American 900 series track rollers, also referred to as lower rollers or bottom rollers, are heavy-duty undercarriage components for American crawler cranes, designed to support the machine’s weight and guide the track chain. They are typically made from hardened cast or forged alloy steel to withstand harsh operating conditions.
Product Details and Specifications
These track rollers are specifically designed for models such as the American 9260, 9299, 9310A, and 9320 crawler cranes.
- Material: Common materials include high-quality alloy steels like 42CrMo, 40Mn2, 50Mn, and 35SiMn.
- Technology: The parts are manufactured using either forging or casting processes, followed by a whole quenching and tempering, and then surface hardening heat treatment.
- Design: The rollers are designed with large, hardened cast steel components mounted on heavy bronze bushings, with axles drilled for pressure grease lubrication. This design prevents the track shoes from buckling between the rollers.
- Quantity: The number of lower track rollers (per side frame) varies by specific crane model, e.g., Model 9299 has 12, and Model 9320 has 17.
- Warranty: They often offer a warranty of around 2500 working hours or one year.
