Deep Groove Ball Bearings

Thin Section Deep Groove Ball Bearing

Deep groove ball bearings are one of the most common type of rolling bearings. The basic deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of cages.Deep groove ball bearing has a wide range of sizes and with simple structure, standardized machining process, reliability, durability and high-cost performance. Deep groove ball bearings can bear axial load in both radial and light axial directions and are easy to install at low maintenance costs.They have low friction torque and are optimized for low vibration and low noise, which are suitable for high-speed operation.
Applications: electric motors and generators, agriculture, material transportation, industrial gearboxes, food and beverage, industrial pumps, industrial fans, vehicles, etc.

Thin section deep groove ball bearings are the most commonly used rolling bearings. They are simple in structure and easy to use. They mainly bear radial load. When the radial clearance of the bearing is increased, it has a specific performance of angular contact ball bearings and can withstand diameters. The combined burden of direction and axial direction can also be used to bear the pure axial load when the speed is high, and thrust bearing is not suitable.

Installation Practices

Standard bearing installation practices can be used in conjunction with thin-section bearings. The inner and outer rings can be pushed into place on the housing and shaft. Installation should only be performed in a clean, contamination-free area as thin-section bearings lack seals, and grit or other contaminants could get into the bearings and disrupt their performance.

Measurement and Inspection

Due to these bearings’ large diameters and thin sections, it is necessary to address measurement and inspection. Special procedures must be followed to accurately measure the bore diameter and the outside diameter of these thin section bearings. Special gages allow three to five measurements around the circumference of the diameter. These measurements are then averaged to determine the accurate size of the bearing in the unmounted free state. This procedure allows for inherent out-of-roundness.
