Detailed Parameters

Types:	Divided into single - direction (511, 512, 513, 514 series) and double - direction (522, 523, 524 series), making it convenient to choose according to specific needs.
Materials:	The rings and balls are made of high - carbon chromium steel (equivalent to SUJ2), which offers high hardness and wear resistance, ensuring top - notch quality.
Cages:	Three types of cages are available: pressed steel, machined brass, and polyamide resin. They can handle high - speed operation or environments with corrosion risks.
Load Capacity:	The dynamic load rating ranges from 5 kN to 1,200 kN, while the static load rating varies from 3 kN to 800 kN, depending on the bearing size.
Rotational Speed:	The maximum allowable speed for single - direction bearings can reach 3,000 rpm, and for double - direction bearings, it can reach 2,400 rpm, provided proper lubrication.
Operating Temperature:	Standard bearings can operate within the range of - 30°C to + 120°C. Special high - temperature models are available for extreme conditions.
Lubrication:	Both grease and oil lubrication are applicable. Models with seals or shields (such as 511ZZ, 5122RS) can prevent contamination, which is very user - friendly.
Accuracy Classes:	Manufactured in accordance with ISO standards, the default classes are P0 (Normal) and P6 (Higher Precision). For applications requiring even higher precision, P5 and P4 classes are also available.
