What do different bearing grease colors mean?
Each bearing grease color indicates specific performance traits and usage: black grease offers wear resistance under extreme pressure, red grease handles high temperatures, blue grease is waterproof for marine environments, green grease is biodegradable and used in agriculture, white grease is food-safe and
Truck wheel bearings should generally be replaced in pairs on the same axle, even if only one has failed. This ensures balanced wear, prevents future breakdowns, and minimizes repair downtime. For high-mileage or fleet vehicles, replacing all wheel bearings during scheduled service enhances long-term safety and cost-efficiency.
To determine a truck wheel bearing failure, mechanics check for abnormal noises, excessive wheel play, rough rotation, high hub temperatures, grease contamination, and bearing endplay using dial indicators. A visual inspection of the rollers and races confirms internal damage. Accurate diagnosis is essential for safety and preventing costly truck repairs.
Trucks use various types of bearings across key components to ensure durability and performance. The most common truck bearings include tapered roller bearings in the front and rear wheel hubs, cylindrical and needle roller bearings in the transmission, tapered roller bearings in the differential, and ball bearings in the driveshaft
Used ball bearings from Alibaba may appear cost-effective, but they pose serious risks due to unknown wear, lack of traceability, and unverified performance. Without documented inspection and reconditioning, these bearings are unsuitable for industrial use. A professional bearing application engineer explains why second-hand bearings rarely offer long-term value and outlines
Used papermaking equipment bearings may offer lower initial purchase prices, but they rarely save costs in the long run. Due to the demanding operating conditions in paper mills—such as high speed, temperature, and humidity—used bearings are more prone to premature failure, leading to unplanned downtime, costly repairs, and production losses.
To select and maintain bearings for textile machinery, choose the right bearing type based on speed, load, precision, and operating environment. Common types include angular contact ball bearings for spinning machines, deep groove ball bearings for looms, and spherical roller bearings for dyeing units. Maintenance must focus on proper lubrication,
To select and maintain bearings for logistics transmission equipment, you must match the bearing type to the equipment’s load, speed, and environmental conditions—such as dust, vibration, and temperature. Deep groove ball bearings, spherical roller bearings, and angular contact bearings are commonly used in conveyors, sorters, and AGVs. Proper sealing, lubrication,
To match the right bearing for an excavator, you must first identify the bearing’s location—such as slew ring, travel motor, or hydraulic pump—then select a bearing type that meets the machine’s load requirements, environmental conditions, sealing needs, and clearance specifications. Proper material selection, heat treatment, and sealing design are essential
Motor bearing lubrication is essential for reducing friction, preventing wear, dissipating heat, and extending bearing life. This operation guide explains the correct lubrication practices, including selecting the right grease or oil, applying it properly, and setting the optimal lubrication frequency based on motor conditions. Following these steps helps end users
