Pillow Block Bearing Protection
Increase Pillow Block Reliability and Cost Savings
The Importance of Bearing Protection
Pillow blocks are an important component to the rotating process as they support the shaft on a variety of rotating and power transmission equipment. They are designed to operate many years, yet they consistently cause downtime due to bearing failure from contamination ingress or lubrication loss.
Ineffective Seals Lead to Downtime
Pillow blocks commonly use LER or LOR rings to seal the bearings. These simple gap seals rely on a tight clearance between the seal and shaft as the sealing mechanism. Dirt and water particulates can easily pass through the seal, contaminating the bearings along with allowing lubrication to escape to atmosphere.
In some instances, grease is used to purge the seal, creating a barrier. Grease purged seals are labor intensive and unreliable as the seals need to be constantly greased or else become ineffective in a short time.
Increase pillow block reliability and mean time between repair (MTBR) with permanent bearing protection.
A Permanent Sealing Solution
The Inpro/Seal Bearing Isolator increases pillow block reliability with permanent bearing protection against contamination ingress and lubrication loss, significantly increasing mean time between repair (MTBR) and decreasing maintenance costs. The unique non-contacting design has no wearing parts, lasting the lifetime of your equipment.
