Common 52100 Bearing Steel Specifications & Heat Treatment
| Grade | 52100 Bearing Steel |
|---|---|
| Common bar standards | ASTM A295 for high-carbon bearing-quality 52100 steel. |
| Heat-treatment condition | Typically spheroidize annealed for forming/machining, or hardened and tempered for bearing use. |
| Rod dimensions | Finished OD and upper/lower limits; length, quantity, straightness, surface roughness and certs as required. |
Bearing-grade cleanliness and final heat treatment must be defined with bearing application specifications.
These are common references, not automatic certification/availability or an in-house heat-treatment claim. The order’s material specification, condition, outside processing if any, and acceptance requirements govern.
ALLOY, NICKEL & SPECIALTY STEELS / PRECISION ROD STOCK
High-carbon chromium bearing steel frequently used for hardened wear-related parts.
52100 Bearing Steel Grade and Purchasing Standard
SAE/AISI 52100, UNS G52986 when specified; confirm ASTM A295 or relevant bearing quality standard. Request a mill test report and condition certification whenever the material grade or final mechanical properties are critical. A ground rod’s dimensions and appearance do not establish metallurgical conformance.
Material Condition and Ground Finish
Annealed supply versus final hardened condition must be defined with hardness and cleanliness criteria.
The manufacturing sequence may involve heat treatment, straightening and outside-diameter finishing. These steps should be planned around the material’s condition and the application’s surface/straightness requirements, especially for long slender parts.
Where 52100 Bearing Steel Ground Rods May Be Used
Bearing components, precision rollers and hardened wear parts.
The component’s design and acceptance standard must be used to establish whether the alloy is appropriate. These are application examples, not a representation that the supplier is approved for any specific regulated industry.
52100 Bearing Steel Centerless Ground & TG&P Bar Options
52100 Bearing Steel Centerless Ground Bar
For 52100 Bearing Steel centerless ground rod or bar, bearing applications can require cleanliness, decarburization and hardness controls beyond the ground outside diameter. Review precision centerless grinding when specifying your finished outside diameter.
52100 Bearing Steel TG&P / Turned, Ground & Polished
When a drawing calls for 52100 Bearing Steel TG&P (TGP) or turned, ground and polished rod, 52100 TG&P is not equivalent to bearing-grade approval; verify cleanliness requirements, finished condition and acceptance criteria. Explore bar supply and surface finishing.
Centerless-ground bar and TG&P shafting are not synonymous. Verify material condition, full route, OD tolerance, straightness, surface finish and available lengths against the RFQ. Request pricing →
Engineering Considerations
Bearing-quality requirements, inclusion limits and heat treatment are not automatically guaranteed by a ground finish.
Required Details for a Complete Rod Quote
- Alloy: full designation, standard and condition, plus any material test report or special examination requirements.
- Geometry: finished outside diameter, upper/lower limits, length, straightness with inspection span and surface roughness where specified.
- Processing: identify supply of finished rod stock versus grinding customer-owned material, heat-treatment sequence and protective handling.
- Production: quantity, release schedule, required delivery date and ship-to area.
Ask About Availability and Precision Processing
Precision Ground Rods coordinates sourcing and finishing inquiries on a quotation basis. We assess material availability and manufacturing suitability per order, including outside-diameter grinding, straightening, polishing and cut-to-length operations as appropriate.
