Welcome to Linqing Xinshengdi Bearing Co., Ltd.
780709H Heavy-Duty Forklift Mast Bearing
- Massive Structural Integrity: The uniquely thick outer ring easily absorbs punishing impacts and resists deformation.
- Smooth Hydraulic Operation: Low-friction rotation allows the lifting cylinders to operate smoothly without energy-wasting binding.
- Extended Operational Life: Premium steel and advanced heat treatment create a highly wear-resistant interface against steel mast rails.
- Rigorous QA Validation: Every batch is tested for dynamic load capacity and seal efficacy before leaving our facility.

Product Introduction
The 780709H is a formidable forklift mast bearing, engineered to deliver exceptional structural support and unyielding reliability. Measuring 45 x 123 x 40 mm, this bearing is characterized by an extremely favorable ratio of outer diameter to inner bore, resulting in a massively thick outer ring designed to conquer extreme radial loads. Produced in our high-end manufacturing division, the 780709H undergoes stringent quality protocols, including advanced ultrasonic testing to ensure zero subsurface metallurgical defects. The precision-ground rolling surface ensures flawless mast rail tracking, significantly reducing hydraulic strain on the forklift. We provide our international wholesale partners with an enterprise-grade component that guarantees maximum uptime in intense, heavy-duty logistics operations.
Applications
Heavy-duty warehouse forklifts and rough-terrain lift trucks.
Industrial mast assemblies and heavy carriage guides.
Specialized heavy-lift attachments (e.g., paper roll clamps, carton clamps).

FAQ
Q: Can this bearing be used on attachments rather than the main mast?
A: Yes, its high radial load capacity makes it an excellent choice for the carriage rollers on heavy hydraulic forklift attachments.
Q: Is the outer ring flat or crowned?
A: Please specify your OEM requirement upon ordering. We can supply this bearing with a perfectly flat outer profile or a slight micro-crown to prevent edge loading in the mast channel.
OEM & Custom Service
Our advanced manufacturing hub offers tailored B2B solutions, including custom-formulated extreme-temperature greases (for cold storage warehouse applications) and specialized rust-resistant coatings for the outer ring.
Packing & Delivery
To prevent transit damage to these heavy components, they are individually shielded in heavy VCI plastic, nested in impact-absorbing foam, and securely packed into custom-built, heat-treated wooden export crates.
