The 980811NT Forklift Mast Roller Bearing is a specialized, high-capacity bearing engineered to manage the intense radial loads generated by heavy lifting equipment. Measuring 55 mm (ID) × 119.2 mm (OD) × 34 mm (Width) and forged from premium Chrome Steel, it fixes and reduces the friction coefficient of load-bearing components along the forklift's mast. Equipped with heavy-duty rubber seals (2RS) to protect against industrial dust and debris, this bearing significantly extends the service life and operational smoothness of 5-10 ton forklifts. We offer OEM/ODM services, competitive wholesale pricing, and reliable global fulfillment.
Forklift bearings are an irreplaceable hardware component within material handling equipment. Unlike standard plain bearings or deep groove ball bearings, the 980811NT Mast Bearing is designed with extraordinarily thick outer rings to roll directly inside the steel channels of the forklift's upright mast. Its primary function is to guide the lifting carriage smoothly, drastically reducing the friction coefficient of the load components while safely supporting massive radial and axial forces.
Ensure exact fitment for your fleet or aftermarket rebuild kits by verifying the dimensions below:
Item | Specification |
|---|---|
Model Number | 980811NT |
Inner Diameter (d) | 55 mm |
Outer Diameter (D) | 119.2 mm |
Width / Thickness (B/C) | 34 mm |
Material | Premium Chrome Steel (GCr15) |
Seal Type | 2RS (Double-sided heavy-duty rubber seals) |
Weight | ≈ 0.8 kg - 1.50 kg |
Clearance | Available in specific radial and axial clearance classifications |
(Note: The standard 980811 model typically measures 55x118.7x25mm. The "NT" suffix indicates a specialized, wider, and thicker outer profile [119.2x34mm] for specific heavy-duty mast channels.)
The 980811NT is designed to survive the unforgiving conditions of industrial warehouses, ports, and construction sites:
High Radial Load Capacity: The thick-walled outer ring prevents deformation under the extreme pressure of lifting 5 to 10-ton loads, ensuring the mast operates without binding.
Superior Sealing (2RS): The heavy-duty rubber seals prevent the ingress of abrasive dust, dirt, and moisture, keeping the internal grease clean and drastically reducing maintenance and replacement frequency.
Long-Life Chrome Steel: Forged from GCr15 steel for maximum wear resistance, reducing long-term fleet maintenance costs.
This specific mast bearing is widely utilized across the heavy material handling sector:
5 to 10-ton capacity industrial forklift trucks (e.g., Heli, Lonking, and other major brands).
Reach trucks, stackers, and automated guided vehicles (AGVs).
Heavy agricultural machinery, mining equipment, and port logistics.
We provide highly reliable supply chains for heavy machinery builders and forklift repair networks globally.
Quality Standard: Manufactured under strict ISO9001:2008 / ISO9001:2000 quality management systems.
Customization: We offer OEM and ODM services, including custom cage materials (steel, brass, or nylon) and specific clearance adjustments based on your engineering requirements.
Packaging & Delivery: Supplied in secure, standard industrial carton boxes to prevent transit damage. Contact our sales team for exact lead times based on your requested quantity.
