Auto Wheel & Tractor Bearing 9036343008 (38-1253) | Double Row Ball Bearing 43×82×45mm — Wheel Hub & Agricultural Tractor, OEM & Wholesale Supply

Product Specifications

Understanding the 9036343008 Part Number

The 90363 series covers multiple bore sizes within the same double row sealed ball bearing family. The 9036343008 (43mm bore) and 9036338006 (38mm bore) both belong to the 90363 series — sharing the same series design principles but serving different shaft bore sizes. The 43008 suffix identifies the 43mm bore configuration and its associated component number. Contact our technical team for full specification documentation.

⚠️ Critical Distinction: Two 43mm Bore Variants — 79mm and 82mm OD

Nexans Bearings supplies two different double row sealed ball bearings with the same 43mm bore but different outer diameters. These are not interchangeable:

⚠️ CRITICAL WARNING: Both bearings have the same 43mm bore and the same 800g weight, but have different outer diameters (82mm vs 79mm) and different widths (45mm vs 38/41mm). Installing the wrong bearing will result in incorrect hub housing fit. Always confirm your hub housing bore before ordering: 82mm housing → 9036343008 / 79mm housing → 44300S5A008. Contact our technical team if you are unsure which variant your equipment requires.

90363 Series: 38mm and 43mm Bore Variants

Within the GB 90363 series, Nexans Bearings supplies two bore sizes:

Both bearings belong to the GB 90363 series but serve different shaft bore sizes. Select by matching the inner diameter to your hub shaft: 38mm shaft → 9036338006 / 43mm shaft → 9036343008 (if housing bore is 82mm).

Vehicle & Equipment Compatibility

The 9036343008 double row ball bearing is used across a range of automotive and agricultural equipment wheel hub applications requiring a 43mm bore and 82mm housing bore:

Please confirm exact fitment using part number 9036343008 or contact our technical team with your equipment make, model, and year. For 43mm shaft equipment, always confirm the hub housing bore (79mm or 82mm) to select between 9036343008 and 44300S5A008.

Why Double Row Ball Bearings for Tractor & Auto Wheel Hubs

Product Overview

The 9036343008 is a sealed double row deep groove ball bearing manufactured to OE-equivalent specifications for automotive wheel hub and agricultural tractor hub applications. With a 43mm bore, 82mm outer diameter, and 45mm single width, it belongs to the GB 90363 series — the same series as the 9036338006 (38mm bore, 72mm OD) — and is the larger-bore sibling within that series.

For buyers sourcing 43mm bore wheel hub bearings, the 9036343008 is the 82mm OD variant, distinct from the 44300S5A008 (43mm bore, 79mm OD) in the GB 44300S series. Both weigh 800g but serve different hub housing specifications — confirming the hub housing bore is essential before ordering.

This bearing delivers:

• Correct hub housing fit — 82mm OD precisely matches the hub housing bore for equipment specifying the 9036343008

• High radial and axial load capacity — double row ball arrangement handles combined loads of loaded tractor and vehicle wheel hubs

• Moment load resistance — double row geometry resists tilting forces from uneven terrain and field operation

• Superior contamination resistance — sealed construction blocks dust, mud, and moisture in agricultural and road environments

• Excellent grease retention — factory pre-lubricated, sealed for life under normal operating conditions

• Robust 800g construction — heavy-duty build for demanding mid-to-heavy tractor and vehicle hub applications

• OE-equivalent fit — manufactured to GB/OE specification for direct replacement of 9036343008

• 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.

Frequently Asked Questions

Q: What are all the part numbers for this bearing?

This bearing is referenced as 9036343008 (full part number / GB standard) and 38-1253 (NKS reference). The 90363 is the bearing series; 43008 references the 43mm bore configuration and associated component number.

Q: What are the exact dimensions of the 9036343008?

The dimensions are: Inner Diameter 43mm × Outer Diameter 82mm × Width 45mm.

Q: What is the difference between 9036343008 and 44300S5A008?

Both have a 43mm bore and weigh 800g, but different outer diameters and widths: 9036343008 = 82mm OD, 45mm width (GB 90363 series) / 44300S5A008 = 79mm OD, 38/41mm width (GB 44300S series). They are not interchangeable. Confirm your hub housing bore: 82mm → 9036343008 / 79mm → 44300S5A008.

Q: How do I choose between 9036343008 and 44300S5A008 for my 43mm shaft?

Both fit a 43mm shaft. The difference is the hub housing bore: measure your hub housing — 82mm housing → 9036343008 / 79mm housing → 44300S5A008. Contact our technical team with your equipment details if you are unsure.

Q: How does the 9036343008 relate to the 9036338006?

Both belong to the GB 90363 series but have different bore sizes: 9036338006 = 38mm bore, 72mm OD / 9036343008 = 43mm bore, 82mm OD. Select by matching the inner diameter to your hub shaft size.

Q: Why does the 9036343008 have a single width (45mm) while some other bearings have dual widths?

The single 45mm width reflects the GB 90363 series design at the 43mm bore size — the inner ring and overall assembly width are specified as a unified dimension. This is consistent with the 44300SAA003 (38mm bore, 40mm single width) in the range, while the 90363/90369 series 38mm bore variants use dual widths.

Q: What equipment uses the 9036343008 bearing?

This bearing is used in medium agricultural tractor wheel hubs and light-to-medium commercial vehicle wheel hub assemblies with a 43mm bore and 82mm hub housing bore. Contact us with your equipment make and model to confirm exact fitment.

Q: Is the 9036343008 pre-lubricated?

Yes. The bearing is factory pre-lubricated with grease and sealed on both sides. Under normal operating conditions, no relubrication is required during the bearing's service life.
