R+W BKL bellows couplings
Technical overview of R+W BKL bellows couplings for engineering discovery and identification.
R+W BKL bellows couplings
R+W BKL series zero-backlash bellows couplings use two clamping hubs concentrically mounted to a flexible stainless steel bellows. Golden Bearing Company supplies BKL lines as R+W Germany dealer/stockist.
BKL-2 and BKL-3 sub-series
Design characteristics
BKL couplings are absolutely backlash-free due to friction clamped connection. Brief overloads up to 1.5x rated torque are acceptable per manufacturer data - not a continuous duty rating.

BKL size range
Select a catalogue size or sub-series variant for engineering data and quotation.
Common questions
They are related R+W bellows coupling variants with different assembly lengths and flexibility. Confirm model marking or send application duty for catalogue cross-reference.
Bellows couplings are commonly used on encoder and feedback shafts. For compact encoder-specific designs, also review R+W MK miniature couplings.
