Overview: The document provides technical details about TEX-MET®, a registered trademark of GLT-GleitLagerTechnik® GmbH, focusing on their wrapped composite sliding bearings with PTFE fibres fabric overlay, which are maintenance-free.
Specifications: TEX-MET® bearings are dry sliding bearings compliant with DIN 1494 / ISO 3547 standards. They are available in cylindrical bushings, thrust washers, and strips, with special designs produced on request. The bearings are made from carbon steel, stainless steel, and bronze, with a PTFE fibres fabric overlay.
Material Properties: The bearings exhibit excellent sliding and wear behavior, especially in rotating and oscillating movements, with good shock absorption and high load capacity. They do not absorb water.
Tolerance Details: Housing diameter tolerance is H7, bushing-inner diameter after mounting is H9, and shaft tolerance ranges from f7 to h8.
Performance Parameters: The specific load capacity is ≤ 350 N/mm² static and ≤ 180 N/mm² dynamic. The sliding speed is < 0.5 m/s, with a friction value between 0.03 to 0.20 µ. The temperature range is -50 to +250°C, and the maximum Pv value is 1.8 N/mm²*m/s, with short-term peaks up to 3.6.
Mounting Advice: It is recommended to use an adequate force fitting mandrel for installation. The shaft material should be steel, hardened or untempered, with a surface roughness of less than Rz 4.
Maintenance: TEX-MET® bearings are maintenance-free due to the PTFE fibres fabric overlay, and lubrication is not necessary or allowed.
Product Range: The document lists various sizes of cylindrical bushings (TXZ series) with measurements in millimeters, also available in inch sizes.
