SP3 Metal Bellows Couplings
Description
Using additional balancing, SP3 bellows couplings allow for much higher operational speeds than the typical 10,000 rpm. Available sizes range from 60 to 500 Nm, couplings have an integral clamping ring system, with the base hub components held to a very high level of concentricity between the two respective bores during the assembly process.
The external clamping ring provides symmetrical construction even when it comes to the small amounts of deformation during clamping compression onto the shafts. Inconsistencies, even small ones, are contained to the ring itself, with the coupling straightness remaining highly accurate during installation.
Specs
- Very high balancing quality due to symmetrical design
- High operating speeds
- Extremely smooth running
- Bellows: high-grade stainless steel
- Hubs and clamping ring: steel
- Two precision-machined clamping ring hubs are mounted concentrically to flexible bellows. Brief overloads of up to 1.5x the rated torque are acceptable.
- Overall shaft/hub tolerance: 0.01 to 0.025 mm
