Coiled Tubing Injector Roller bearing

Product Overview

Coiled Tubing (CT) Bearing Roller is a professional core guide and drag reduction component specially designed for oilfield coiled tubing operations. It is widely applied in CT injectors, wellhead guiding systems, downhole extended-reach operations and tubing winding & unwinding equipment. Adopting an integrated bearing structure instead of traditional sliding friction design, it greatly reduces tubing drag force, avoids outer wall scratch, wear and deformation, and effectively improves downhole operation depth and working efficiency.

Manufactured with high-strength alloy steel or stainless steel forging and fully sealed heavy-duty precision bearings, our CT rollers feature high temperature resistance, high pressure resistance, anti-corrosion, impact resistance and self-aligning anti-deflection performance. The precisely polished arc groove fits the tubing surface in 360° adaptive contact, compensating installation errors and tubing swing to eliminate jamming, deviation and pipe sticking. Pre-filled with special long-life oilfield grease, the roller stably operates in complex downhole environments with high temperature, mud, acid, alkali and oil-water mixture, realizing long-term maintenance-free service.

Complying with strict oilfield industrial standards, this product fits mainstream CT sizes from 2-3/8 inch to 9-5/8 inch and is fully interchangeable with major branded coiled tubing equipment. It reduces friction coefficient by 40%-60%, extending the service life of coiled tubing and machinery. Ideal for deep well, long-reach, high-corrosion and HPHT oil & gas operations. Custom non-standard sizes, special grooves and high-strength materials are available for customized harsh working conditions.

English Key Features

• Ultra-Low Drag & Tubing Protection: Rolling friction replaces sliding friction to reduce drag force and avoid tubing scratch, deformation and fatigue damage

• Self-Aligning Anti-Deflection Design: 360° adaptive arc groove adapts to tubing swing and installation error without deviation or pipe jamming

• Fully Sealed Heavy-Duty Protection: Multi-layer bearing seal blocks mud, dust, oil, water and acid-alkali media to prevent failure

• Oilfield-Grade Weather Resistance: High temp, high pressure, impact and corrosion resistant for extreme downhole conditions

• Long-Term Maintenance-Free Operation: Special oilfield anti-aging grease prevents leakage and ensures stable long-term operation without lubrication

• Extended-Reach Operation: Effectively reduces friction and improves downhole lateral reach and construction efficiency

• High Interchangeability & Easy Replacement: Standard oilfield sizes compatible with mainstream CT equipment for easy installation and low replacement cost

• High-Strength Durability: Integral forging process provides high hardness and toughness against long-term heavy-load deformation and damage

Application Scenarios

• Coiled Tubing Injector Equipment: Matches wellhead injection guiding system to stably convey tubing and reduce equipment load loss
