Heavy-Duty Grinding Spindle
190XDJ08G52.5 HC100
Ultra-powerful HC100 flange spindle with 500mm wheel capacity. 52.5 kW power, 62.7 Nm torque for the most demanding heavy grinding operations -- large bearing races, heavy cylindrical grinding, and industrial-scale material removal.
190XDJ08G52.5 HC100 Heavy-Duty Grinding Spindle
The 190XDJ08G52.5 HC100 is our most powerful heavy-duty grinding spindle, purpose-built for the most demanding industrial grinding applications. With an extraordinary 52.5 kW of continuous power at 8,000 r/min and a massive 62.7 Nm of torque, this spindle delivers unprecedented material removal capability for heavy grinding operations, large bearing race grinding, and heavy cylindrical grinding where maximum power and rigidity are non-negotiable.
Equipped with a heavy-duty HC100 large grinding wheel flange interface and P4/P2 hybrid angular contact ball bearings in a tandem-O configuration optimized for extreme grinding forces, the 190XDJ08G52.5 HC100 achieves runout accuracy of 0.001mm or less even under the most demanding cutting loads. The advanced oil-air micro-lubrication system ensures reliable bearing performance across the complete operating range. The high-capacity spiral water-cooling jacket maintains stable thermal conditions during extended heavy grinding cycles. With a maximum grinding wheel diameter of 500mm and a massive 190mm housing, this spindle is the ultimate solution for the heaviest industrial grinding tasks. Dynamically balanced to G0.4 per ISO 1940-1 and rated IP54, the ~220 kg weight provides maximum rigidity and vibration damping for industrial-scale grinding operations.
