Overview
Hydraulic Rod End Bearing HCR25D Product Overview
HCR25D-80 is a metric hydraulic-cylinder rod end bearing for larger cylinder-side linkage assemblies. It combines a GS400 nodular cast iron housing with a bearing shell and inner ring made from 100Cr6 / AISI 52100 bearing steel, hardened and ground; phosphate and molybdenum-disulfide surface treatment. It uses a right-hand M90x3 thread.
The size-80 configuration has a 176 mm outer diameter, 55 mm inner ring width, 60 mm bearing width, 210 mm medium length, 125 mm diameter, 120 mm thread length, 305 mm overall length. Published performance values are 55-142 μm internal clearance, 400 kN dynamic load rating, 890 kN static load rating, 168 mm collar diameter, 6° tilt angle, 300 Nm torque, and approximately 16000 g weight.
Hydraulic grease nipple to DIN 71412. The stated operating range is -50°C to +150°C. Confirm the cylinder geometry, side-load condition, clearance, lubrication access, and final material requirements against the HCR25D specification before production release.
