Overview
Hydraulic Rod End Bearing HCR25D Product Overview
HCR25D-25 is a metric hydraulic-cylinder rod end bearing for compact 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 M18x2 thread.
The size-25 configuration has a 56 mm outer diameter, 20 mm inner ring width, 23 mm bearing width, 65 mm medium length, 28 mm diameter, 30 mm thread length, 95 mm overall length. Published performance values are 37-100 μm internal clearance, 48 kN dynamic load rating, 76 kN static load rating, 48 mm collar diameter, 8° tilt angle, 20 Nm torque, and approximately 650 g weight.
No external lubrication fitting; grease hole machined in the housing. 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.
