7311A5hU9 Cryogenic bearings

The high-performance 7311A5hU9 low-temperature bearing developed by MONTON is used for low-temperature pumps in liquid nitrogen environments at -196 ℃. The ring is made of high nitrogen stainless steel, the ball is made of imported silicon nitride Si ∝ N ₄ material, and the cage is made of non-metallic materials with self-lubricating, wear-resistant, and low-temperature resistance, with excellent low-temperature strength and anti brittle fracture ability. Commonly used terms include liquefied natural gas (LNG) pumps, liquid nitrogen/liquid hydrogen/liquid oxygen pumps, spacecraft liquid fuel pumps, and rocket engines. Bearings have properties such as low temperature resistance, wear resistance, and corrosion resistance, and can maintain stable operation in low temperature environments. They also have certain load-bearing capacity and good rotational accuracy.
