Angle rings (L-shaped thrust collars)

SKF Angle Rings Roller, also known as L-Shaped Thrust Collars, are precision-engineered components designed to provide axial positioning and load support in rotating machinery. These collars feature a unique L-shaped cross-section that integrates seamlessly with cylindrical roller bearings or other bearing types, enabling precise alignment, thrust load management, and enhanced system stability. Ideal for applications requiring rigid axial guidance, SKF’s L-shaped collars are manufactured to exacting standards, ensuring reliability in high-load,

Key Features & Technical Advantages of SKF Angle Rings Roller (L-Shaped Thrust Collars)

  1. Axial Load Management & Positioning

Primary Function:

L-shaped thrust collars act as axial load shoulders, transferring thrust forces between rotating and stationary components (e.g., shafts, housings). Their geometry ensures stable positioning of bearings, preventing axial displacement under operational stress.

High Axial Stiffness:

The rigid L-profile resorts to rigid axial guidance, minimizing deflection even under heavy or uneven loads.

  1. Optimized Design for Integration

L-Shaped Cross-Section:

The 90° angle design allows the collar to interface directly with bearing rings or housing surfaces, simplifying assembly and reducing the need for additional spacers or shims.

Precision Ground Surfaces:

Critical contact surfaces (radial and axial faces) are ground to tight tolerances (ISO P6/P5 class), ensuring smooth load transfer and alignment accuracy.

  1. Material & Durability

High-Grade Steel Construction:

Manufactured from case-hardened or through-hardened steel (e.g., SAE 52100), SKF L-shaped collars offer exceptional wear resistance and fatigue strength.

Surface Treatments:

Optional coatings (e.g., phosphate, zinc, or Durotect®) enhance corrosion resistance in harsh environments (marine, chemical, or high-humidity applications).

  1. Versatility & Customization

Interchangeable Sizing:

Available in standardized dimensions to match common bearing series (e.g., SKF cylindrical roller bearings), ensuring compatibility across industrial platforms.

Customizable Configurations:

SKF offers tailored solutions for non-standard applications, including:

Bore and OD Variations: Adjustments to fit unique shaft or housing dimensions.

Grooves and Lubrication Channels: Integrated oil/grease passages for automated lubrication systems.

Flange Modifications: Additional bolt holes or alignment features for complex assemblies.

  1. Simplified Installation & Maintenance

Split Design Options:

Select collars feature split construction, enabling installation without disassembling shafts or adjacent components—critical for retrofitting or maintenance in confined spaces.

Reduced Downtime:

Precision-machined collars minimize alignment adjustments during installation, accelerating commissioning or repair processes.h-speed, or misalignment-prone environments.

Applications & Industry Use Cases

SKF L-shaped thrust collars are indispensable in industries where precise axial control and load management are critical:

  1. Heavy Machinery & Industrial Equipment

Gearboxes & Turbines: Axial positioning of gears and rotors in wind turbines, steam turbines, or industrial gearboxes.

Mining & Construction: Support axial loads in crushers, conveyors, and excavator slew rings.

  1. Automotive & Transportation

Wheel Hubs: Axial retention of bearings in heavy-duty trucks, trailers, or rail systems.

Transmission Systems: Thrust load management in differentials or powertrain assemblies.

  1. Energy & Power Generation

Hydraulic Pumps/Generators: Maintain rotor alignment in hydroelectric turbines or pump shafts.

Nuclear & Thermal Plants: High-reliability axial guidance in coolant pumps or reactor systems.

  1. Marine & Offshore

Propulsion Shafts: Withstand thrust forces in ship propeller shafts while resisting saltwater corrosion.

Offshore Drilling Rigs: Axial load support in drawworks or top drives.

  1. Material Processing

Steel Mills: Position bearings in rolling mill stands under extreme thermal and mechanical stress.

Paper & Pulp Machinery: Axial control in dryer sections or calender rolls

SKF Angle Rings Roller (L-Shaped Thrust Collars) are engineered to deliver unmatched precision, durability, and adaptability in axial load applications. Whether in heavy industrial machinery, marine propulsion, or energy systems, these collars provide a robust interface for maintaining alignment and managing thrust forces. By integrating SKF’s L-shaped collars, industries achieve higher operational reliability, reduced maintenance costs, and optimized performance—even in the most demanding environments.
