Technical Information
Hydraulic cylinders with Yale ChroMo-Design

Chromium-molybdenum steel

Yale hydraulic tools are designed for professional operation. A tool is only as good as its basic material. Therefore our cylinders are designed from high quality chromium-molybdenum steel and heat treated. This unique basic material gives Yale hydraulic cylinders a distinctly higher strength in the elastic range, thus providing a considerably longer service life, primarily when hydraulic cylinders are subjected to inevitable eccentric loads.

Double bronze bearings

Practice has shown that hydraulic cylinders used as a tool in workshops or on construction sites are frequently subjected to eccentric loading. Yale hydraulic cylinders are provided with double bronze bearings on the plunger, which minimises friction between a plunger and body during lateral loading.

Hard-chromium plated piston

Offers excellent protection against mechanical damage and corrosion. Excellent sliding characteristics in conjunction with the upper bronze bearing in the stop ring.

Metric Mounting threads and standard parts

To facilitate the installation of hydraulic cylinders in jigs and fixtures and auxiliary structures. The metric standard throughout the entire series simplifies service operations and repairs.

Stop ring carries full pressure

As a safety factor the stop ring on all Yale hydraulic cylinders carries the full load even under maximum operating pressure.

Delivered “ready to use”

Yale Hydraulic cylinders are delivered ready to use incl. female coupler half, hardened sadddle and mounting threads; larger cylinders come with carrying handle or transportation lugs. This also applies to customised combinations which are always supplied ready assembled.
