SKF uses cookies on our web site to align the information shown as closely as possible to the visitors' preferences and to tailor our web site user experience in general. Skill and cleanliness when mounting are necessary if spherical plain bearings and rod ends are to achieve maximum service life and not fail prematurely.

Bearings and rod ends should only be removed from their packages immediately prior to mounting so that they do not become contaminated. Bearing components that could have become dirty as a result of improper handling or damaged packaging should be wiped clean with a lint-free cloth. The sliding contact surfaces of spherical plain bearings are matched to provide favourable friction and wear characteristics.

Therefore, any alteration of the sliding surfaces can reduce bearing service life. Alterations in this context also include washing or exposing the sliding surfaces to solvents, cleaners, oils or similar media. All associated components should be clean and free of any burrs. Also make sure to check each associated component for dimensional accuracy before the installation process is started. Steel or plastic bands that hold together spherical plain bearing outer rings must not be removed prior to mounting.

They are positioned in an annular groove and do not protrude from the outside diameter surface. Spherical plain bearing outer rings that are axially split and bolted together must be mounted as such, without loosening the bolts. As a rule, larger bearings cannot be mounted cold because the force required to press a bearing into position increases considerably with its size.

Therefore, SKF recommends the following:. For housings, the appropriate differential depends on the degree of interference and the seat diameter. However, a moderate increase in temperature is usually sufficient.

When heating the bearing, do not exceed the temperature limit of any associated components, such as the seals. For an even and risk-free heat source, an induction heater should be used. The use of an SKF induction heater has a number of advantages.

It heats the bearing rapidly and a built-in thermostat prevents overheating. The non-metallic components, such as the seals or PTFE fabric, remain cold as does the heater itself. SKF induction heaters automatically demagnetize the bearing after it has been heated. Mounting bearings by cooling the shaft or the bearing is not recommended, as the very low temperatures required inevitably cause condensation, thus creating the risk of corrosion.

To ease the mounting of large bearings, particularly if they have been heated, it is possible to use slings and a hoist. Metal or textile slings placed around the outer ring can be used. A spring between the hoist hook and the sling also facilitates bearing handling fig.

PTFE is completely inert below this temperature but at higher temperatures from approx. The fluorine compounds released during this process are extremely toxic, even in small quantities, and can cause serious injury.

It should also be remembered that the material is dangerous to handle once it has been overheated, even after it has cooled.

Rod ends are fitted on pins and shafts in the same way as spherical plain bearings. Slight heating reduces the force required for mounting and reduce the risk of damaging associated components. When attaching rod ends to threaded rods or extension tubes fig.

It should be securely tightened against the abutment surface on the rod end or tube. These bearings are lubricated at the factory under well-controlled conditions. Introducing a foreign grease will only reduce the effectiveness of the tribological system. When mounting, do not swivel the bearing to the point where grease will be displaced from the bearing. SKF supplies a comprehensive range of mechanical and hydraulic tools as well as heating equipment for bearing mounting and dismounting.

Mounting The following tools are suitable for mounting spherical plain bearings: a mounting dolly fig.

The mounting force should never be directed through the sliding contact surfaces fig. Hot mounting As a rule, larger bearings cannot be mounted cold because the force required to press a bearing into position increases considerably with its size. Therefore, SKF recommends the following: heat the bearing before it is mounted on the shaft fig. Heat-resistant gloves should be worn when handling hot components. Rod ends Rod ends are fitted on pins and shafts in the same way as spherical plain bearings.

Note SKF supplies a comprehensive range of mechanical and hydraulic tools as well as heating equipment for bearing mounting and dismounting. Do not apply grease to the bearing. Greasing or re-greasing the bearings will compromise the maintenance-free operation of the bearings and void the service life commitment provided by SKF with the original bearing.

Bearings and rod ends requiring maintenance should be greased prior to being put into operation. With the exception of a few applications, they should be relubricated periodically. The high-strength sliding contact surfaces are phosphated and treated with a special running-in lubricant. These bearings are used primarily in applications where there are:. Lubricant starvation is a common cause of peremature bearing failure in applications where minor movements are made under heavy, constant direction loads.
