Engineered for extreme durability, the 6019-Z deep groove ball bearing with dust cover stands as a premium replacement component for Howo/Sitrak truck parts and commercial vehicle drivelines. This bearing delivers exceptional load capacity, low friction, and reliable sealing – vital for the heavy haulage and construction sectors. The 6019-Z ensures minimal maintenance intervals and consistent performance under high-speed or high-torque conditions.
The 6019-Z bearing is manufactured with high-grade chromium steel, precision-honed raceways, and a non-contact metal dust cover that effectively shields against contaminants while retaining lubrication. This design reduces wear, heat generation, and noise – a decisive advantage for fleets relying on Howo and Sitrak trucks. Whether you operate in dusty mining environments or on highways, the 6019-Z provides the resilience that professional drivers demand.
This 6019-Z bearing features a single-shielded design that prevents abrasive particles from entering the rolling elements, while the deep-groove geometry accommodates both radial and moderate thrust loads. Compared to open bearings, the dust cover extends service life by up to 40% in typical truck axle and gearbox applications.
All dimensions conform to ISO 15 and DIN 625-1 standards. The 6019-Z is interchangeable with OEM references and fits directly into Howo/Sitrak wheel hubs, transmission countershafts, and differential carriers.
The 6019-Z bearing is widely used in front and rear axle hubs, gearbox output shafts, and belt tensioner pulleys on Howo A7, Howo T7, Sitrak C7H, and Sitrak TGA series. Its robust outer ring and precision-ground balls ensure smooth rotation even under heavy cross-loads typical of dump trucks and concrete mixers. Fleet operators report extended overhaul intervals after replacing original bearings with the 6019-Z due to its superior seal integrity.
This bearing also serves as a direct replacement for OEM numbers 6019-Z (ZZ variant) in various Chinese and European heavy-truck platforms, making it a versatile stock-keeping unit for workshops.
Independent lab tests confirm that the 6019-Z maintains its radial clearance within C3 tolerance after 500 hours of cyclic loading, ensuring consistent performance in stop-and-go urban traffic and long-haul motorway runs.
Always press or tap the bearing into place using a fitting sleeve that applies force evenly to the outer ring. Avoid hammering directly on the shield to prevent distortion. For Howo/Sitrak hub applications, torque the retaining nut to 250–280 N·m and check endplay with a dial gauge.
Re-grease intervals for the 6019-Z should be scheduled every 50,000 km under normal service, or more frequently in high-moisture environments. Use NLGI grade 2 lithium-based grease; do not overpack, as excess grease may increase operating temperature.
When storing the 6019-Z bearing, keep it in its original packaging in a dry, vibration-free area. Rotate the bearing periodically to redistribute the grease and prevent brinelling marks on the raceways.
Every 6019-Z bearing is manufactured under IATF 16949 and ISO 9001 certified facilities. 100% dimensional inspection and noise testing (VIB III grade) are performed before packaging. The dust cover is corrosion-resistant and passes 96-hour salt spray testing (ASTM B117). This rigorous quality control ensures that every bearing matches the original equipment specifications for Howo/Sitrak trucks.
By reducing friction and maintaining lubricant integrity, the 6019-Z bearing contributes to lower fuel consumption and reduced CO₂ emissions – a key consideration for modern fleets. The extended service life (up to 1.5× longer than generic alternatives) translates into fewer bearing changes, less waste, and reduced downtime, offering a compelling return on investment.
Always verify the bearing dimensions with your existing component. The 6019-Z is a non-separable bearing, and its dimensional interchangeability covers most heavy-duty truck applications that require a 95×145×24 mm shielded bearing.
With its robust design, precision engineering, and proven performance in Howo/Sitrak trucks, the 6019-Z deep groove ball bearing with dust cover is the smart choice for workshop professionals and fleet managers who demand reliability, longevity, and cost-efficiency. Upgrade your driveline with the 6019-Z – the bearing that keeps your heavy-duty trucks moving.
