SKF PHG series timing belts with L pitch and S finish are used wherever two or more shafts have to stay in step. Teeth on the inside of the belt engage matching pulleys, so the drive runs without slip and the ratio stays fixed. Typical installations include machine tools, industrial printers, compressors and positioning systems. MR Industrial Accessories supplies this line and can help you work out the pitch and length you need.

Reading the code is the first step. PHG is the SKF timing belt family. The figure after it refers either to the tooth count or to the pitch length, depending on the series. The letter L sets the tooth profile, and the S plus a closing number, as seen in PHG 67-L-S800 or PHG 150-L-S1800, marks a construction or width variant. Comparing PHG 124-L-S1800 with PHG 158-L-S1800 shows how only the length changes while profile and finish stay the same. The series table is the reliable way to decode any given reference.

These belts suit drives that must repeat the same motion cycle after cycle. Packaging lines, industrial sewing machines, printing equipment, screw compressors, metering pumps and automation systems are common applications, as is food processing, where a dry drive with no oil is an advantage over chain. The L profile fits low and medium power drives running pulleys of the matching pitch, as long as alignment and tension follow the manufacturer's recommendations.

Choosing a belt means checking pitch, pitch length, width and tooth count. Pulleys must be aligned and tension set correctly, because an over-tight belt loads the bearings and a slack one can jump teeth. Unlike a V-belt, a timing belt does not stretch, so the center distance has to allow fitting without force. No lubrication is needed; instead, keep the drive clean and watch the teeth for wear. Guards or specific variants are worth considering where oil or dust is present.

Timing belts are specified by pitch and length, and equivalent profiles exist across brands. On a replacement, the safest route is the same code, or one that matches in pitch, length and width. A similar profile is not enough, since small differences in pitch or tooth count disturb synchronization. Where the exact code is not available, an alternative with the same critical dimensions can be reviewed. MR Industrial Accessories can compare options within its transmission range.
