GE 220 TXA-2LS Steel / PTFE Fabric Spherical Plain Bearing 220x320x135mm

1. Product Overview

GE 220 TXA-2LS belongs to metric GE series maintenance-free spherical plain bearing, standard core dimension inner bore d=220mm, outer diameter D=340mm, overall width B=135mm.

Suffix parameter explanation:

• TXA: Self-lubricating composite sliding layer on inner ring outer surface, low friction coefficient, no frequent refueling required for long-term operation;
• 2LS: Double lip rubber contact sealing structure on both sides of outer ring, fully wrap the matching clearance between inner and outer rings, effectively block dust, mud, metal debris and splash water intrusion, prevent internal solid lubricant loss.

Integrated monolithic outer ring + spherical inner ring structure, spherical sliding contact surface allows large angle swing and slight angular compensation, well absorb assembly misalignment and equipment vibration impact. Inner and outer rings adopt integral quenched GCr15 bearing steel, precision spherical grinding process with uniform TXA self-lubricating composite coating, stable low-friction swing performance under heavy static and alternating shock load. Widely matched for large hydraulic cylinders, engineering machinery swing arms, mining lifting equipment, metallurgical hydraulic transmission assemblies and heavy agricultural equipment connecting joints.

2. Technical Specifications

Complete installation drawings, load characteristic curves and dust-water resistance accelerated durability test reports can be provided upon customer request.

3. Key Advantages

1. Double-sided 2LS integrated lip sealing design, fully isolate external mud, dust and splashing coolant, adapt to open construction and mining harsh working environments, greatly extend internal self-lubricating layer service life
2. Exclusive TXA composite self-lubricating sliding layer, low friction torque, no regular grease filling, reduce daily equipment maintenance workload and labor cost
3. Large spherical contact surface design, ultra-high static heavy load bearing capacity, stable swing operation under long-time alternating impact and unbalanced load
4. Built-in ±4° self-aligning compensation function, effectively offset shaft and housing assembly installation deviation, avoid bearing local stress concentration and premature abrasion failure
5. Thick-wall integral inner and outer ring structure, overall quenching heat treatment, high hardness and strong anti-impact performance, not easy to deform under heavy compression load
6. Full customizable service support: special high-temperature resistant seal, P5 high precision grade, OEM laser marking, surface anti-rust coating, neutral export wooden case packaging
7. Double lip contact seal tightly fit inner ring spherical surface, effectively lock internal solid lubricant, avoid lubrication failure caused by grease loss in long-time swing operation
8. Compact overall outline layout, large load capacity under limited installation space, ideal connecting joint bearing for large hydraulic cylinder and heavy swing mechanical arms
