinth seal technology in
axial movement application.

Innovative Technology
The LabTecta 66AX design uses a unique sliding rotor that
®
allows the seal to absorb axial movement internally. With
this rotor design no axial sliding movement on the shaft
exists that can cause shaft damage, drive-ring damage or
allow contamination to pass under the drive ‘O’ ring.

The LabTecta 66AX provides superior reliability by utilizing
®
double drive rings to provide a secure grip on the shaft,
reducing the chance of shaft slip and a dual-rotor design Negative Movement Positive Movement
with a secure drivelock to ensure both rotors continuously
follow the shaft.
