Description
Basic Parameters
The CY-8H Universal Ball Bearings feature an 8mm inner diameter, constructed with high-grade GCr15 bearing steel for superior durability and load resistance. Equipped with a nylon or steel cage, these bearings offer a dynamic load capacity of 2.5kN and a static load capacity of 1.5kN, ensuring reliable performance in moderate to heavy-duty applications. With a maximum rotational speed of 20,000rpm (under oil lubrication), they are pre-lubricated with lithium-based grease as standard, suitable for operating temperatures ranging from -30°C to +120°C, while an optional high-temperature grease extends the range to -40°C to +180°C for extreme environments. Available in open, shielded, or rubber-sealed designs to protect against contaminants, the CY-8H bearings meet ISO P0 precision standards for smooth operation and positional accuracy. Ideal for industrial automation systems, robotic components, medical equipment, and food processing machinery, they also support customized solutions such as stainless steel or ceramic ball materials to address specific engineering requirements.
Product Application
Ideal for conveyor systems, robotic arms, and motion control equipment, the CY-8H bearings excel in high-speed, repetitive motion environments. Their 20,000rpm maximum speed (oil-lubricated) and ISO P0 precision ensure smooth, vibration-free operation in automated assembly lines, while the robust GCr15 steel construction withstands the dynamic loads of heavy-duty machinery. The optional rubber-sealed design protects against dust, debris, and lubricant loss, minimizing maintenance in harsh factory settings.
In medical applications such as diagnostic equipment, surgical robots, and patient handling systems, the CY-8H’s corrosion-resistant materials (available in stainless steel variants) and low-noise operation are critical. The bearings’ tight tolerance and positional accuracy support precise movements in imaging devices, while the food-grade lubrication option (when paired with FDA-compliant materials) ensures safety in medical device manufacturing or hygiene-sensitive environments.
Certified for contact with food products (when specified with FDA-approved components), the CY-8H bearings are a trusted choice for conveyors, mixers, and packaging machinery in food processing plants. The nylon cage variant reduces particulate generation, while the sealed designs prevent contamination from moisture or cleaning agents. Their ability to operate at temperatures up to +180°C (with high-temperature grease) makes them suitable for baking, canning, or sterilization equipment.
For optical stages, measurement tools, and aerospace components, the CY-8H’s low-friction design and minimal backlash are essential for maintaining positional stability. The open or shielded configurations allow for easy lubrication customization, adapting to vacuum or low-temperature environments (as low as -40°C with specialized grease), ensuring reliable performance in precision-guided systems or scientific instruments.
Engineers and OEMs benefit from the CY-8H’s modular design, which supports material and structural customization. Options include ceramic balls for reduced weight and enhanced corrosion resistance in semiconductor manufacturing, or steel cages for high-load applications in heavy machinery. Whether integrated into compact robotics, agricultural equipment, or marine systems, these bearings deliver tailored performance without compromising on standard ISO-compliant quality.
