Applications Of Zinc-Aluminum Alloy Bushings

Zinc-aluminum alloy bushings (especially high-aluminum zinc-based alloys such as ZA27, ZA27-2) are widely used in various industrial fields due to their high strength, wear resistance, lightweight, low cost, and self-lubricating potential.

Main Application Scenarios

Mining Machinery: Used in crusher eccentric sleeves, vibrating screen bearing seats, conveyor roller bearings, etc., to withstand ore impact and abrasive wear. Their non-sparking characteristics make them suitable for explosion-proof environments in coal mines.

Agricultural Machinery: Such as tractor suspension mechanisms, harvester reel wheel bearings, seeder opener shaft sleeves, etc., operating in dusty and humid environments, where the maintenance-free advantage is significant.

Construction Machinery: Small excavator slewing bearings, loader articulation points, concrete mixer support wheels, etc., where lightweight helps lower the overall center of gravity and improve stability.

General Heavy Equipment: Guiding sleeves, bearing seats, slide plates, etc., in injection molding machines, hydraulic presses, and cranes, replacing traditional copper alloy bearings.

Low-Speed Heavy-Duty Transmission Components: Such as worm gears and drive nuts, utilizing their excellent anti-galling and wear resistance.

Simple Molds: Used in punching dies, deep-drawing dies, bending dies, etc., suitable for small batch production or trial production of new products.
