This bearing is a premium solution for SINOTRUK Sitrak trucks, providing reliable support for wheel hubs, differentials, and pinion shafts. Its tapered design allows it to handle combined radial and thrust loads, making it ideal for the demanding forces encountered in heavy haulage and off-road applications. The bearing features a separable cone and cup assembly, which simplifies installation and adjustment of preload.
Constructed from high-quality chromium steel with a uniform microstructure, this component offers exceptional fatigue strength and wear resistance. Its rollers are precisely profiled to optimize load distribution and reduce edge stress, ensuring consistent performance over millions of revolutions. Choosing the genuine SPCS0000000292 guarantees that your drivetrain operates with minimal friction, reduced heat generation, and extended component life.
High Load-Carrying Capacity: The bearing features a large roller diameter and optimized contact angle, enabling it to withstand extreme radial and axial loads typical of heavy-duty truck axles.
Premium Material & Heat Treatment: Manufactured from case-hardened SAE 52100 steel with controlled carburizing, the bearing achieves high surface hardness (HRC 60-64) while maintaining a tough core to resist shock loading.
Precision-Ground Raceways: The inner and outer rings are super-finished to Ra ≤ 0.2 µm, reducing friction and allowing for higher rotational speeds with minimal temperature rise.
Interchangeable Dimensions: The bearing conforms to ISO 355 and DIN 720 standards, ensuring compatibility with industry-standard hubs and shafts, simplifying replacement logistics.
Additionally, this bearing includes a durable steel cage that retains rollers evenly, preventing skewing and minimizing noise. Its black oxide coating provides temporary corrosion protection during storage and handling, making it a reliable choice for workshops and field maintenance.
The following table lists all critical dimensions and performance data for this bearing. These specifications are verified against SINOTRUK’s original equipment requirements.
All dimensions and ratings are in accordance with ISO 281 for bearing load ratings. Always verify fitment with your axle assembly drawing before installation.
This bearing is primarily used in SINOTRUK Sitrak C7H, T7H, A7, and H7 series trucks, particularly in front wheel hubs, rear axle pinion supports, and differential side bearings. Its robust design also suits heavy-duty trailers, agricultural machinery, and construction equipment that use the same bearing size.
This component is interchangeable with many industry-standard part numbers, making it a versatile replacement option for workshops servicing multiple brands. Always check the bore, outer diameter, and width to confirm compatibility.
Installation Guide: Before installation, inspect the shaft and housing for burrs or damage. Apply a thin layer of high-quality bearing grease to the races and rollers. Press the cone onto the shaft using a suitable mandrel – never hammer directly. Similarly, press the cup into the housing bore. Adjust preload according to the manufacturer’s specifications using a torque wrench or dial indicator.
Maintenance Advice: Inspect the bearing during wheel or differential overhauls. Look for signs of spalling, discoloration, or pitting. Replace if any damage is visible. Always replace bearings in sets (both sides) to maintain balanced performance. Use the recommended grease type and quantity to avoid overheating and premature failure.
Using a genuine SPCS0000000292 ensures correct internal clearance and roller geometry, which are essential for proper load distribution. Avoid mixing components from different manufacturers, as this can lead to improper fit and early failure.
Selecting the authentic SPCS0000000292 guarantees a bearing that has passed rigorous quality tests, including dimensional accuracy, material hardness, and fatigue life validation. Unlike generic alternatives, this bearing is designed to match the exact load and speed characteristics of SINOTRUK Sitrak axles, ensuring optimal performance and safety.
This bearing is also backed by SINOTRUK’s original quality assurance program. Fleet operators who use it report longer overhaul intervals, reduced wheel-end temperature, and lower maintenance costs over the vehicle’s lifetime.
This bearing complies with ISO 355 and DIN 720 dimensional standards. It is manufactured under IATF 16949 quality management systems and meets the performance requirements of ASTM A295 for bearing steel. Each unit is 100% inspected for bore, OD, width, and running accuracy.
To avoid counterfeits, purchase this bearing from authorized distributors. Genuine bearings are laser-engraved with the SINOTRUK logo and part number. Using unverified bearings can lead to premature failure and unsafe vehicle operation.
While this bearing is designed for long life, certain problems can occur. Excessive wear or brinelling often results from incorrect preload or contamination – always use clean grease and proper tools. If you notice abnormal noise or vibration, inspect the bearing immediately. Replace with a new SPCS0000000292 if the rollers or raceways show scoring.
Overheating is usually caused by insufficient lubrication or over-tightening. Follow the recommended torque values and grease intervals. If a bearing fails repeatedly, check the axle alignment and housing condition. Addressing these root causes will extend the life of your component.
SINOTRUK is committed to sustainable manufacturing. This bearing is produced using energy-efficient processes, and the steel is sourced from recycled material. Its long service life reduces the frequency of replacements, lowering overall waste and resource consumption.
By maintaining proper lubrication and timely replacement, you also reduce energy losses from friction, contributing to lower fuel consumption and CO₂ emissions. Used bearings can be recycled at metal scrapyards, supporting the circular economy.
This tapered roller bearing is a cornerstone of reliable drivetrain performance in SINOTRUK Sitrak trucks. With its robust construction, precise geometry, and high load capacity, it ensures smooth and durable operation in the most demanding transport and off-road applications.
