Brand | Nexans Bearings |
Quality Standard | OE-Equivalent / GOST |
Origin | Liaocheng, Shandong, China |
Code Element | GOST Meaning | Significance |
6 | GOST rolling bearing series prefix | Standard GOST prefix |
507 | GOST wide series deep groove ball bearing | Wider OD than standard 6xxx series — OD is 75mm, not 72mm |
06 | Size designation (30mm bore) | Defines dimensional envelope within the 507 series |
Y | Rubber seal on both sides | Equivalent to 2RS in ISO nomenclature — contact seals on both inner and outer races |
The Y suffix is the only suffix on this bearing — indicating double rubber sealing with no additional internal design modification. However, the GOST 507 series designation itself (30×75×19mm) is the critical specification — the 75mm outer diameter is 3mm larger than the standard 6306-2RS (72mm) and makes this bearing unique to the GOST wide series.
The most important sourcing distinction for this bearing:
Parameter | 6-50706Y (GOST 507) | 6306-2RS (ISO Standard) |
Inner Diameter | 30 mm | 30 mm |
Outer Diameter | 75 mm⚠️ | 72 mm⚠️ |
Width | 19 mm | 19 mm |
Series | GOST 507 (Wide series) | ISO 63xx (Standard series) |
Sealing | Y (rubber, both sides) | 2RS (rubber, both sides) |
OEM Application | LADA VAZ-2101 front hub outer | General industrial / automotive |
Interchangeable? | ❌ No | ❌ No |
⚠️ CRITICAL WARNING: The 6-50706Y and the standard 6306-2RS share the same bore (30mm) and width (19mm) but have different outer diameters (75mm vs 72mm). The 3mm OD difference means the standard 6306-2RS will not seat correctly in the VAZ-2101 front hub housing, causing loose fit, vibration, and potential front wheel hub failure. Always source the correct GOST 507 series bearing using OEM number 2101-1701033.
The LADA VAZ-2101 front wheel hub uses two bearings in the same hub assembly. Both must be sourced and replaced together:
Position | GOST Number | OEM Number | Dimensions | Nexans Ref | Key Spec |
Inner Bearing | 6-180502K1YC9 | 2101-1701031 | 15×35×14mm | 38-1476 | K1YC9 — wide series, C9 clearance |
Outer Bearing | 6-50706Y | 2101-1701033 | 30×75×19mm | 38-1477 | Y — wide series, 75mm OD |
✅ Nexans Bearings supplies both bearings — source the complete VAZ-2101 front hub bearing set in a single order. Contact us to request a combined quote for 2101-1701031 + 2101-1701033.
⚠️ Always replace both inner and outer front hub bearings simultaneously. Replacing only one bearing results in mismatched wear rates and premature failure of the new bearing. The inner bearing (6-180502K1YC9) has a significantly smaller bore (15mm) than the outer bearing (6-50706Y, 30mm) — they are completely different bearings and must both be correctly specified.

⚠️ The GOST 507 series (30×75×19mm) has no direct ISO/international standard equivalent. The 75mm outer diameter is unique to the GOST wide series. Always source by OEM number 2101-1701033 or GOST number 6-50706Y. Do not substitute with standard 6306-2RS (30×72×19mm).
The 6-50706Y (2101-1701033) is the front wheel hub outer bearing for the LADA VAZ-2101 Klassika series:
Platform | Application | Position |
LADA VAZ-2101 (Zhiguli / Klassika) | Front wheel hub assembly | Outer bearing position |
LADA VAZ-2102 / 2103 / 2104 / 2105 / 2106 / 2107 | Front wheel hub assembly | Outer bearing — confirm with OEM number |
Other LADA Klassika Variants | Contact us to confirm | — |
Confirm fitment for all models using OEM number 2101-1701033 or contact our technical team.
Reason | Explanation |
Larger OD for housing fit | The 75mm OD is specifically matched to the VAZ-2101 front hub housing bore — a standard 72mm OD bearing will not fit correctly |
Wider load distribution | The GOST 507 wide series provides a larger raceway contact area for the outer hub position, distributing the higher radial loads at the outer bearing position |
AvtoVAZ engineering standard | The GOST 507 series was specified by AvtoVAZ engineers for the VAZ-2101 front hub outer position to meet load and durability requirements |
Paired design with inner bearing | The outer bearing (6-50706Y, 30×75×19mm) is engineered to work in combination with the inner bearing (6-180502K1YC9, 15×35×14mm) — the two bearings share the hub assembly load between them |
The 6-50706Y is a GOST 507-series wide deep groove ball bearing manufactured to OE-equivalent specifications for the LADA VAZ-2101 front wheel hub outer position. At 30×75×19mm, its 75mm outer diameter is the defining specification — 3mm larger than the superficially similar standard 6306-2RS (30×72×19mm) — making it unique to the GOST wide series and non-interchangeable with standard metric bearings.
As the outer bearing of the VAZ-2101 front hub assembly, the 6-50706Y works in tandem with the inner bearing 6-180502K1YC9 (2101-1701031) to support the full range of radial, axial, and moment loads generated by the front wheel hub during driving, steering, and braking.
This bearing delivers:
Correct front hub housing fit — 75mm OD precisely matches the VAZ-2101 front hub housing bore
Reliable radial and axial load handling — deep groove geometry supports combined loads in the outer hub position
Superior contamination resistance — Y rubber seals block dust, road grit, and moisture in front wheel hub environment
Excellent grease retention — factory pre-lubricated, sealed for life under normal operating conditions
OE-equivalent fit — manufactured to GOST 507 series specification for direct OEM replacement of 2101-1701033
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 6-50706Y (GOST), 2101-1701033 (AvtoVAZ OEM), and 38-1477 (NKS reference). The GPZ designation is 50706Y.
The dimensions are: Inner Diameter 30mm × Outer Diameter 75mm × Width 19mm. The 75mm outer diameter is critical — it is unique to the GOST 507 wide series and is 3mm larger than the standard 6306-2RS (30×72×19mm).
The Y suffix denotes rubber seals on both sides — equivalent to the 2RS designation in ISO/international standards. The seals contact both inner and outer races, providing superior protection against dust and moisture.
No. While both bearings share the same bore (30mm) and width (19mm), the 6-50706Y has a 75mm outer diameter versus the 6306-2RS at 72mm. This 3mm OD difference means the standard bearing will not seat correctly in the VAZ-2101 front hub housing, causing loose fit, vibration, and potential hub failure. Always use OEM number 2101-1701033.
The 6-50706Y (2101-1701033) is the outer bearing of the LADA VAZ-2101 front wheel hub assembly. The inner bearing is the 6-180502K1YC9 (2101-1701031). Both must be replaced simultaneously.
The matching inner bearing is the 6-180502K1YC9 (OEM: 2101-1701031, NKS ref: 38-1476) — a 15×35×14mm GOST 1805 wide series bearing with K1YC9 specification. Nexans Bearings supplies both bearings — contact us for a combined quote.
Yes — always replace both inner and outer front hub bearings as a matched pair. The inner bearing (6-180502K1YC9, 15×35×14mm) and outer bearing (6-50706Y, 30×75×19mm) work together as a system. Replacing only one bearing results in mismatched wear rates and premature failure of the new bearing.
This bearing is used in the LADA VAZ-2101 (Zhiguli / Klassika) front wheel hub outer position, and likely in related Klassika models (2102–2107). Confirm fitment for other models using OEM number 2101-1701033 or contact our technical team.
