Overview
Hydraulic Rod End Bearing HCR20U Product Overview
HCR20U-25 is a metric hydraulic-cylinder rod end bearing for compact cylinder-side linkage assemblies. It combines a Forged, heat-treated C45 / AISI 1045 steel 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 M16x1,5 thread.
The size-25 configuration has a 56 mm outer diameter, 20 mm inner ring width, 23 mm bearing width, 50 mm medium length, 25 mm diameter, 17 mm thread length, 80 mm overall length. Published performance values are 37-100 μm internal clearance, 48 kN dynamic load rating, 72 kN static load rating, 46 mm collar diameter, 7° tilt angle, 25 Nm torque, and approximately 470 g weight.
Hydraulic grease nipple to DIN 71412. The stated operating range is -50°C to +150°C. A GE..LO spherical plain bearing can be supplied on request, subject to the selected size and application. Confirm the cylinder geometry, side-load condition, clearance, lubrication access, and final material requirements against the HCR20U specification before production release.
