The K1YC9 combination is one of the most specification-dense GOST suffix strings in the LADA bearing range — four distinct elements, each carrying a critical meaning:
Code Element | GOST Meaning | Significance |
6 | GOST rolling bearing series prefix | Standard GOST prefix |
1805 | GOST wide series deep groove ball bearing | Wider than standard 6xxx series — non-interchangeable with standard metric bearings |
02 | Size designation (15×35mm bore/OD) | Defines dimensional envelope within the 1805 series |
K1 | First-variant internal design modifier | Specific internal geometry modification (variant 1) required by AvtoVAZ OEM specification |
Y | Rubber seal on both sides | Equivalent to 2RS in ISO nomenclature — contact seals on both inner and outer races |
C9 | Special GOST clearance grade | Non-standard clearance grade unique to GOST — defines specific internal radial clearance required for the VAZ-2101 front hub application |
Key Takeaway: The C9 clearance grade is particularly critical — it is a GOST-specific clearance designation that does not correspond directly to the standard ISO C0/C2/C3 grades. The correct C9 clearance is essential for proper front wheel hub preload and bearing longevity. Always specify the full part number 6-180502K1YC9 or OEM number 2101-1701031.
This is the most important sourcing distinction for this bearing:
Parameter | 6-180502K1YC9 (GOST 1805) | 6202-2RS (ISO Standard) |
Inner Diameter | 15 mm | 15 mm |
Outer Diameter | 35 mm | 35 mm |
Width | 14 mm⚠️ | 11 mm⚠️ |
Series | GOST 1805 (Wide series) | ISO 62xx (Standard series) |
Clearance | C9 (GOST special) | C0 (standard) |
Internal Design | K1 modifier | Standard |
OEM Application | LADA VAZ-2101 front hub | General industrial / automotive |
Interchangeable? | ❌ No | ❌ No |
⚠️ CRITICAL WARNING: The 6-180502K1YC9 and the standard 6202-2RS share the same bore (15mm) and outer diameter (35mm) but have different widths (14mm vs 11mm). Installing a standard 6202-2RS in place of the 6-180502K1YC9 will result in incorrect axial positioning, improper preload, and potential front wheel hub failure. Always source the correct GOST 1805 series bearing using OEM number 2101-1701031.

⚠️ The GOST 1805 series (15×35×14mm) has no direct ISO/international standard equivalent. The 14mm width is unique to the GOST wide series. Always source by OEM number 2101-1701031 or GOST number 6-180502K1YC9. Do not substitute with standard 6202-2RS (15×35×11mm).
The 6-180502K1YC9 (2101-1701031) is the front wheel hub inner bearing for the LADA VAZ-2101 Klassika series:
Platform | Application | Position |
LADA VAZ-2101 (Zhiguli / Klassika) | Front wheel hub assembly | Inner bearing position |
LADA VAZ-2102 / 2103 / 2104 / 2105 / 2106 / 2107 | Front wheel hub assembly | Inner bearing position — confirm with OEM number |
Other LADA Klassika Variants | Contact us to confirm | — |
The LADA Klassika front wheel hub uses two bearings in the same hub assembly — an inner and an outer bearing. The 6-180502K1YC9 (2101-1701031) is the inner bearing. Always replace both inner and outer front hub bearings simultaneously. Contact our technical team to confirm the matching outer bearing part number for your application.
The LADA Klassika front wheel hub uses a paired bearing arrangement:
Position | GOST Number | OEM Number | Key Spec |
Inner Bearing | 6-180502K1YC9 | 2101-1701031 | 15×35×14mm, K1YC9 |
Outer Bearing | Contact us to confirm | Contact us to confirm | Confirm with technical team |
Always replace both inner and outer front hub bearings as a matched pair. Replacing only one bearing will result in mismatched wear rates and premature failure of the new bearing. Contact Nexans Bearings to source the complete front hub bearing set for your LADA application.
Reason | Explanation |
Wider load distribution | The 14mm width (vs 11mm standard) provides a larger raceway contact area, distributing front hub loads more effectively |
Axial load capacity | Greater width improves the bearing's ability to handle the axial thrust loads generated by cornering on the VAZ-2101 front suspension geometry |
AvtoVAZ engineering standard | The GOST 1805 wide series was specified by AvtoVAZ engineers for the VAZ-2101 front hub to meet durability requirements under Soviet/Russian road and load conditions |
C9 clearance precision | The special C9 clearance grade provides the exact internal clearance required for correct front hub preload — critical for steering precision and bearing longevity |
K1 internal design | The first-variant internal design modification optimises the bearing geometry for the specific load profile of the VAZ-2101 front hub inner position |
The 6-180502K1YC9 is a GOST 1805-series wide deep groove ball bearing manufactured to OE-equivalent specifications for the LADA VAZ-2101 front wheel hub inner position. At 15×35×14mm, it is 3mm wider than the superficially similar standard 6202-2RS (15×35×11mm) — a critical dimensional difference that makes it unique to the GOST wide series and non-interchangeable with standard metric bearings.
The K1YC9 suffix — the most specification-dense GOST code in the LADA bearing range — combines a first-variant internal design modification (K1), double rubber sealing (Y), and a special GOST clearance grade (C9) to meet the precise engineering requirements of the AvtoVAZ OEM application 2101-1701031.
This bearing delivers:
Correct front hub geometry — 14mm wide series width provides proper axial positioning within the VAZ-2101 front hub assembly
Precise C9 clearance — special GOST clearance grade ensures correct front hub preload for steering precision and bearing longevity
K1 optimised internal design — first-variant internal geometry modification for the VAZ-2101 inner hub position load profile
Superior contamination resistance — Y rubber seals block dust, road grit, and moisture in front wheel hub environment
OE-equivalent fit — manufactured to full GOST K1YC9 specification for direct OEM replacement of 2101-1701031
Chrome steel durability — GCr15 / 52100 material provides high hardness, wear resistance, and fatigue strength
Sourced from Nexans Bearings' trusted manufacturing network — including leading Chinese bearing brands QC, C&U, ZWZ, TWB, and ZWA — every unit undergoes strict dimensional and quality inspection before dispatch.

This bearing is referenced as 6-180502K1YC9 (GOST), 2101-1701031 (AvtoVAZ OEM), and 38-1476 (NKS reference). The GPZ designation is 180502K1YC9.
The dimensions are: Inner Diameter 15mm × Outer Diameter 35mm × Width 14mm. The 14mm width is critical — it is unique to the GOST 1805 wide series and is 3mm wider than the standard 6202-2RS (15×35×11mm).
K1 = first-variant GOST internal design modifier; Y = rubber seals on both sides (equivalent to 2RS); C9 = special GOST clearance grade with a specific internal radial clearance unique to this OEM application. All four elements are mandatory — always order the full 6-180502K1YC9.
C9 is a special GOST clearance grade that defines a specific internal radial clearance for the VAZ-2101 front hub application. It does not correspond directly to the standard ISO C0/C2/C3 grades. The correct C9 clearance is essential for proper front hub preload, steering precision, and bearing longevity. Using a bearing with incorrect clearance will cause premature failure or unsafe wheel play.
No. While both bearings share the same bore (15mm) and outer diameter (35mm), the 6-180502K1YC9 is 14mm wide versus the 6202-2RS at 11mm wide. This 3mm difference means the standard bearing will not fit correctly in the VAZ-2101 front hub assembly, causing incorrect axial positioning and potential hub failure. Always use OEM number 2101-1701031.
The 6-180502K1YC9 (2101-1701031) is the inner bearing of the LADA VAZ-2101 front wheel hub assembly. The front hub uses two bearings (inner + outer). Contact us to confirm the matching outer bearing part number for your application.
Yes — always replace both front hub bearings as a matched pair. Replacing only one bearing results in mismatched wear rates and premature failure of the new bearing. Contact Nexans Bearings to source the complete front hub bearing set.
This bearing is used in the LADA VAZ-2101 (Zhiguli / Klassika) front wheel hub inner position, and likely in related Klassika models (2102–2107). Confirm fitment for other models using OEM number 2101-1701031 or contact our technical team.
