Product Specifications

Understanding the 9036338006 Part Number

The 90363 series is a Chinese national standard (GB) double row sealed ball bearing series widely used in domestic agricultural machinery and light vehicle wheel hub applications. The 38006 suffix references the associated inner ring component or complete hub unit assembly number. Contact our technical team for full specification documentation.

Dual Width Specification Explained: 33mm vs 36mm

Always specify both width values ( 33/36mm) when ordering or cross-referencing to ensure correct fitment. A bearing listed as only 33mm or only 36mm wide may be a different variant.

9036338006 vs 44300S47008 — Selecting the Right Tractor Hub Bearing

Nexans Bearings supplies both models in this double row tractor/auto wheel hub bearing series. Key differences:

Always select the bearing that matches your hub's inner diameter (bore size). If your hub shaft is 38mm, use the 9036338006. If your hub shaft is 45mm, use the 44300S47008. Contact our technical team to confirm the correct bearing for your specific tractor or vehicle model.

Why Double Row Ball Bearings for Tractor & Auto Wheel Hubs

Product Overview

The 9036338006 is a sealed double row deep groove ball bearing manufactured to OE-equivalent specifications for automotive wheel hub and agricultural tractor hub applications. The 38×72×33/36mm dimensions and double row construction make it specifically suited to the combined radial, axial, and moment loads of wheel hub positions in small-to-medium tractors and light vehicles operating under demanding agricultural and road conditions.

As the smaller-bore sibling of the 44300S47008 (45×84×40/42mm), the 9036338006 serves tractor and vehicle platforms with a 38mm hub shaft bore — providing the same double row sealed construction and OE-quality performance in a more compact envelope.

This bearing delivers:

• High radial and axial load capacity — double row ball arrangement handles the 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

• Compact single-unit design — replaces two separate single row bearings in a single, easy-to-install assembly

• OE-equivalent fit — manufactured to GB/OE specification for direct replacement of 9036338006

• 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 9036338006 (full part number / GB standard) and 38-1257 (NKS reference). The 90363 is the bearing series designation; 38006 references the associated component or assembly number.

Q: What are the exact dimensions of the 9036338006?

The dimensions are: Inner Diameter 38mm × Outer Diameter 72mm × Width 33/36mm. The dual width (33mm inner ring / 36mm overall) must both be confirmed when ordering or cross-referencing.

Q: What does the "33/36mm" dual width mean?

The 33mm is the inner ring width; the 36mm is the total assembly width including the outer ring, seals, and retaining features. Always specify both values when ordering to ensure correct fitment.

Q: What is the difference between 9036338006 and 44300S47008?

Both are double row sealed ball bearings for tractor and auto wheel hubs, but different sizes: 9036338006 has a 38mm bore (for smaller hub shafts), while 44300S47008 has a 45mm bore (for larger hub shafts). Always match the bearing bore to your hub shaft diameter. Contact us to confirm the correct bearing for your application.

Q: What equipment uses the 9036338006 bearing?

This bearing is used in small-to-medium agricultural tractor wheel hubs and light vehicle wheel hub assemblies with a 38mm bore. It is widely used in Chinese domestic tractor platforms. Contact us with your equipment make and model to confirm exact fitment.

Q: Is the 9036338006 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.

Q: What are the signs of a failing tractor wheel hub bearing?

Common symptoms include: humming, growling, or rumbling noise from the wheel that increases with speed, vibration felt through the steering or chassis, uneven tire wear, wheel play detected when rocking the wheel, or bearing overheating after operation. Replace promptly to avoid wheel hub failure during field operation.
