Standard Cast 50Mn Sprocket for Crawler Excavators and Bulldozers
A standard cast drive sprocket cast in 50Mn steel for crawler excavators, bulldozers and crawler loaders in the 5-80 ton class. The sprocket carries drive-wheel power into the track chain and keeps walking speed stable while limiting chain wear. This cast version is aimed at earthmoving, municipal works, landscaping and general construction fleets that need dependable replacement parts with mainstream model coverage.
Standard cast 50Mn sprocket with machined tooth profile
Key Features
50Mn cast body
Cast in 50Mn steel with a machined tooth profile, giving a consistent replacement part for standard-duty crawler fleets.
HRC48-56 tooth surface
Tooth surface hardness runs HRC48-56, so the drive face holds its shape and keeps chain engagement stable through the wear cycle.
Matched to mainstream models
Stocked across CAT, Komatsu, Hitachi, Sany, SDLG and Shantui machine families, which shortens the wait when a machine is down.
Wide climate range
Rated for -30°C to 60°C working temperature, covering cold-region winter sites and hot summer construction seasons.
Inspected before shipment
Produced under an ISO9001:2015 quality system with full-process inspection, and covered by a 12-month quality warranty.

Materials and Structure
50Mn is cast into the sprocket body and then machined on the tooth ring, so the tooth spacing and profile sit within the tolerances the track chain expects. The casting route keeps cost predictable for fleets replacing sprockets on a regular maintenance interval, while the machined teeth carry the drive load and keep meshing with the track link and bushing. Every piece is checked for dimensions, hardness and surface condition before packing.
Applications
EarthmovingMunicipal worksLandscapingRoad constructionFarm land levelingQuarry site
Suited to crawler excavators, bulldozers and crawler loaders on construction sites, municipal earthwork, land leveling and quarry hauling, including muddy ground and wide temperature swings from -30°C to 60°C.
Customization
ODM customization is available with free logo engraving, and models outside the standard stock list can be matched on request. Provide the machine brand, model and working condition so the tooth count and mounting dimensions can be confirmed.
FAQ
When should I choose the cast sprocket instead of a forged one?The cast sprocket is the standard-duty option for general earthmoving, municipal and landscaping fleets. For continuous mining and quarry impact duty, the quenched forged 40Mn2 sprocket is the heavier option.
Which material is used?The standard cast sprocket is cast in 50Mn steel, with tooth surface hardness of HRC48-56.
Which machine models can you match?Coverage includes CAT, Komatsu, Hitachi, Sany, XCMG, SDLG and Shantui crawler machines in the 5-80 ton range. Send your model to confirm the exact match.
What temperature range does it work in?The rated working temperature range is -30°C to 60°C.
How is quality controlled?Production runs under the ISO9001:2015 quality management system with full-process inspection from incoming material to finished product, and each order carries a 12-month quality warranty.
Can the sprocket be branded for our own company?Yes, ODM customization with free logo engraving is supported. Confirm the artwork and model before production is scheduled.
