Overview

ASTM F2590-06(2022) is the internationally recognized standard specification for bearing, roller, thrust, two channeled race surface, rigid or flat seat type. Issued by ASTM International, this standard specifies the requirements for thrust roller bearings designed for slow rotating or oscillating applications subjected to pure thrust loads. The standard covers material composition, physical properties, design features, dimensions, surface finish, marking, and packaging requirements. Widely referenced in both commercial and defense procurement, this specification helps ensure performance and quality of thrust roller bearings used in critical applications.

Key Topics

• Material Requirements: Specifies high carbon chromium alloy steel for bearing construction, ensuring durability and performance under thrust loading.
• Physical Properties:
  • Heat treatment: Bearing races and rollers must be through-hardened to stringent Rockwell hardness requirements.
  • Surface finish: Details precise surface roughness values for all functional surfaces, in accordance with ASME B46.1 standards.
• Design Features:
  • Rigid or flat seat type with two channeled race surfaces.
  • Available in retainer and retainerless types to suit different applications.
• Load Ratings: Differentiates between steering pivot rating (for oscillating loads, originally for steering axles in trucks) and intermittent operation rating (for rotational applications up to 50 rpm).
• Dimensions and Variations: Tables for essential dimensions, tolerances, and permissible variations ensure compatibility and interchangeability between components.
• Marking and Identification: Requires stringent marking practices, including military part numbers and manufacturer identification, to streamline procurement and traceability.
• Packaging and Preservation: Outlines packaging and preservation requirements to protect product integrity during storage and transport.

Applications

ASTM F2590-06(2022) bearings are engineered for specialized thrust-load applications requiring reliability and longevity:

• Steering Gear Service: Predominantly used in the king pins of front axles on heavy trucks, where the bearing is subjected to frequent oscillation and shock loads.
• Crane Hooks and Lifting Equipment: Suitable for applications with steady pull loads, such as rotary crane hooks, provided speed limitations are observed.
• Low-Speed Oscillating Machinery: Ideal for industrial machinery operating under slow rotation or oscillation (speed not exceeding 50 rpm for retainerless types or 5 rpm for steering pivot uses).
• Defense and Military Equipment: Meets requirements originally established by the U.S. Department of Defense (per MS17169), ensuring compatibility in military settings.

Related Standards

Implementing ASTM F2590-06(2022) typically occurs alongside several linked standards, supporting comprehensive quality assurance and industry alignment:

• ABMA Std. 1: Terminology for Antifriction Ball and Roller Bearings and Parts
• ASME B46.1: Surface Texture (Surface Roughness, Waviness, and Lay)
• ISO 5593: Rolling Bearings – Vocabulary
• MS17169: Legacy military specification for similar thrust roller bearings
• MIL-STD-102, MIL-STD-129, MIL-STD-130: Various standards for component parts, shipment, storage, and marking in military contexts
• SAE AMS-STD-66: Steel chemical composition and hardenability

Practical Value

Using bearings manufactured according to ASTM F2590-06(2022) provides:

• Consistency and Interchangeability: Adherence to uniform material, dimensional, and marking standards ensures compatible parts across suppliers and installations.
• Reliability: Strict material and heat treatment requirements guarantee performance in demanding thrust-load environments.
• Compliance: Widely accepted by governmental and defense procurement organizations, supporting easier sourcing and auditability.

Organizations and engineers seeking proven, dependable thrust roller bearings for slow rotation or oscillating applications will benefit from specifying ASTM F2590-06(2022) in their technical and procurement documentation, ensuring safety, compatibility, and long-term operational integrity.

pivot rating includes a safety factor of approximately 2.0 to
compensate for the indeterminate shock and vibration.
Therefore, when these bearings are used in crane hook appli-
cations or other similar steady pull applications, the steering
pivot rating can be doubled. It should also be kept in mind that
these bearings were designed for oscillating or slow rotation
applications only and should never be operated at speeds
higher than 5 rpm.
