Product Description
The 256907 (GOST designation, also referenced as 6-256907E) is a Russian GOST-standard double-row angular contact ball bearing engineered specifically as the front wheel hub bearing for key Russian and Soviet-era vehicle platforms — including the LADA VAZ-2108/2109 Samara, LADA 2121 Niva 4×4, and Moskvich-21412, as well as KAMAZ heavy trucks and ZIL commercial vehicles. With dimensions of 34mm bore × 64mm OD × 37mm width, a weight of 0.445 kg, a dynamic load rating of Cr=31.5 kN, and a static load rating of Cor=27.9 kN, the 256907 is a precision-engineered bearing optimised for the combined radial and axial load conditions of front wheel hub applications on Russian vehicle platforms.
The 256907 GOST designation follows the Russian bearing numbering system where "25" denotes the double-row angular contact ball bearing configuration, "69" encodes the dimensional series (34mm bore, 64mm OD), and "07" identifies the design variant. The suffix "E" in the alternate designation 6-256907E indicates an enhanced internal geometry variant optimised for improved load distribution in wheel hub applications.
NEXANS Bearing manufactures the 256907 to ISO standard with full GOST certification — ensuring seamless compatibility with Russian vehicle factory specifications while meeting international quality standards. The GCr15 chrome steel construction, pre-lubricated double-sealed design, and angular contact double-row ball bearing geometry provide the durability, precision, and combined load capacity required for the demanding front wheel hub environment of Russian vehicle platforms.

Load Rating Note: The Cr=31.5 kN dynamic and Cor=27.9 kN static load ratings confirmed by Alibaba reflect the 256907's optimisation for the moderate combined loads of passenger car and light truck front wheel hub applications — providing an excellent balance of load capacity, compact dimensions (34×64×37mm), and lightweight construction (0.445 kg) for the Russian vehicle platforms it serves.
Non-Standard Bore Note: The 256907's 34mm bore is a non-standard dimension in the international ISO series — a characteristic of Russian GOST bearing design where bore sizes were optimised for Soviet-era vehicle axle shaft diameters rather than the standard ISO 5mm-increment bore series. This makes the GOST 256907 designation essential for correct procurement.

GOST 256xxx Series Logic: The 256907 (34mm bore, 64mm OD) occupies a unique position in the LADA wheel bearing family — serving the transitional platform between the older VAZ-2108 Samara and the newer Kalina/Granta generation. Its non-standard 34mm bore is specifically engineered for the VAZ-2108/Niva axle shaft diameter, making the GOST 256907 designation the only correct procurement reference for this application.
✅ GOST 256907 Certified — Native Russian GOST designation with full certification documentation — the correct part number for Russian and CIS aftermarket procurement and customs compliance

Q1: What vehicle does the 256907 bearing fit?
The 256907 is the front wheel hub bearing for LADA VAZ-2108, 2109, 21099 (Samara), LADA 2121 Niva 4×4, and Moskvich-21412, as well as KAMAZ and ZIL vehicles.
Q2: What are the dimensions and load ratings of the 256907?
The 256907 measures 34mm bore × 64mm OD × 37mm width, weighing ≤0.445 kg. Dynamic load rating Cr=31.5 kN, static load rating Cor=27.9 kN — confirmed by Alibaba product data.
Q3: What is the difference between 256907 and 256707?
Both are GOST-standard LADA front wheel hub bearings with 37mm width, but the 256907 (34×64×37mm) fits the VAZ-2108/2109 Samara, Niva 2121, and Moskvich-21412, while the 256707 (35×68×37mm) fits the newer Kalina/Granta/Priora platforms. The 256907's non-standard 34mm bore is specific to the older VAZ-2108/Niva axle shaft design.
Q4: What is the alternate designation for the 256907?
The alternate GOST designation is 6-256907E — where the "E" suffix indicates an enhanced internal geometry variant. The international DAC equivalent is DAC34640037 (encoding 34mm bore, 64mm OD, 37mm width).
Q5: Why does the 256907 have a non-standard 34mm bore?
The 34mm bore is a Russian GOST-specific dimension engineered for the VAZ-2108/Niva axle shaft diameter — a Soviet-era design choice that does not align with the standard ISO 5mm-increment bore series. This makes the GOST 256907 designation the only correct procurement reference — no standard ISO bearing substitutes this part.
Q6: What is the material of the 256907 bearing?
The 256907 is manufactured from GCr15 chrome steel — confirmed by both NEXANS official data and Made-in-China supplier data — providing maximum hardness, wear resistance, and fatigue life for front wheel hub applications.
Q7: Is the 256907 GOST certified?
✅ Yes. NEXANS Bearing holds full GOST certification for its Russian auto wheel bearing series — ensuring compliance with Russian technical regulations and customs requirements.
Q8: Does NEXANS supply the complete DAC34 bearing series?
✅ Yes. NEXANS supplies the complete DAC34 series — from DAC34620037 through DAC34670037 and beyond — covering all major Russian and international vehicle platforms requiring 34mm bore wheel hub bearings, all from 3,000m² warehouse with fast delivery.
