20kg Olympic Weightlifting Barbell 170k PSI 42CrMo Alloy Steel Bar PROESCE OB86‑CFG

Product Features And Advantages：

The OB86‑CFG high-performance weightlifting barbell is forged from premium 42CrMo alloy steel, into a 20kg barbell with an overall length of 220cm and a standard shaft diameter of 28mm. It delivers a tensile strength of 170k PSI and supports a maximum safe load of 1000lb. The bar shaft adopts a camouflage Teflon coating with professional knurled grip texture for enhanced slip resistance and corrosion resistance. The bar sleeves undergo QPQ composite surface treatment to achieve excellent wear and rust resistance. Built with an internal structure of 8 needle bearings and 2 bushings, the sleeves rotate ultra-smoothly, reducing inertial resistance and wrist torsion during explosive lifting movements such as snatches and clean & jerks. Ideal for professional fitness centers, powerlifting gyms and Functional facilities, it fully meets professional barbell and weights strength training needs including squats, bench presses, dead-lifts and Olympic lifts. Custom logo printing and surface finish OEM services are available to support gym bulk procurement and cross-border B2B wholesale business.

Product Characteristics：

1.42CrMo Alloy Steel Shaft
Forged from high-quality 42CrMo alloy steel with exceptional toughness and superior bend recovery performance. It resists permanent deformation under heavy loads, serving as the premium standard material for professional weightlifting barbells.

2.170k PSI High Tensile Strength
Boasts a high tensile strength of 170k PSI with a maximum safe load of 1000lb, capable of withstanding high-frequency and heavy-duty training in any barbell gym for professional powerlifting and Olympic weightlifting.

3.Camouflage Teflon Shaft with Professional Knurled Grip
The Teflon-coated shaft features a stylish camouflage appearance and precision knurled texture, greatly increasing friction for a firm non-slip grip even with sweaty hands. The premium coating provides outstanding corrosion and rust resistance with a smooth, skin-friendly touch.

4.QPQ-Treated Barbell Sleeves
The sleeves adopt advanced QPQ salt-bath composite surface treatment technology to enhance surface hardness, delivering excellent wear resistance and anti-rust performance. They resist scratches from frequent plate loading and unloading, effectively extending service life.

5.8 Needle Bearings + 2 Bushings Transmission Structure
The combined structure of 8 needle bearings and 2 bushings enables ultra-smooth sleeve rotation. During explosive weightlifting movements, the sleeves rotate freely with weight plates to reduce wrist torsion pressure, perfectly adapting to Olympic explosive training scenarios.

6.Standard Olympic Specification Size
Features standard Olympic dimensions of 220cm overall length and 28mm shaft diameter, fully compatible with all conventional Olympic large-hole weight plates for universal application.

Usage Instructions & Precautions

1.Inspect the gym barbell before use to ensure smooth sleeve rotation and tight end caps on both sides.

2.Never exceed the maximum load capacity of 1000lb; overloaded training is strictly prohibited.

3.Firmly lock the weight plates on both ends of the barbell to prevent plate slipping during training.

4.Avoid rough dropping or violent throwing of the barbell from height, which may cause shaft bending and internal bearing damage.

5.Do not store the barbell in humid environments for a long time. Wipe the shaft and sleeves regularly to keep dry and extend service life.

6.Stop use immediately if shaft bending, sleeve shaking & abnormal noise or loose end caps are found.

Frequently Asked Questions：

I.Selection

Q: Who is this 28mm Olympic bar suitable for?
A: This standard 20kg 28mm olympic barbell is ideal for advanced trainers and professional gyms, perfect for squats, bench presses, dead-lifts and all Olympic weightlifting movements.

II.Material

Q: What is the difference between 42CrMo alloy steel and ordinary carbon steel barbells?
A: 42CrMo alloy steel features better toughness and bend recovery, resisting permanent deformation under heavy loads. Ordinary carbon steel bars are more prone to irreversible bending under high weight pressure.

III. Specification

Q: What is the difference between bearing and bushing versions?
A: This 8 needle bearing + 2 bushing structure provides ultra-smooth sleeve rotation for an olympic weightlifting barbell, ideal for explosive movements like snatches and clean & jerks. Pure bushing bars have higher rotational resistance and are more suitable for basic strength training.

IV. Usage

Q: Can the barbell be dropped directly on the ground?
A: Rough dropping is not recommended. Repeated violent impact will damage internal bearings, causing abnormal noise and rotational jamming over time.

V.Customization

Q: Can custom logos and customized shaft coatings be made?
A: Custom logo engraving and surface coating customization are available for orders meeting the minimum quantity requirement.

VI.Sample

Q: Are sample orders available?
A: Samples are supported, with sample fees, logistics costs and wooden frame packaging fees borne by the buyer.

VII. Packaging

Q: What is the factory default packaging?
A: Reinforced paper tube packaging with wooden case to prevent transportation damage, supporting full container bulk shipment.

VIII. Maintenance & Care

Q: How to maintain the barbell?
A: Keep the barbell dry and clean, wipe off moisture in humid environments to prevent rust. Avoid contact with corrosive liquids. Regularly check and fasten the sleeve end cap screws.
