SKF PTB series friction bushings are cylindrical components mounted between a shaft and a housing to reduce friction and wear. They work as self-lubricating or lubricated bushings, supporting radial loads in rotating or oscillating movements. They are used in industrial and automotive machinery and equipment where a compact, low-maintenance solution is required. MR Accesorios Industriales sells this line as part of its range of power transmission and support components.

The PTB series designation is interpreted as follows: PTB indicates the type of friction bushing; the first number after the hyphen corresponds to the inner diameter (d), the second to the outer diameter (D) and the third to the length (B), all in millimeters. The suffixes J and S refer to design features, such as the type of material and the design of the lubrication grooves or channels. This nomenclature makes it possible to quickly identify the main dimensions and select the right bushing for each application.

These bushings are used in a wide variety of industries in Argentina, such as automotive, metallurgical, food and agricultural. They are found in pumps, compressors, conveyor belts, machine tools, bottling equipment and lifting systems. Their function is to support radial loads and allow relative movement between parts, reducing wear and noise. They are an economical and reliable alternative to bearings in low-speed, moderate-load applications, especially where space is limited.

To correctly select a PTB bushing, take into account the radial load, the sliding speed and the environmental conditions. Check that the inner diameter matches the shaft and the outer diameter matches the housing, respecting the recommended tolerances. Lubrication is key: some models incorporate channels that help distribute the lubricant. During assembly, ensure precise alignment to avoid uneven wear. If the bushing works in dirty environments, consider additional protection. Careful assembly extends the service life of the component.

As for equivalents and interchangeability, SKF PTB series friction bushings can be replaced by products from other manufacturers that follow the same dimensional designation (inner diameter, outer diameter and length). However, it is essential to verify the material, the type of lubrication and the tolerances, as they may vary between brands. If you have any doubts, consult our technical team to ensure compatibility.
