40x80x24.2mm BMB-6208 080S2 UB108A Sensor Bearing Encoder Units BMB-6208 080S2

MB-6208/080S2/UB108A and BMB-6208/080S2/UB008A are integrated encoder sensor bearing units upgraded based on standard 6208 deep groove bearing dimension (40×80mm). The core difference lies in signal cable length and terminal configuration:

• MB-6208/080S2/UB108A: 571mm built-in sensor cable, standard 2-channel square wave signal, long cable version for distant wiring
• BMB-6208/080S2/UB008A: 546mm built-in sensor cable, compact short cable design for narrow motor housing installation

This bearing integrates rolling bearing and magnetic rotation sensor as one unit, real-time capture rotational speed, rotation direction and pulse signals without extra external encoders. Adopt C3 enlarged radial clearance, single-side contact rubber seal, non-metallic polymer cage, stable continuous operation under medium radial loads. Widely used for servo motors, textile printing main drive motors, automation spindle motors, packaging machinery drive shafts and industrial motor speed closed-loop control system replacement.

Full technical CAD drawings, sensor wiring diagram and motor fitment list available upon request

• All-in-one bearing + encoder integrated design, save installation space, eliminate assembly tolerance error between separate encoder and bearing, improve speed detection accuracy
• Two cable length options (546mm / 571mm) match different motor housing depth and wiring layout requirements, direct interchangeable base bearing structure
• C3 oversized internal clearance offsets thermal expansion of high-speed running motor shafts, effectively prevent bearing seizure under continuous heat accumulation
• Mirror superfinished raceway & steel ball surface reduce rotation friction torque, guarantee low vibration, low noise stable operation for long-term closed-loop control
• Single-side contact rubber seal blocks motor workshop dust, cutting fluid and moisture, avoid sensor internal circuit pollution and bearing premature wear
• Through-hardened GCr15 bearing steel with stable heat treatment, strong anti-fatigue performance, adapt 24-hour uninterrupted industrial motor operation
• Support custom pulse number, cable length, terminal connector type, OEM laser marking and neutral anti-rust vacuum packaging for automation equipment wholesalers

Reduce motor speed detection failure rate and cut overall equipment maintenance downtime
