Japan Bearing Dimension 30.6 x59x16.6 mm– Automobile Gearbox Bearing 031BC05-C3
Exact Fit for Transmission Main Shaft Applications
This automobile gearbox bearing lugs the component number 031BC05-C3 and matches the exact Japanese typical dimension of 30.6 mm inner diameter , 59 mm outer diameter , and 16.6 mm width . It is constructed for use in transmission primary shaft systems where reliability and smooth operation matter a lot of.
The bearing uses state-of-the-art steel and tight manufacturing tolerances to make certain constant performance under heavy lots and high speeds. Its C3 inner clearance offers it extra area in between the races and rolling components. This design assists the bearing run cooler and last longer in atmospheres with temperature level adjustments or small imbalance.
Why choose this bearing?
It fits directly into many Japanese-made transmissions without modification. Mechanics and rebuilders depend on it due to the fact that it satisfies initial devices specifications. The surface area finish and geometry are meticulously managed so the bearing seats effectively and rotates with very little rubbing.
Durability you can count on
Every device undergoes rigorous quality checks prior to leaving the manufacturing facility. The raceways are brightened to lower wear, and the cage holds the rollers securely in place. This reduces noise and vibration during gear changes and travelling.
Usual applications
This bearing operates in a variety of auto and light vehicles that utilize handbook or automated hands-on gearboxes. Constantly check your car’s service handbook to verify part compatibility prior to installation.
Usage only clean devices and proper press-fit methods when mounting. Avoid hammering straight on the bearing rings. A right install safeguards the bearing and prolongs its life span. Keep the bearing secured until you prepare to use it to prevent contamination from dust or dampness.

Applications of Japan Bearing Dimension 30.6 x59x16.6 mm– Vehicle Transmission Bearing 031BC05-C3
Engineered for Precision in Transmission Equipments
The 031BC05-C3 transmission major shaft bearing is a high-grade element built to exact Japanese engineering requirements. It gauges 30.6 mm inner diameter, 59 mm outer size, and 16.6 mm size , making it optimal for usage in compact yet demanding automobile gearbox configurations. This bearing plays an essential role in sustaining the main shaft inside guidebook and automated hand-operated transmissions.
Dependable Performance in Daily Driving and Heavy Use
This bearing is frequently located in auto, light trucks, and some efficiency lorries. It manages radial and axial loads smoothly throughout equipment shifts and continuous turning. The C3 interior clearance offers it additional room to operate under heat expansion, which typically occurs throughout lengthy drives or stop-and-go traffic. That implies much less risk of confiscating or early wear.
Producers choose this details size and model because it fits securely within tight transmission real estates without compromising stamina. Its style lowers vibration and sound, aiding chauffeurs take pleasure in a quieter, smoother adventure. Over time, that likewise reduces maintenance expenses and prolongs the life of relevant parts like synchronizers and gears.
Constructed to Last with Consistent Quality
Made from top-quality chrome steel and precision-ground races, the 031BC05-C3 withstands tiredness and surface area damages also under repeated stress and anxiety. Each device goes through stringent quality checks prior to leaving the manufacturing facility. Specialists trust it throughout rebuilds because it matches original devices specs very closely. It works well with basic transmission oils and does not require special setup devices.
Whether you’re replacing a used component or constructing a new transmission assembly, this bearing delivers reliable support where it matters most– best at the heart of your car’s power transfer system.

5 FAQs of japan bearing size 30.6x59x16.6 mm Auto Gearbox Bearing 031bc05-c3 Transmission Main Shaft Bearing 031BC05
Frequently Asked Questions: Japan Bearing Size 30.6x59x16.6 mm (Model 031BC05-C3)
What vehicles use the 031BC05-C3 bearing?
This bearing fits many Japanese automatic transmissions. It is commonly found in models from Toyota, Nissan, and Honda. Always check your vehicle’s service manual or part number before buying.
What do the numbers 30.6x59x16.6 mm mean?
These are the exact dimensions of the bearing in millimeters. The first number (30.6) is the inner diameter. The second (59) is the outer diameter. The third (16.6) is the width. Matching these sizes ensures proper fit and function.
What does “C3” stand for in 031BC05-C3?
“C3” refers to the internal clearance of the bearing. A C3 clearance is slightly larger than standard. This helps with high-speed operation or higher temperatures. Do not use a C3 bearing unless your gearbox requires it.
Is this bearing made in Japan?
Yes. This specific model is produced by top Japanese bearing manufacturers. These brands follow strict quality control. They meet original equipment (OE) standards for performance and durability.
How can I tell if my bearing needs replacing?
Listen for unusual noises like whining or grinding during gear shifts. Check for transmission slipping or delayed engagement. If you notice any of these signs, inspect the main shaft bearing.
