In the demanding world of heavy-duty trucking, protecting critical suspension components from contaminants is paramount for longevity. This is where premium SANY parts prove their worth. The Bogi Bush Outer Seal, bearing the specific OEM part number 131402010050A017, is a precision-engineered sealing solution designed specifically for the bogie pivot bushings on SANY trucks and compatible heavy vehicles.
Its primary function is to create a robust, flexible barrier that excludes dirt, mud, water, and road grit from entering the bogie bush assembly, while simultaneously retaining vital lubricants. By preventing contamination and preserving lubrication, the genuine 131402010050A017 seal directly contributes to reduced wear, smoother articulation, and extended service intervals for the entire bogie suspension system, ensuring reliable performance under the toughest conditions.

The bogie suspension is the workhorse of a heavy truck’s chassis, responsible for absorbing immense loads and terrain shocks. At the heart of its articulation points are the bogie bushes or pivot bushings. The SANY Bogi Bush Outer Seal, part number 131402010050A017, is the first line of defense for these components.
It is meticulously designed to fit over the outer face of the bush housing, forming a dynamic seal around the moving pivot pin or bolt. Without the protective function of the 131402010050A017, abrasive particles would quickly infiltrate the bushing, acting as grinding paste that accelerates wear on both the metal pin and the rubber or polyurethane bush material. This leads to excessive clearance, knocking noises, imprecise axle alignment, and ultimately, catastrophic bushing failure.
Performance Insight: A compromised outer seal allows grease to be washed out or forced out during operation. This loss of lubrication leads to dry metal-on-metal or metal-on-bush contact, generating excessive heat and rapid deterioration. Regular inspection of the 131402010050A017 seal for cracks, tears, or deformation is a simple yet highly effective predictive maintenance practice that can prevent costly bogie overhauls.
The 131402010050A017 seal typically features a sophisticated multi-lip design. Primary lips maintain constant contact with the moving shaft, scraping off contaminants. Secondary lips act as dust guards and grease retainers. This multi-stage defense ensures superior sealing integrity compared to single-lip designs, making it ideal for off-road and construction site environments where particulate contamination is extreme.
Crafted from a specialized nitrile rubber (NBR) or advanced polyacrylate compound, this seal offers exceptional resistance to grease, oils, ozone, and temperature fluctuations. The material remains flexible in sub-zero conditions while resisting hardening and cracking in high-heat environments near brakes, ensuring the 131402010050A017 performs reliably from -40°C to over 120°C.
To withstand high pressure and prevent roll or twist during installation and operation, the seal often incorporates a metal casing or a rigid polymer reinforcement ring. This gives the 131402010050A017 its precise shape retention, ensures a snug fit in the housing bore, and allows it to handle the axial and radial loads present in the bogie pivot point without deformation.
Investing in the genuine SANY Bogi Bush Outer Seal (131402010050A017) delivers substantial operational and financial advantages. The most direct benefit is the dramatic extension of bogie bush service life. By maintaining a clean, lubricated environment, pivot points articulate smoothly with minimal friction. This translates to more consistent axle alignment, better tire wear patterns, and improved vehicle stability and handling. For fleet managers, this means fewer unscheduled downtime events for suspension repairs and longer intervals between major bogie rebuilds.
Furthermore, a well-sealed bogie system reduces the frequency of grease purging and re-lubrication. The seal effectively retains the applied grease, leading to less consumable waste and lower maintenance labor costs. The prevention of abrasive wear also protects the more expensive pivot pins and housing bores from damage, avoiding the need for complex machining or replacement of these heavy-duty components. In essence, the humble 131402010050A017 seal is a low-cost component that safeguards high-value assets, offering an exceptional return on investment.
The table below details the essential technical parameters for the SANY Bogi Bush Outer Seal, OEM part number 131402010050A017. These specifications are critical for correct part identification, verification of compatibility, and ensuring optimal performance in your specific application.
Replacing the Bogi Bush Outer Seal (131402010050A017) is a task best performed during scheduled bogie maintenance or when replacing the bush itself. Begin by thoroughly cleaning the external area around the bogie housing to prevent dirt ingress. Safely support the axle and remove the pivot bolt to release the bogie beam. The old seal can be carefully pried out using a suitable seal removal tool, taking care not to score the seal housing bore. Before installing the new 131402010050A017 seal, clean the housing bore and the pivot pin surface meticulously. Lightly lubricate the outer metal casing of the new seal and the sealing lips with the approved grease.
Installation Tip: Use a seal driver or a appropriately sized socket that contacts the outer metal rim of the seal. Drive the seal in squarely and evenly until it is fully seated against the housing shoulder. Avoid hammering directly on the rubber sealing element, as this can damage the lips. After installation, re-lubricate the bush assembly through the grease nipple before reassembling the pivot joint.
Visual Inspection: During routine service, visually inspect the 131402010050A017 seal for any signs of cracking, hardening, tearing, or permanent deformation. Check for grease leakage around the seal periphery, which indicates the sealing lip has lost tension or the seal is not properly seated.
Grease Contamination: If grease purged from the nipple appears dirty or gritty, it is a strong indicator that the outer seal has failed and allowed contaminants to enter. This necessitates immediate replacement of the 131402010050A017 seal and a full flush and re-lubrication of the bush cavity.
Suspension Noises: Excessive knocking, creaking, or clunking from the bogie area during articulation (especially when unladen) can be a symptom of a worn bush due to seal failure. While not the direct source of noise, a failed seal accelerates the wear that causes it.
Preventive Schedule: It is advisable to inspect these seals every 25,000 to 50,000 km or during every major service. Proactive replacement of the 131402010050A017 seal when the bush is serviced is a cost-effective best practice that ensures long-term suspension health.
Selecting the authentic SANY Bogi Bush Outer Seal, part number 131402010050A017, is a decision that guarantees fit, function, and durability. Counterfeit or generic seals may look similar but often use inferior rubber compounds that harden, crack, or degrade quickly when exposed to grease, ozone, and temperature extremes. Their dimensions may not be precise, leading to poor seating, easy dislodgement, or inadequate lip contact. The genuine 131402010050A017 is engineered to the exact tolerances of SANY bogie systems, ensuring optimal compression and sealing force for the lifetime of the bushing.
Moreover, using genuine SANY parts maintains your vehicle’s warranty compliance and supports the OEM ecosystem of quality. Fleet operators benefit from the predictable performance and extended service life, which reduces total lifecycle costs and minimizes vehicle downtime. Trust in the engineering and rigorous testing behind every genuine 131402010050A017 seal to protect your valuable equipment.
The SANY Bogi Bush Outer Seal (OEM 131402010050A017) is a small yet critically important component that plays an outsized role in the health and longevity of your truck’s bogie suspension. By effectively sealing out contaminants and retaining lubricant, it ensures smooth articulation, reduces wear, and prevents premature failure of costly pivot components.
For optimal results, always pair the replacement of the 131402010050A017 seal with a thorough cleaning and re-greasing of the bogie bush assembly. Source this seal from authorized SANY parts distributors to ensure you receive the genuine article, and adhere to recommended maintenance intervals. Protecting your suspension with the correct seal is a simple step towards achieving maximum vehicle uptime and reliability.
