How the BMB-6202-032S2-UB008A model number is decoded

The load-carrying envelope is a 15 mm bore by 35 mm outside diameter in a 11 mm width, and the catalogue ratings for the bearing inside are C 7.8 kN, C0 3.75 kN and Pu 0.16 kN. Two 90°-shifted output signals at 32 pulses per revolution, period accuracy ±3% and phase tolerance ±30°; the maximum mechanical speed is 13000 r/min. The C/C0 ratio of 2.08 is typical of a sensor bearing unit that shares the ordinary bearing raceway with the encoder track, so radial loads are carried by the same rolling elements that position the sensor ring. The unit weighs 62 g over its 15/35/11 mm envelope and ships with a 525 mm cable terminating in a free cable end; within this 32-pulse size the connector is the sole electrical option. The 32-pulse output reaches 6933.333 Hz per channel at the 13000 r/min mechanical limit, equivalent to 11.25° of rotation per pulse, so the receiver must be able to accept that bandwidth. with a 15 mm bore this is a small sensor bearing unit; the 35 mm outside diameter keeps the housing bore within ordinary machined tolerances BMB-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/B block means a glass-fibre reinforced PA66 ball cage, chosen for quiet running and resistance to the temperature swings of a rotor-mounted unit. typical applications include wind turbine yaw and pitch feedback, machine-tool spindle position monitoring and industrial automation axis control this unit is commonly specified for wind turbine yaw and pitch feedback and machine-tool spindle position monitoring, where rotor position and speed sensing with a 32-pulse signal fits the controller's input in industrial automation axis control the integrated bearing carries the shaft load while the sensor ring supplies the signal; the 62 g mass keeps the rotating inertia low the embedded bearing shares its grease charge with the sensor assembly, so both the lubricant specification and the temperature range must be respected together mounting the unit on a rotor with excessive unbalance or axial play loads the sensor ring unevenly and shows up as a periodic error in the signal 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

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• the embedded bearing shares its grease charge with the sensor assembly, so both the lubricant specification and the temperature range must be respected together
• mounting the unit on a rotor with excessive unbalance or axial play loads the sensor ring unevenly and shows up as a periodic error in the signal
• 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
