How Long Is Turnaround Time?

5 to 7 days for minor repairs, and 10 to 14 days for major repairs.

What Is A Hydraulics Cylinder?

A hydraulics cylinder is a mechanism that is used to give linear motion and force in applications that transfer power.

How Does A Cylinder Work?

A cylinder requires hydraulic fluid and pressure to function. The fluid stored in the cylinder is converted to motion by entering one side of the cylinder through a port and pushing the piston and rod. The reverse effect can be achieved by pumping fluid in to the opposite port of the cylinder. This linear motion creates the necessary movement of the machinery or equipment.

What Are The Main Types Of Hydraulics Cylinders?

There are three most common types of hydraulics cylinders:

Tie-rod cylinders are not as strong as welded cylinders. They use one or multiple tie-rods to provide extra stability to the cylinder. These rods are mainly installed on the exterior of the cylinder and carry most of the load.

Welded cylinders offer more in the terms of customisation and strength. End caps are welded in place to close the case of the cylinder. Welded cylinders often have a narrow body and shorter overall length, enabling them to fit better in to tight spaces in machinery.

Telescopic cylinders are multi-stage units that allow the cylinder’s stroke to be longer than a normal cylinder. In this case, the piston rod is also used as a piston barrel and a second piston rod is used for the consecutive barrel.

What Are The Differences Between Tie-Rod Cylinders And Welded Cylinders?

Welded cylinders are proving to be superior to tie-rod cylinders. With a welded cylinder the end caps are welded to the case, as opposed to being secured by a tie-rod. Another factor that causes welded cylinders to be more desirable is that they are not susceptible to stretching under high pressure and long strokes, like the tie-rod counterpart is. Welded cylinders also do not require the routine maintenance that tie-rods do.

Tie-rod cylinder end-caps are larger than the diametre of the case. Therefore, with a welded cylinder thus enabling a larger bore and more lift capacity to fit in the same space as a tie-rod cylinder with a smaller bore and capacity. The only advantage of tie-rod cylinders, especially in agricultural applications, is its cheaper cost.

Current performance demands make welded cylinders the better choice when compared to tie-rod. Applications from vehicle lifts, trailers, dump trucks and snow-ploughs to heavy construction machinery and material handling equipment all benefit from the superior strength of a welded cylinder

What Does O.E.M. Mean?

An O.E.M. is the original equipment manufacturer. – work to O.E.M. specifications manufacturing or importing – everything is kept to O.E.M. specifications.

What Does ISO Mean?

ISO means “in search of”. This phrase was coined by the UN so companies would be “in search of” perfection.

As an ISO9001:2015 registered manufacturing and repairing facility, our commitment to best practices in all aspects of our business means we can be counted on for accuracy every step of the way, delivering results to the highest standards of quality, every time.

What Does MPI Mean?

MPI is the “mean point of impact”. This can be equated to a hydraulic cylinder. A precise point, associated with a target, and assigned as the center for impact of the hydraulics cylinder and to achieve the intended objective and level of destruction. Thus the wear and tear on the hydraulics cylinder.

Ductile Iron Piston/Gland Compared To Steel Piston/Gland

Ductile iron piston/gland is outdated technology. Ductile iron was originally an appealing material for cylinders because of its strength and high concentration of carbon. However, these same positive traits are also its weakness, because the hardness of the iron causes greater wear on the rod and the honed tube of the cylinder.

Cylinder manufacturers that use iron pistons do not have any seals and only have one rubber ‘O’ Ring, causing the rest of piston to create friction against the tube. Tambani Hydraulics steel pistons have high quality, polyurethane seals that greatly reduce friction inside the tube and prolongs the life of the cylinder.

Cylinders with standard ductile iron piston/glands have an average lifespan of 3 years, whereas Tambani Hydraulics cylinders manufactured using steel piston/gland combined with polyurethane seals prove to have an average lifespan up to 7 years

What Kind Of Seals Does Tambani Hydraulics Use In Its Cylinders?

O.E.M. seals or from approved suppliers.

What Is A Standard Warranty On Tambani Hydraulics Products?

Our standard warranty terms are for a 12 month or 5000 hours. This has a significant impact on our customers as this warranty is normally classed as an “as new” warranty.
