UK Series 1:12 Tapered Bore Insert Bearing UK205 UK206 UK207 Wide Inner Spherical Bearing With H Adapter Sleeve

UK Series insert bearings Product Features

1:12 tapered inner bore design, install with H adapter sleeve, uniform circumferential extrusion force, no scratch or indentation on shaft surface, effectively protect transmission shafts.
Wide inner ring structure increases contact area with adapter sleeve, improves overall load capacity and anti-loosening performance under long-term heavy vibration.
Spherical outer ring self-aligning design allows ±2° angular misalignment compensation, eliminates abnormal noise and premature raceway spalling caused by housing assembly deviation.
Standard SL double composite lip seal with outer metal slinger, multi-stage barrier against mud, crop dust and water splashing, suitable for harsh farm and construction working conditions.
Pre-filled high-temperature lithium complex grease, equipped with external grease nipple for periodic supplementary lubrication; full hardness and noise inspection before shipment, stable mass production delivery.
