BMB-6209 080S2 UH108A Encoder Bearing Automotive Bearings For Induction Motor , 45x85x25.2mm
BMB-6209/080S2/UH108A is an integrated magnetic encoder sensor bearing unit upgraded on standard 6209 deep groove ball bearing structure, specially matched for electric forklift traction drive motors, also compatible with heavy-duty servo motors, textile main drive spindles and logistics AGV closed-loop speed control systemsSKF 集....
This all-in-one unit combines rolling bearing, impulse ring and magnetic induction sensor, eliminating separate external encoder installation. It collects real-time rotational speed, rotation direction and 90° phase-shift quadrature pulse signals without extra assembly fixtures. Equipped with outer ring circlip positioning groove for axial limit, single-side RS1 contact rubber seal and C3 enlarged radial clearance to avoid seizure caused by thermal expansion under long-time heavy-load motor operation. Built-in sensor outputs 80 pulses per revolution with stable anti-interference performance against workshop oil mist, metal dust and humidity, widely used for forklift motor overhaul and industrial automation equipment aftermarket replacement.

Only the built-in sensor signal cable plug pin definition differs; bearing mechanical dimensions, clearance, load and pulse parameters are fully consistent and interchangeable. UH108A is equipped with dedicated forklift motor waterproof plug.
Not universal. This unit integrates magnetic sensor with total assembly width of 25.2mm, standard 6209 bearing width is only 19mm, and it has unique outer ring circlip positioning groove; only matches motors originally equipped with BMB series encoder bearing unit.
Forklift speed display loss, vehicle acceleration jitter, closed-loop control out of sync, distorted pulse signal waveform, abnormal buzzing noise during motor operation, sensor cable aging and oil corrosion damage. Replace the whole encoder bearing unit to restore normal speed feedback control.
