SKF Vibracon Surface Treated Chocks (E-CSTR Series)

Surface Treated Chocks

Chocks are often installed in demanding environments, including humid and salty climates – where enhanced corrosion protection is recommended. 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.

Key Features:

• Enhanced corrosion protection compared to bare carbon steel

• Individual surface treatment for consistent quality

• Extended performance in corrosive environments

• Maintains all benefits of standard carbon steel chocks

• Cost-effective solution for corrosion protection

• Originally developed for marine applications

When to Use Surface Treated Chocks:

Surface treated chocks are ideal for humid and salty climates, marine and offshore applications, industrial environments with moisture exposure, chemical processing plants, food processing facilities where washdown is common, and any application requiring enhanced corrosion resistance without the cost of stainless steel.

Key Benefits of Surface Treatment:

• Prevents rust formation and material degradation

• Reduces maintenance requirements

• Extends equipment lifespan

• Provides reliable performance in harsh environments

• Cost-effective alternative to stainless steel in many applications

Typical Applications:

• Coastal industrial facilities

• Marine and offshore equipment

• Food and beverage processing

• Chemical and petrochemical plants

• Humid factory environments

• Equipment subject to washdown

• Any moisture-exposed installation

Available Sizes:

The E-CSTR series is available in 10 sizes, from SM 12 (for M12-M16 bolts) through SM 64 (for M64-M68 bolts), providing flexibility for virtually any mounting requirement.

For extreme corrosive environments requiring maximum corrosion resistance, consider our Stainless Steel (E-SS) option. For cost-conscious indoor applications, choose our Carbon Steel (E-CS) chocks.
