\n

The 120HSP-00 is a heavy-duty roller chain designed to match Caterpillar OEM specifications. It is built for drive and conveyor applications in mining, construction, and manufacturing environments where standard ANSI or ISO chains are insufficient. The “HSP” designation indicates a reinforced high-strength plate series, offering higher fatigue resistance and tensile strength compared to standard ANSI No.120 chain.<\/p>\n

Chain plates are manufactured from 40Mn manganese steel and undergo a dedicated heat treatment process to achieve the required hardness profile. Pins are produced from 40CrNiMo or 42CrMo alloy steel, providing torsional resistance and resistance to bending fatigue under shock loading. Sleeves and rollers are made from 20Mn and medium-carbon steel respectively, with surface hardening applied to reduce wear at the pin-bushing and roller-sprocket interfaces.<\/p>\n

This chain is a direct-fit replacement for Caterpillar equipment using the 120HSP or equivalent chain specification. It is also used in OEM and aftermarket applications across excavators, crawler dozers, draglines, and other heavy tracked or chain-driven machinery.<\/p>\n<\/div>\n

Maintenance Guidelines<\/h2>\n\n\n\n\n\n\n\n
Sm\u00f6rjning<\/td>\nApply chain oil or grease to the pin-bushing interface at regular intervals. In high-temperature or contaminated environments, a sealed or O-ring variant may be more suitable. Dry running significantly reduces fatigue life.<\/td>\n<\/tr>\n
Elongation Check<\/td>\nMeasure chain pitch elongation at regular intervals using a chain wear gauge across a fixed number of links. Replace the chain when elongation exceeds 3% of nominal pitch length.<\/td>\n<\/tr>\n
Sprocket Inspection<\/td>\nReplace worn sprockets when fitting a new chain. Running a new chain on a worn sprocket causes accelerated and uneven wear, significantly shortening service life.<\/td>\n<\/tr>\n
Inriktning<\/td>\nConfirm drive and driven sprockets are correctly aligned before installation. Misalignment places lateral loads on chain plates, increasing risk of plate cracking and premature failure.<\/td>\n<\/tr>\n
Replacement Cycle<\/td>\nFollow the equipment manufacturer’s recommended replacement interval. In severe-duty environments, inspect more frequently and replace based on measured wear rather than calendar intervals alone.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Compatible Sprockets<\/h2>\n
\u2699<\/span>
\nThe 120HSP-00 operates with sprockets designed for ANSI No.120 pitch (38.10 mm). We supply matching sprockets in a range of tooth counts and bore sizes. Specifying the sprocket alongside the chain ensures correct tooth profile engagement and maximises the working life of both components.<\/div>\n

Vanliga fr\u00e5gor<\/h2>\n
\n
Q<\/span>
\nWhat is the tensile strength of the 120HSP-00 chain?<\/strong><\/div>\n

The minimum tensile strength is 340 kN (approximately 76,400 lbf). This exceeds the standard ANSI No.120 requirement, reflecting the reinforced plate and pin materials used in the HSP series.<\/p>\n<\/div>\n

\n
Q<\/span>
\nWhat is the pitch of the 120HSP-00?<\/strong><\/div>\n

The pitch is 38.10 mm, corresponding to ANSI chain number 120 (1-1\/2 inch pitch). This matches the standard sprocket pitch for No.120 chain and is compatible with Caterpillar equipment using this chain specification.<\/p>\n<\/div>\n

\n
Q<\/span>
\nHow does the 120HSP differ from standard ANSI No.120 chain?<\/strong><\/div>\n

The HSP designation indicates a high-strength plate series. Compared to standard No.120 chain, the 120HSP-00 uses heavier side plates (40Mn steel), higher-grade alloy steel pins (40CrNiMo or 42CrMo), and is manufactured to tighter tolerances to achieve a higher fatigue life and tensile strength rating.<\/p>\n<\/div>\n

\n
Q<\/span>
\nWhat industries is this chain suitable for?<\/strong><\/div>\n

The 120HSP-00 is used in mining (conveyors, feeders, haulage), construction (Caterpillar-compatible equipment), and heavy industrial manufacturing (press transfer lines, mill drives). It is not recommended for light-duty or food-grade applications.<\/p>\n<\/div>\n

\n
Q<\/span>
\nHow do I maintain this chain correctly?<\/strong><\/div>\n

Lubricate the pin-bushing interface regularly, monitor elongation using a wear gauge, inspect and replace sprockets when fitting a new chain, and confirm shaft alignment before installation. Replace the chain when elongation exceeds 3% of nominal pitch length.<\/p>\n<\/div>\n
