SKF PHC series roller chains with O/L finish are power transmission links used to connect toothed shafts and transfer motion and torque in industrial machinery. They are used in equipment requiring synchronism and fatigue resistance, such as conveyors, gearboxes and machine tools. MR Accesorios Industriales sells this line, with advice to choose the right pitch and number of strands.

The PHC designation identifies the SKF roller chain line. The number that follows indicates the pitch according to the ANSI standard: the higher the number, the larger the pitch. The suffix -1, -2 or -3 indicates whether the chain is single, double or triple strand. The O/L finish distinguishes the variant with lifetime-lubricated bushings and pins, designed for applications where frequent relubrication is not possible.

These chains are found in the food, cement, automotive and material handling industries. In Argentina they are commonly seen in clinker conveyors, bucket elevators, bakery machinery and packaging lines. They are also used in the main drive of mills, mixers and pumping equipment. Their roller and bushing construction allows them to absorb shock loads and operate at moderate speeds with a suitable transmission ratio.

To select a PHC O/L chain, take into account the power to be transmitted, the shaft speed and the number of teeth on the sprockets. Lifetime lubrication limits the application to specific temperature and speed ranges; if the environment is very dirty or humid, additional seals should be evaluated. Installation requires aligning the sprockets in the same plane and checking the correct tension: a chain that is too tight accelerates wear on bushings and rollers. Periodic cleaning and elongation checks are key to service life.

SKF PHC O/L roller chains are interchangeable with other brands that follow the ANSI standard in terms of pitch and roller width. When replacing, compare the pitch number and the number of strands; the designation PHC 35-2O/L, for example, is equivalent to a double-strand chain with pitch 35. Not all O/L finishes from different brands share the same internal lubrication, so it is recommended to verify dimensional compatibility before mixing links.

If you need to replace a chain or build a complete drive, send us the part number on the plate or on the old chain via WhatsApp. At MR Accesorios Industriales we help you confirm the pitch, the number of strands and the compatible sprockets. We can also advise you on installation and the right lubrication for your equipment.
