How the BMD-6206-064S2-UA008A model number is decoded

The 30 mm bore and 62 mm outside diameter carry the deep groove ball raceway while the 16 mm width houses the sensor ring; the published ratings are C 19.5 kN, C0 11.2 kN and a fatigue load limit Pu 0.475 kN. The encoder delivers 64 pulses per revolution as two output channels 90° apart, each pulse period accurate to ±4% and the phase held to within ±30°; limiting speed 7500 r/min. Because the sensor ring does not alter the ball raceway, the static-to-dynamic ratio stays at 1.741 (11.2 kN against 19.5 kN), matching the plain bearing of this size. Physically the unit is a 30/62/16 mm, 220 g assembly with a 540 mm cable ending in a free cable end; the 64-pulse electronics are otherwise fixed for the size. At the 7500 r/min limiting speed the 64-pulse track produces 8000 Hz per channel, i.e. 5.625° of shaft rotation per output pulse; check the receiving controller's input frequency range against that figure. with a 30 mm bore and 62 mm outside diameter this is a medium-size unit, suitable for standard shaft ends without custom housings BMD-6206/064S2 style designations are decoded as bearing code, pulse block and interface block — the /064 is not a part number but the number of pulses per revolution, and S2 confirms two output channels. The trailing 008A marks the free cable end variant, supplied as a plain cable tail for the customer to terminate; it is the shorter-cable option of the pair. The U/A block means a stamped steel ball cage, standard for the sizes where the higher load ratings rule out a polymer cage. typical applications include servo motor rotor feedback, textile spindle speed control and wind turbine yaw and pitch feedback this unit is commonly specified for servo motor rotor feedback and textile spindle speed control, where rotor position and speed sensing with a 64-pulse signal fits the controller's input in wind turbine yaw and pitch feedback the integrated bearing carries the shaft load while the sensor ring supplies the signal; the 220 g mass keeps the rotating inertia low the limiting speed is a mechanical limit for the embedded bearing; running above it shortens grease life long before the electronics fail period accuracy is quoted as a percentage of one pulse period — the absolute angular error grows as the pulse count falls, so compare units at equal N the sensor ring and the ball raceway share one compact unit — a bearing that is due for replacement takes the encoder signal with it, so renew both together

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• the limiting speed is a mechanical limit for the embedded bearing; running above it shortens grease life long before the electronics fail
• period accuracy is quoted as a percentage of one pulse period — the absolute angular error grows as the pulse count falls, so compare units at equal N
• the sensor ring and the ball raceway share one compact unit — a bearing that is due for replacement takes the encoder signal with it, so renew both together
