R+W BK2 Metal Bellows Coupling
R+W BK2 standard-series metal bellows coupling with clamping hubs for precision servo and spindle drives requiring low backlash.
Model overview
R+W BK2
R+W BK2 standard-series metal bellows coupling with clamping hubs for precision servo and spindle drives requiring low backlash.
Design and construction
Engineering characteristics
BK2 is part of the R+W BK metal bellows platform with clamping-hub mounting. Clamping-hub metal bellows couplings use stainless steel bellows elements for angular compensation with low wind-up. BK2 belongs to the standard BK series, distinct from the economy BKL line.
Selection guidance
Choosing and specifying
- Confirm R+W BK2 model designation against equipment nameplate or drawing.
- Compare with BKL economy bellows when catalogue size, envelope or economy-series supply is relevant.
- Define shaft bore, torque duty, speed and misalignment for R+W catalogue review.
- Do not assume BK2 and BKL share identical dimensions, torque ratings or bore data because the product image is similar.
Applications
Typical use context
Servo motor connections, ball screw drives, encoder interfaces and precision machinery where standard BK metal bellows coupling duty applies.

Common questions
BK2 is a standard-series R+W metal bellows coupling within the BK platform, typically used with clamping-hub mounting for precision rotating shaft connections.
BK2 is part of the standard BK metal bellows series. BKL is the R+W economy zero-backlash bellows line with its own catalogue sizes and dimensional data. They are separate engineering identities.
Both are clamping-hub metal bellows designs with legitimately similar visual construction. Golden Bearing uses a governed shared product image while preserving separate BK2 and BKL model identities and catalogue references.
No. Similar appearance does not imply interchangeable torque, bore, speed or dimensional ratings. Select and quote the correct R+W model designation.
