SKF Vibracon adjustable chocks
The chocking solution for rotating equipment
SKF Vibracon chocks are self-leveling and provide the option to reduce profile height. They allow easy, accurate mounting of all types of rotating equipment to base frames and either steel or concrete foundations. They accommodate the angular difference (up to 4°) between machine and mounting base without the need to machine the base or install epoxy resin chocks.
The chocks eliminate soft foot- and can lower the cost of equipment foundations – whether they are designed-in or retrofitted.
SKF Vibracon chocking solutions offer you the advantages of:
- A high load capacity
- A broad adjustment range
- An optimized load path through the product
- An optimized bolt/Vibracon combination
- Reduced chock height across the entire range
SKF Vibracon chocks can save costs and raise performance in many industries, including:
- Food & beverage
- Pulp & paper
- Oil & gas
- Marine & offshore
- Railways
- Power generation – including renewable energy
- Agriculture
- Clean room application
Typical SKF Vibracon applications are:
- Gas and diesel engines
- Compressors
- Electric motors
- Gearboxes
- Generators
- Pumps and fans
- Bearing housings
- Turbines
- Other critical rotating machinery
Adjustable chocks
Carbon steel chocks
SKF Vibracon
E-CS series
SKF Vibracon adjustable chocks can satisfy a range of technical concerns, as they are available in a number of configurations and materials. Chocks made of carbon steel are recommended for indoor use.
They provide a cost-effective solution for standard applications, while offering reliable performance in environments such as on the factory floor. Applying additives at the mating surfaces provides initial protection – both before and during installation – and prevents parts from seizing when they are adjusted.
The SKF Vibracon is available in different materials to meet the need of your application, even those in the harshest environments.
Surface treated chocks
SKF Vibracon
E-CSTR series
Chocks are often installed in demanding environments, including humid and salty climates – where enhanced corrosion protection is recommended. (It is worth noting that SKF Vibracon chocks were originally developed for marine applications.)
To satisfy this need, SKF has tested a range of protective solutions, resulting in its surface-treated chocks. Each part is individually surface treated, which helps to give the chocks a consistent quality and extended performance against corrosion.

Stainless steel chocks
SKF Vibracon
E-SS series
For the most demanding environments where carbon steel surface-treated chocks will not suffice, SKF has developed a range of stainless-steel chocks. Mating surfaces are treated with additives to prevent parts from seizing when adjusted.
Coupled with recent performance improvements, such as increased load capacity, they are suitable but not limited to be used in industries such as oil & gas or offshore.

Low profile chocks
SKF Vibracon
ELP-ASTR series
These chocks are aimed at applications with limited available chocking heights. Low profile chocks offer an economic alternative to the expensive milled chocks, shims or epoxy resins typically used for re-chocking projects or previously designed solutions.
Each part is individually surface treated, which helps to give the chocks a consistent quality and extended performance against corrosion. They can be fitted easily and cost-effectively, which helps machine owners who are on a tight installation schedule.

Spherical washers
Straight bolt tensioning for longer endurance
Spherical washers from SKF are designed to create an exact, parallel plane between the bolt head and the face of the nut. These washers automatically adjust and compensate for the angular deviation between the planes and prevent the bolt from bending.
- Automatically compensates for angular errors
- Evenly distributed bolt tension
- Reduces bolt fatigue from bending bolts
- Improved bolt stretch possible due to increased clamping length
- Surface treated for protection in humid and harsh environments
- Available in standard and low-profile (LP) versions
