Gearbox damage is one of the most costly breakdowns for heavy truck fleets operating long-haul transport. Damaged intermediate shaft bearings often trigger abnormal gearbox humming, unstable shifting, excessive gear wear and even complete gearbox lockup during full-load climbing. Our NCL308E single row cylindrical roller bearing is a standard replacement component for the rear end of the countershaft inside FAST gearboxes widely fitted on Sinotruk HOWO heavy trucks, trusted by transmission repair shops and global spare parts wholesalers.
This NCL308E roller bearing carries the old model code 102308E, with fixed dimensions of inner diameter 40mm, outer diameter 90mm and width 23mm, net weight 0.693kg per piece. It is specially installed at the rear position of the main box intermediate shaft of 10-speed and 12-speed FAST manual transmissions, matching all mainstream HOWO A7, T7H, TX, TH7 and HOHAN heavy-duty tractors, dump trucks and cargo vehicles. Many low-cost generic bearings adopt inferior steel raw materials and simple stamping cages, which suffer from roller peeling, cage fracture and rapid clearance enlargement after short-term heavy-load operation. Our NCL308E bearing uses high-carbon chromium bearing steel through overall quenching treatment, matched with precision brass retainer to fix each roller evenly, ensuring stable radial load bearing capacity under continuous high torque working conditions.
All NCL308E cylindrical roller bearings are processed strictly in accordance with OEM matching dimensional tolerances, the separable inner and outer ring design makes disassembly and gearbox overhaul more convenient for mechanics. Each bearing passes high-speed rotation fatigue test and radial load detection before leaving the factory, effectively avoiding premature failure caused by unqualified roundness and hardness. The surface anti-rust oil coating can resist moisture and mud erosion during chassis assembly and long-term storage, extending spare part shelf life for distributors.
Three core practical advantages make our NCL308E bearing the preferred choice for overseas transmission maintenance stores. First, fully consistent with original gearbox assembly size, zero modification needed during replacement, greatly cutting workshop disassembly and installation labor time. Second, high rigidity roller structure reduces gear vibration and abnormal noise, slowing down wear of synchronizer and gear teeth to lower long-term fleet maintenance expenditure. Third, we maintain continuous large spot inventory of NCL308E all year round, supporting single-piece orders for emergency gearbox repair and tiered discount bulk orders for regional parts suppliers, neutral export packaging is available for local secondary resale needs.
NCL308E roller bearing only fits FAST series heavy-duty truck gearbox intermediate shaft rear position, it cannot be used as hub bearing or engine bearing replacement. When overhauling the gearbox, it is recommended to replace the intermediate shaft bearing, input shaft bearing and all worn synchronizer parts together to avoid repeated disassembly work. If you cannot confirm matching compatibility with your truck gearbox model, you can provide vehicle VIN or gearbox serial number, our technical team will complete verification within 24 working hours.
Cutting corners by installing low-quality gearbox bearings will easily lead to expensive full gearbox replacement. Our standard NCL308E cylindrical roller bearing meets factory assembly quality standards, providing durable and cost-effective transmission replacement solution for all global HOWO heavy truck operators.
