Material & Precision Process
High-Carbon Chromium Steel (GCr15)
Inner/outer rings and balls made from GCr15 bearing steel -- superior hardness, fatigue resistance, and dimensional stability under cyclic loading.
Precision Grinding & Raceway Finishing
Raceways undergo multi-stage grinding and superfinishing to Ra ≤ 0.1 µm for minimal friction, reduced heat generation, and extended service life.
Cage Options: Steel / Polyamide / Brass
Pressed steel cage (standard), high-strength polyamide cage (TVH) for high-speed use, and brass cage (MA) for extreme-temperature environments.
Seal & Shield Options
Available open, with metal shields (Z) for moderate contamination protection, or contact rubber seals (RS/RSR) for grease retention and dust exclusion.

Engineering-Grade Performance

Every FAG 6308 bearing is manufactured to deliver consistent performance across the full service life -- not just at initial installation.

High-Speed Stability

Optimized ball-to-raceway geometry and precision-balanced cage deliver smooth, vibration-free rotation up to 9,500 rpm reference speed -- ideal for high-cycle motor applications.

Proven Load Capacity

Dynamic load rating of 38.0 kN and static rating of 24.0 kN handle demanding radial and moderate axial loads, covering a wide range of industrial equipment without oversizing.

Extended Service Life

GCr15 steel with controlled heat treatment ensures fatigue resistance rated at L10 life exceeding 1,000 hours in standard motor conditions -- reducing unplanned downtime.

Low Noise & Low Vibration

Superfinished raceways (Ra ≤ 0.1 µm) and precision-matched ball sets achieve V3/V4 vibration class -- meeting the acoustic demands of home appliances and precision instruments.

Multi-Configuration Flexibility

Open, shielded (2Z), and sealed (2RS/2RSR) variants plus C3 clearance and P5/P6 precision grades allow direct substitution across diverse OEM and aftermarket applications.

Genuine FAG Quality

Every unit supplied is authentic FAG product with full traceability documentation, batch certification, and ISO 9001 / TS 16949 quality records available on request.

Trusted by Global Procurement Teams

Procurement managers and plant engineers from across the world share their experience sourcing FAG 6308 bearings through SKF China.

"We switched our motor assembly line to FAG 6308-2RS sourced through SKF China. The dimensional consistency across the entire batch was exceptional -- zero rejects in incoming QC. Delivery to Germany in under 3 weeks."

Common Questions

Answers to the questions we hear most from procurement teams and engineers.

What is the difference between FAG 6308, 6308-2Z, and 6308-2RS? +
The base 6308 is an open bearing with no sealing -- suitable when external lubrication is applied regularly. The 6308-2Z has pressed steel shields on both sides, offering protection against coarse particles while allowing some grease to escape (non-contact shield). The 6308-2RS (or 6308-2RSR in FAG designation) uses rubber contact seals on both sides, providing superior grease retention and dust exclusion -- ideal for maintenance-free applications. For most motor and fan applications, 6308-2RS is the most common choice. Ask a specialist
What does the C3 clearance designation mean for 6308-C3? +
C3 indicates a larger-than-normal internal radial clearance between balls and raceways. Standard (CN) clearance is used for most general applications. C3 clearance is specified when the bearing will operate at elevated temperatures (causing thermal expansion of the shaft/housing), or when interference fits are used on both rings simultaneously. For electric motors running at higher ambient temperatures or with tight shaft fits, C3 is often the correct specification. Ask a specialist
Can you supply FAG 6308 with full certification documentation? +
Yes. We can provide batch inspection reports, material certificates (GCr15 steel), dimensional inspection records, and ISO 9001 / TS 16949 quality certificates for every shipment. Documentation packages are available in English and can be prepared to meet specific import compliance requirements for European and North American markets. Please specify your documentation requirements when placing an inquiry. Request documentation list
What is the typical lead time and minimum order quantity? +
For standard variants (6308, 6308-2Z, 6308-2RS, 6308-C3) held in stock, dispatch is within 24-48 hours of order confirmation. Delivery to Europe typically takes 12-18 days by sea freight or 5-7 days by air. Minimum order quantities are flexible -- we accommodate both small trial orders and large volume procurement. For orders exceeding $50,000, complimentary sample sets are available before full commitment. Contact us with your quantity and destination for a precise lead time. Get lead time estimate
Is FAG 6308 compatible with NSK, SKF, or NTN equivalents? +
Yes. The 6308 is a standardized bearing designation per ISO 15 / DIN 625. The bore (40 mm), outer diameter (90 mm), and width (23 mm) are identical across FAG, SKF, NSK, NTN, KOYO, and other ISO-compliant manufacturers. Direct interchangeability applies to the base dimensions. However, internal design details -- cage material, raceway geometry, grease specification, and clearance -- may differ between brands and can affect performance in demanding applications. We can advise on the best match for your specific operating conditions. Confirm cross-reference
Do you offer volume pricing for large OEM orders? +
Yes. We offer tiered pricing for volume orders, with dedicated account management and priority stock allocation for OEM clients with recurring requirements. Long-term supply agreements with fixed pricing and delivery schedules are available for qualified buyers. Contact our team via WhatsApp with your annual volume estimate to receive a tailored commercial proposal. Discuss volume pricing
