Chain Roller Bearing

This invention addresses the problems of chain roller bearings in coiled tubing workpieces (CTOs) prone to breakage, jamming, severe wear, and reliance on imports under harsh oilfield conditions. The aim is to develop a bearing product that meets the requirements of heavy loads, long service life, wide temperature range, and high reliability through structural optimization, internal isolation ring assembly, improved heat treatment parameters, enhanced double-lip seals, temperature-resistant lubrication adaptation, and precision machining control. This will solve tubing clamping failures and achieve domestic substitution of core components for high-end petroleum equipment.

The ultimate load-carrying capacity of chain roller bearings for petroleum intelligent equipment has core advantages such as "wide temperature resistance, high wear resistance, long life, high stability, and precise clearance control."
