T.40 Tyre Coupling Hub (Pilot Bore)
The T.40 Tyre Coupling Hub (Pilot Bore) functions as a core structural element within highly flexible elastomeric tyre coupling setups. Supplied with a raw factory pilot bore, this hub gives your engineering team full control to custom-machine internal bore diameters and standard keyways explicitly dimensioned to clear your engine, gearbox, or industrial pump shafts. Its heavy-duty casting handles continuous torsional loads, effectively dampening severe shocks and accommodating extreme parallel, angular, and axial shaft misalignments.
Product Features & Specifications
- Model Size: T.40 Framework
- Mounting Configuration: Pilot Bore raw finish, facilitating flexible post-factory optimization.
- Shaft Integration: To adapt this hub to your machinery, specify custom boring and keying sizes through our dedicated In-House Machining Services.
- Order Information Note: To ensure accurate warehouse packing, please confirm your required structural flange layout style upon checkout (i.e., F/F, F/H, H/H style arrangements or basic unmachined pilot bore).
