Overview
Hydraulic Rod End Bearing HCR20U Product Overview
HCR20U-70 is a metric hydraulic-cylinder rod end bearing for larger 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 M65x1,5 thread.
The size-70 configuration has a 154 mm outer diameter, 49 mm inner ring width, 55 mm bearing width, 150 mm medium length, 86 mm diameter, 66 mm thread length, 232 mm overall length. Published performance values are 55-142 μm internal clearance, 315 kN dynamic load rating, 540 kN static load rating, 130 mm collar diameter, 6° tilt angle, 210 Nm torque, and approximately 9880 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.
