The ROCHMAN/Seal Bearing Isolator is a non-contacting, permanent bearing
protection device. Inpro/Seal’s patented design consists of a unitized
stator and rotor that form a compound labyrinth seal with no wearing parts –
ensuring permanent protection. The stator is typically pressed into the bearing
housing, while the rotor turns with the shaft
The ROCHMAN/Seal Bearing Isolator protects in multiple ways. Lubricant is captured in
the inner portion of the labyrinth and flows back to the bearing housing. Outside
contamination attempting to enter the bearing housing is captured in the outer
labyrinth paths and expelled through a port in the stator by centrifugal force and gravity
Protection method is to use common bearing contact seal, for example: skeleton oil seal, PTFE oil seal, magnetic oil seal, all contact seal life is limited, finally there will be a point of contact and wear and leakage, or after shaft rod scratches, cause the sealing surface wear too fast, not rise to the effective sealing Contact seal service life is short and unpredictable, it is a kind of imperfect way of sealing
Rochman seal bearing isolator is a non-contacting,non-wearing permanent bearing protection device,it’s can be provides full bearing protection. The sealing performance will not decrease with running time, It’s widely used in pump motor gearbox fan base turbine machine roller. Rolling mill roll and other type of rotary equipment. While improving the stability of the equipment, it can prolong the service life of the equipment more than twice
The bearing isolator advantage:
non-contacting,non-axis
non-wearing,zero energy consumption
maintenance free,permanent bearing protection
vapor blocking o ring designs, vapor blocking ring inhibits the free transfer of vapor contamination when the rotating equipment is cycled off.
The protection level can reach IP66
speed can reach 60m/s
reusable
