Overview
The Falk 1203268 gear coupling sleeve is a Type G20 double engagement component from the Lifelign® gear coupling family. This large flanged sleeve provides double engagement design suitable for demanding industrial applications. Manufactured from durable steel, the 1040G20 designation indicates the coupling size and type. The flanged sleeve design enables secure, bolt-on assembly with matching hubs while maintaining precise alignment and torque transmission.
Key Features
- Type G20 Double Engagement — Accommodates up to 3/8° of misalignment while transmitting power and torque
- Flanged Steel Construction — Durable steel material resists wear and provides extended service life
- Gear Mesh Design — Designed to provide a mechanical connection between rotating shafts using gear mesh to accommodate inherent misalignment
- Lubrication Provisions — Operates within ambient temperatures of –30°F to 200°F (–34°C to 93°C) when lubricated bi-annually
- Integrated Seal Rings — Includes seal rings mounted on shafts before flex hubs for protection
