Product Description & Key Characteristics
Designed for grease lubrication with dedicated grease nipples on the bearing seat. Delivers optimal sealing and lubrication, maintaining lubrication integrity over extended periods, reducing wear and friction, lowering maintenance costs, and meeting truck operational demands across tough conditions.
Adopts firmly fastened labyrinth seals with labyrinth rings. This configuration prevents dust, debris, and moisture ingress, shielding the bearing from contaminants, prolonging service life, and securing reliable operation across various harsh road conditions.
Engineered as a spherical roller bearing with two rows of rollers, capable of supporting heavy radial loads and concurrent axial loads. Perfectly supports heavy vehicle self-weight and cargo weight to maintain truck safety.
Features drum-shaped rollers and a spherical outer ring raceway that adapt to shaft deflection and mounting misalignment. Mitigates excess stress caused by vehicle vibration, uneven terrain, and installation discrepancies.
Optimized structural design ensures smooth contact between rollers and raceways. Greatly reduces vibration and operating noise, improving driving comfort, mitigating driver fatigue, and minimizing ambient noise emission.
Application Areas
Mainly used in commercial vehicles such as trucks and trailers, and widely utilized across ships, buses, filtration equipment, gantry milling machines, CNC drilling machines, wind energy equipment, and chemical reaction equipment.
Bearing Maintenance
Periodically evaluate bearing status, observing for abnormal noises, temperature spikes, increased vibration levels, and raceway wear.
Routinely clean bearing and housing assemblies to eliminate debris, applying clean, premium grease to control friction and wear.
Measure operational clearance using precision tools (e.g., vernier calipers) to match specified tolerances. Timely adjust or replace worn components if gaps deviate.
