The HK Series needle roller bearings feature a compact radial cross-section with an inner ring, ideal for applications demanding high load capacity within limited radial space. Precision-ground needle rollers guided by a machined cage ensure low friction and stable operation at elevated speeds. With a bore range from 10mm to 160mm, these bearings are widely used in automotive transmissions, industrial gearboxes, power tools, textile machinery, and general mechanical equipment where space constraints and high radial loads coexist.
