Overview
The Fenner 6202107 Trantorque Mini is a compact keyless bushing designed for small-diameter shaft applications requiring precise, maintenance-free mounting. Featuring a 5/16″ bore and 3/4″ outside diameter with nickel plating for corrosion resistance, this unit provides a zero-backlash frictional connection that eliminates the drawbacks of traditional keyed or splined shafts.
Key Features
- Zero-Backlash Design: Delivers a true zero-backlash shaft-to-hub connection without the operational limitations of keys or splines
- Single Hex Nut Installation: Simple, fast assembly and repositioning with no special tools or component machining required
- Nickel-Plated Steel Construction: Corrosion-resistant finish suitable for demanding industrial environments
- High Concentricity: Exceptional runout tolerance for critical timing and alignment applications
- Durable Performance: Never wears or pounds out under high-torque, bending, thrust, and radial loads
- No Maintenance Required: Friction-based locking mechanism requires no lubrication or periodic adjustment
Technical Specifications
- Bore Diameter: 5/16″ (7.94 mm)
- Outside Diameter: 3/4″ (19.05 mm)
- Material: Carbon Steel, Nickel Plated
- Installation Method: Single Hex Nut Clamping
- Bushing Type: Trantorque Mini Keyless
- Backlash: Zero
- Surface Treatment: Electroless Nickel Plating
