The SKF PTB 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 solution with simple maintenance is required. MR Accesorios Industriales sells this line as part of its range of 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 inside diameter (d), the second to the outside diameter (D) and the third to the length (B), all in millimeters. The suffixes J and S refer to design characteristics, such as the material type and the design of lubrication grooves or channels. For example, PTB-12X22X8-J1S has a 12 mm inside diameter, 22 mm outside diameter and 8 mm length. 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, metalworking, 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, sliding speed and environmental conditions. Check that the inside diameter matches the shaft and the outside diameter matches the housing, respecting the recommended tolerances. Lubrication is key: some models incorporate channels that facilitate lubricant distribution. During installation, ensure precise alignment to avoid irregular wear. If the bushing works in dirty environments, consider additional protections. Careful installation extends the service life of the component.

Regarding equivalents and interchangeability, SKF PTB series friction bushings can be replaced by products from other manufacturers that follow the same dimensional designation (inside diameter, outside diameter and length). However, it is essential to verify the material, lubrication type and tolerances, as they can vary between brands. Do not invent codes: always compare technical specifications. If you have doubts, consult our technical team to ensure compatibility.
