SKF PHC O/L roller chains are used to link toothed shafts and transmit motion and torque in industrial equipment. They suit drives that need synchronism and resistance to fatigue, including conveyors, gearboxes and machine tools. MR Industrial Accessories LLC supplies this line and can help you select the correct pitch and strand count.
The PHC code designates the SKF roller chain family. The number after PHC gives the ANSI pitch: larger numbers mean larger pitches. A suffix of -1, -2 or -3 tells you whether the chain is single, double or triple strand. The O/L version has bushings and pins lubricated for life, so it fits drives where frequent relubrication is not practical.
You will find these chains in food processing, cement, automotive and material handling operations. Typical uses include clinker conveyors, bucket elevators, bakery equipment and packaging lines, as well as the main drive of mills, mixers and pumps. The roller-and-bushing design helps them handle shock loads and run at moderate speeds with a suitable transmission ratio.
When choosing a PHC O/L chain, consider the power to transmit, the shaft speed and the number of sprocket teeth. Lifetime lubrication restricts the chain to certain temperature and speed ranges; in very dirty or humid conditions, look at additional sealing options. During installation, align the sprockets in the same plane and set the correct tension—too tight a chain speeds up wear on bushings and rollers. Regular cleaning and elongation checks help extend service life.
SKF PHC O/L chains interchange with other brands that follow the ANSI standard for pitch and roller width. For replacement, compare the pitch number and the number of strands; for instance, PHC 35-2O/L is a double-strand chain with pitch 35. Internal lubrication can differ between O/L finishes from different makers, so check dimensional compatibility before mixing links.
To replace a chain or build a complete drive, send the part number from the plate or the old chain via WhatsApp or email. At MR Industrial Accessories LLC, we help you confirm the pitch, strand count and compatible sprockets, and we can advise on installation and the right lubrication for your equipment.

Frequently asked questions
- What does the O/L finish mean on SKF PHC chains?
- O/L indicates lifetime lubrication on bushings and pins. This lowers maintenance where frequent relubrication is not possible, but temperature and speed limits still apply.
- How do I choose between a single, double or triple strand chain?
- The number of strands depends on the power to transmit and the space available. At the same pitch, a double-strand chain carries more load than a single-strand one, but needs wider sprockets. Always check the capacity of the existing sprockets.
- Are PHC O/L chains compatible with sprockets from other brands?
- Yes, provided the sprockets follow the ANSI standard for the same pitch and number of strands. Before mixing components from different brands, verify the roller diameter and the inner width of the link.
