The SPWL0000000272 Needle Roller Bearing HK2536-2RS is a sealed, compact radial bearing designed for high-load, space-constrained applications in SINOTRUK Sitrak transmissions, pumps, and auxiliary drives. This OEM-grade bearing features a full complement of needle rollers and integral contact seals on both sides, providing excellent contamination protection and grease retention. As an essential element among Sinotruk Sitrak parts, the SPWL0000000272 delivers reliable performance under heavy radial loads and moderate speeds. Its compact 25mm bore and 36mm width make it ideal for tight installations where standard ball bearings would not fit. The bearing’s precision-ground raceways and hardened rollers ensure long service life and reduced friction, contributing to overall drivetrain efficiency.

The SPWL0000000272 is a drawn-cup needle roller bearing with integral rubber seals on both sides (2RS designation). Its open-end design allows for a high number of small-diameter rollers, resulting in exceptional radial load capacity relative to its cross-section. This bearing is commonly used in SINOTRUK Sitrak gearbox shafts, idler gears, and cam followers, where a compact, sealed bearing is required.
Manufactured from high-carbon chromium steel with a case-hardened outer ring, the SPWL0000000272 offers excellent wear resistance and dimensional stability. The contact seals are made of nitrile rubber, effectively retaining grease while excluding dust, water, and other contaminants. By choosing the genuine SPWL0000000272, you ensure reliable operation and extended maintenance intervals in your Sitrak drivetrain.
Integral Contact Seals (2RS): The bearing features dual nitrile rubber seals that provide effective protection against external contaminants and prevent grease leakage, making it maintenance-free for extended periods.
High Radial Load Capacity: With a full complement of needle rollers, the SPWL0000000272 offers a dynamic load rating of 18.5 kN, allowing it to handle heavy radial forces in a compact envelope.
Precision Ground Raceways: The drawn cup outer ring and the inner shaft surface are precisely ground to ensure smooth rotation, low friction, and consistent performance under varying load conditions.
Compact Design: With an outer diameter of only 32mm and width of 36mm, this bearing saves space and reduces weight compared to standard ball bearings, making it ideal for modern, lightweight transmission designs.
Additionally, the SPWL0000000272 is supplied pre-lubricated with high-quality grease, ready for installation. Its standard dimensions conform to DIN 618, ensuring interchangeability with other manufacturers’ equivalent bearings.
The following table provides all critical dimensions and performance data for the SPWL0000000272. These specifications are verified against SINOTRUK original equipment standards.
All dimensions and load ratings conform to DIN 618 and ISO 3030 standards. Always verify shaft and housing tolerances before installation to ensure proper fit and function.
The SPWL0000000272 is widely used in SINOTRUK Sitrak C7H, T7H, and A7 series vehicles, particularly in gearbox countershafts, auxiliary drive shafts, and oil pump drives. Its sealed design makes it suitable for applications where lubrication intervals are long or where external contaminants are prevalent.
This bearing is also compatible with many other heavy-duty commercial vehicle brands that use the HK2536-2RS size, making it a versatile replacement option for workshops. Always check the bore, outer diameter, and width before ordering.
Installation Guide: Clean the shaft and housing bore thoroughly. Apply a thin layer of clean grease to the shaft surface to ease installation. Press the bearing onto the shaft using a suitable sleeve – never apply force directly to the seals or cage. Ensure the bearing is seated squarely and fully against the shoulder. The sealed design does not require additional greasing prior to installation.
Maintenance Advice: Since the bearing is pre-greased and sealed, it is maintenance-free for its service life. However, during transmission overhauls, inspect the bearing for smooth rotation, seal integrity, and signs of wear. Replace the SPWL0000000272 if you notice roughness, excessive play, or damaged seals. Always replace bearings in sets when servicing gear trains to maintain balanced operation.
Using a genuine SPWL0000000272 ensures the correct seal design and grease fill, which are critical for long-term reliability. Avoid using generic bearings that may have inferior seals or improper lubrication.
Selecting the authentic SPWL0000000272 guarantees a bearing that has undergone rigorous quality controls, including dimensional verification, seal leak testing, and noise/vibration checks. Unlike aftermarket copies, this bearing offers consistent internal clearance and roller profile, ensuring optimal load distribution and minimal friction.
The SPWL0000000272 is backed by SINOTRUK’s original quality assurance, providing peace of mind for fleet operators. Users report extended gearbox life and reduced downtime after switching to genuine bearings.
The SPWL0000000272 complies with DIN 618 and ISO 3030 standards for needle roller bearings. It is manufactured under IATF 16949 certified processes, ensuring high reliability. The steel meets ASTM A295 specifications for bearing-quality material.
To avoid counterfeits, purchase this bearing from authorized SINOTRUK distributors. Genuine bearings are engraved with the part number and have a distinct seal color. Using non-certified bearings can lead to premature failure and costly transmission repairs.
Although the SPWL0000000272 is robust, some issues can occur. Seal wear or damage can allow contamination ingress – inspect seals regularly and replace the bearing if the seal is cracked or deformed. Excessive noise or vibration often indicates roller damage or insufficient lubrication; however, since it is sealed, this usually points to bearing fatigue.
If the bearing runs hot, check for over-greasing (though pre-filled, no additional grease should be added) or misalignment of the shaft. Replacing with a new SPWL0000000272 and ensuring proper shaft and housing fits will resolve most issues. Always follow torque and assembly guidelines to avoid brinelling during installation.
SINOTRUK is committed to sustainable manufacturing. The SPWL0000000272 is produced using energy-efficient processes, and the steel is sourced from recycled content. Its sealed, long-life design reduces waste and the need for frequent replacements.
By maintaining proper installation and timely replacement, you also reduce energy losses from friction, contributing to improved fuel economy. Used bearings can be recycled at metal scrapyards, supporting the circular economy.
The SPWL0000000272 Needle Roller Bearing HK2536-2RS is a compact, sealed, high-capacity bearing that delivers exceptional performance in SINOTRUK Sitrak transmissions and auxiliary drives.
