They are ideal for industries that are wet, dirty, dusty, or have lots of airborne contaminantslike sugar or flour processing facilities. Rubber blockĬomparison of compressive and horizontal shear featuresĬatalogues (Characteristics data of Bridgestone's seismic isolation bearings)īridgestone offers several types of rubber bearing and handle a wide rage of sizes from small to large diameters. A bearing isolator is an advanced sealing solution that is used to protect bearings on rotating equipment, said James Wong, the Product Manager for Bearing Isolators at Garlock. A laminated rubber bearing can be easily sheared, but its high vertical stiffness allows it to support a heavy structure such as a building. Principle of Laminated Rubber BearingĪ standard rubber block can be easily compressed and sheared because of its biaxial softness. EXP is a true non-contact bearing isolator that utilizes a dual expeller to create centrifugal. Choosing non-contacting bearing isolators can increase pump reliability. Non-contact bearing isolators for ensured lubrication reliability. This causes lubricant to escape and contaminants to enter the bearing housing, leading to bearing failure. Inpro/Seal Bearing Isolators employ multiple designs to provide permanent bearing protection on pumps and motors - increasing reliability and maximizing uptime. Contact seals tend to either wear at the point of contact or groove the shaft. The Inpro/Seal Bearing Isolators innovative non-contacting design consists of a unitized stator and rotor that form a compound labyrinth seal with no wearing. Bonding through a proprietary surface treatment prior to vulcanization, the individual rubber layers and steel shim plates are permanently bonded together between the upper and lower flanges. A bearing isolator installed on a process pump. Special Characteristics of Bridgestone MRB Cover rubber the outer cover protects rubber laminations against ultraviolet rays and ozone exposure that deteriorate rubber. Vertical rigidity assures the isolator will support the weight of the structure, while horizontal flexibility converts destructive horizontal shaking into gentle movement. The Seismic Isolating Rubber Bearing consists of alternating laminations of thin rubber layers and steel plates (shims), bonded together to provide vertical rigidity and horizontal flexibility.

Parker provides ProTech in many standard designs and custom designs.New Structure Technology - "Seismic Base Isolation System", proven during large-scale earth tremors Buy high quality Bearing Isolator by Expert Engineering. The ProTech 360 is designed for flooded oil and oil mist applications, and the Millennium profile is a metallic isolator that is unitized without internal o-rings or locking rings. The bearing isolator assembly comprises a retaining member (72), a radial wave spring (74), and a nonresilient bump stop member (130), all preferably of a one-piece steel construction. Instead of an internal o-ring protection. A bearing isolator assembly (70) suitable for use with straight roller and with ball bearings (20) is provided. Parker’s labyrinth technology provides contaminant exclusion. Bearing isolators with conventional labyrinth seal designs provide only limited airborne contaminant protection. ProTech has excellent chemical resistant seals that perform well in high speed and high-temperature environments. With Inpro/Seal Bearing Isolators you can reduce maintenance costs and double the lifetime of your rotating equipment. Parker’s ProTech bearing isolator is the “ultimate in bearing protection,” designed for zero lubricant leakage and the total exclusion of contaminants.
