Non-standard Series Spherical Roller Bearings are personalized bearing solutions tailor-made by Dalian Jinyu Bearing for special working conditions and equipment that cannot be adapted by conventional standard bearings.
We focus on medium and large-sized, giant non-standard spherical roller bearings with an inner diameter of 100mm and above, inheriting the high-quality genes of standard series such as 222 and 223. Meanwhile, according to customers' specific needs, we make customized adjustments in terms of size, structure, material, precision, etc. They are widely used in fields such as mining, crushers, metallurgy, heavy machinery, solving the non-standard adaptation problems in equipment operation.
As a factory-type trading company, we have our own production base, which can realize full-process control from drawing design, raw material procurement, production and processing to finished product inspection, ensuring the performance and stability of non-standard bearings and meeting customers' personalized and high-demand usage needs.
