Silent Electric Motor Bearing 6004 6203 6304 with C2 Clearances For Agricultral Machinery

Different mechanical equipment has different requirements for bearings. For example, high-speed rotating equipment requires bearings with low friction and high limit speed, while heavy machinery requires bearings that can withstand heavy loads. Because of its good performance and wide applicability, deep groove ball bearings are widely used in various mechanical equipment.

We, Cixi Kent Bearing Co., Ltd use high carbon chromium bearing steel (GCr15) for producing high quality deep grooove ball bearings, and we also accept customed material such as stainless steel to make bearings.
