Configuration and types
BK family series
R+W offers metal bellows couplings in multiple series distinguished by hub mounting and connection type. Models include:
- BK5, BK1, BK2, BK6, BK8, BK7, BK3 - core BK bellows platforms
- BKC - clamping hub mounting
- BKM - press fit connection
- BKZ - flange mounting
- BKH - hollow shaft mounting
- BKS - conical connection
Contact Golden Bearing Company for model selection, application guidance and detailed technical information.
Mounting and design
Mounting and design classifications
BK families are classified by mounting approach: clamping hub; press fit connection; flange mounting; hollow shaft mounting; conical connection. Confirm model marking against manufacturer data for your shaft interface.
Engineering characteristics
Bellows coupling principles
A thin-walled metal bellows flexes to accommodate misalignment while maintaining angular transmission accuracy. BK designs suit applications where wind-up must be minimised compared to elastomer alternatives.
