Hydraulic Cylinder Rod Ends

A hydraulic cylinder rod end is a rod end bearing — a spherical plain bearing in a forged or cast eye housing — that connects a cylinder piston rod or base to the machine while absorbing misalignment. SYZ supplies 7 metric HCR series, 96 sizes from 10 to 200 mm, in forged St 52-3, C45 and GS400 cast housings.

Application Overview

Rod End Bearings for Hydraulic Cylinder Linkages

Hydraulic cylinder rod ends transfer force between the piston rod and the machine linkage while allowing the angular movement created during the stroke. The HCR range is organized around the variables that matter in a cylinder connection: bore size, housing material, race and inner-ring material, grease access, misalignment and available installation space.

Each HCR series page carries the published size table for that family, including bore, load data, tilt, weight and other available dimensions. Use the series cards below as the first filter, then confirm the exact size against your drawing and operating conditions.

Forged and Nodular Housings

The catalogue includes forged St 52-3, forged C45 / AISI 1045 and GS400 nodular cast iron housing options by series and size.

Metric Selection Data

Every HCR series page links to a size-specific table with dynamic/static load, tilt and weight data. Confirm the working load and joint geometry before release.

Lubrication and Service

Some families include DIN 71412 grease-nipple provisions; availability is series- and size-dependent. The HCR20U family also lists a GE..LO bearing option on request for applicable sizes.

Selection Guide

What to Confirm Before Ordering

1. Bore and Thread

Start with the cylinder rod or pin interface. Confirm metric bore, thread direction and the available nut, washer or locking arrangement.

2. Load and Motion

Compare the catalogue dynamic and static load data with the cylinder force, duty cycle, oscillation and any shock loading in the linkage.

3. Housing and Lubrication

Select forged steel or GS400 according to the series and geometry. Confirm grease access, temperature and contamination controls for the actual installation.

Applications

Built Around the Cylinder Connection

HCR series are intended for metric hydraulic-cylinder linkage decisions where the bore, load, tilt and housing construction must be checked together. Typical review requests come from mobile equipment, agricultural machinery, construction equipment and industrial cylinder assemblies; final application suitability should be confirmed from the size data and drawing.

For an existing connection, send the old part number or a clear photo with bore, thread, overall length, load and articulation. This gives engineering a usable starting point for matching.

Manufacturing & Quality

Specification-Led Supplier Support

The HCR catalogue records housing material, bearing material, lubrication provision, static/dynamic load, tilt and weight at the series or size level. SYZ can review drawings, samples and replacement parts for OEM and wholesale sourcing.

Do not assume a general ISO or DIN compliance claim from a material or grease-nipple reference. DIN 71412 in this range identifies the grease-nipple provision where listed; request the exact drawing and documentation for your application.

FAQ

Hydraulic Cylinder Rod End Questions

What is the difference between a hydraulic rod end and a standard heim joint?

A hydraulic rod end is selected for a cylinder connection and is typically reviewed with metric bore, cylinder-side geometry, load data, tilt and housing construction. A standard heim joint is a broader threaded linkage component; the correct substitute depends on the load, articulation and mounting design.

Which housing material should I choose?

Choose from the material options published for the required series and size: forged St 52-3, forged C45 / AISI 1045 or GS400 nodular cast iron. The decision should consider load, shock, environment, geometry and the exact size drawing.

Do HCR rod ends need greasing?

Lubrication provisions are series- and size-dependent. Several HCR families list a DIN 71412 grease-nipple provision, while other sizes use a different or no external provision. Verify the selected product page before setting a service interval.

What temperature range is listed?

The common catalogue range is −50°C to +150°C. Actual application limits also depend on load, speed, oscillation, lubricant and surrounding seals; request a review for conditions outside the published range.

Can you match my existing cylinder rod end?

Yes. Send the old part number or a photo plus bore, thread, overall length, load, articulation, quantity and any drawing. SYZ can compare it against the HCR series and confirm the closest available size.

What is the MOQ and lead time?

MOQ depends on the series, size and whether the order is a sample or production run. A typical production lead-time reference is 25 days after specification and order confirmation; request a current quote for the exact part and quantity.
