Product Description & Performance
Suitable Lubrication Method
Designed for grease lubrication, suitable grease nipples are provided on the bearing seat. Grease lubrication has good sealing and lubrication properties, maintains effective lubrication for extended periods, reduces wear and friction, minimizes maintenance costs, and meets demanding truck operating conditions.
Reliable Sealing Performance
Labyrinth seals are adopted with securely fastened labyrinth rings. This configuration prevents dust, impurities, and moisture from entering the bearing, protecting internal components from external contaminants, maximizing service life, and ensuring reliable performance on all road conditions.
Strong Load-Bearing Capacity
As a spherical roller bearing featuring two rows of rollers, it withstands heavy radial loads and substantial axial loads simultaneously. It provides robust structural support for heavy cargo and vehicle tare weight, ensuring dependable and secure operation.
Good Spherical Performance
Drum-shaped rollers and a spherical outer ring raceway allow the bearing to automatically adjust to shaft deflections and angular misalignment. It compensates for alignment errors caused by vehicle vibration, road irregularities, and installation tolerances, significantly reducing excess stress.
Smooth Operation
The optimized internal geometry ensures continuous, uniform contact between rollers and raceways. Smooth rolling motion substantially reduces vibration and operating noise, elevating driver comfort and lowering acoustic pollution.
Application Areas
Maintenance Guidelines
Regular Inspection
Check the condition of the bearing at scheduled intervals, monitoring for abnormal noise, elevated operating temperatures, excessive vibration, and mechanical wear.
Clean and Lubricate
Periodically clean the bearing and housing to remove dirt and particulate buildup, then apply an appropriate quantity of high-quality grease to minimize friction and wear.
Clearance Adjustment
Measure the running clearance between the bearing and housing using precision tools such as vernier calipers to confirm compliance with technical instructions. Readjust or replace components if clearance tolerances are exceeded.
Wheel Hub Product Range
Truck Wheel Hub Bearing
JITO truck wheel hub bearings consist of two internal components, which are pre-adjusted and installed directly on the wheel hub. Requiring no routine maintenance and permanently lubricated, they ensure optimal operational performance under extreme loads thanks to precise axial clearance, compact design, and premium grease formulation. Facilitates quick and convenient hub replacements on heavy-duty vehicles.
Truck Wheel Hub Bearing Unit
The truck wheel hub bearing unit is an integrated bearing assembly engineered for commercial vehicle wheel hubs. It comprises two factory-matched, pre-adjusted, permanently lubricated bearings. This integrated structure ensures straightforward assembly, requiring complete unit replacement to preserve original peak performance.
Maintenance-Free Wheel Hub Unit
The maintenance-free unit consists of a robust bearing housing paired with two precision mechanical components designed for paired assembly and disassembly. Internal matching enhances bearing endurance, providing a fast, secure, and highly efficient solution that extends service longevity.

Frequently Asked Questions (FAQ)
The 2272 truck hub bearing has a dimension specification of 360 * 650 * 410 mm, featuring a dynamic load rating of 2920 kN and a static load rating of 4900 kN, constructed from durable GCr15 chrome steel.
The bearing supports both grease and oil lubrication. Grease lubrication has a limit speed of 950 rpm and uses dedicated grease nipples on the housing, while oil lubrication allows speeds up to 1400 rpm.
The drum-shaped rollers and spherical outer ring raceway automatically accommodate angular deflection between the inner and outer rings, compensating for alignment deviations caused by frame flexing, chassis vibration, and installation variances.
It is primarily applied in commercial automotive vehicles including trucks and trailers. Additionally, it serves in ships, buses, filtration equipment, gantry milling machines, CNC drilling units, wind power equipment, and reaction equipment.
Routine maintenance consists of periodic inspection for vibration, temperature, and wear; regular cleaning to clear contaminants followed by fresh grease application; and checking axial/radial clearances with vernier calipers to match technical standards.
The bearing comes with a 12-month quality warranty against manufacturing and material defects from shipment. OEM customization options are also available for cage materials (steel, brass, nylon), custom packaging, precision grades (P0–P4), and branding.
