Industrial Fan & Blower Power Transmission Product Benefits

Zero-Max’s OHLAs are designed to absorb radial and axial loads normally exerted on hydraulic motors and pumps  by radiator or industrial fan or blowers in mobile hydraulic equipment. This ensures premium performance while extending the lifespan of your equipment, saving on expensive replacement costs and greatly reducing operational downtime. Our OHLAs require virtually no maintenance and can handle high loads and high speed operation. Additionally, these field-proven OHLAs provide a solid, permanent mounting surface while also permitting the removal of hydraulic motors/pumps for servicing without disturbing driven gears, pulleys, or sprockets.

Zero-Max’s OHLAs also feature additional seal protection that serves as a contamination barrier to keep out dirt and other contaminants from hydraulic systems. Over 75% of Zero-Max OHLAs are customized to meet application specific requirements, with popular customizations including specialized mountings, dimensions, materials, and additional requests. Zero-Max OHLAs are durable enough to absorb radial and axial loads in demanding environments.

Additional Fan & Blower Components

CD Couplings

Our CD couplings are constructed to handle shaft misalignments and repetitive speed changes in demanding environments without sacrificing performance. CD Couplings can be paired with high speed fans to improve reliability and durability.

ETP Keyless Shaft Bushings
ETP hydraulic-based keyless shaft bushings are ideal for positioning and locking shaft components in a system and provide the best alternative to keyways and tapers.  ETP shaft bushings can be mounted and dismounted in seconds and offer hundreds to thousands of mounting cycles.

Posi-Lok® Keyless Shaft Bushings
Posi-Lok (PSL) keyless shaft bushings provide a secure shaft-to-hub connection and reduce fretting, corrosion, and backlash in production processes.
