HSN's Introduction To Dump Truck Bearings

I. Major Dump Truck Brands

Dump trucks are widely used in mining, quarrying, and heavy civil engineering projects worldwide by leading global manufacturers of construction and mining machinery. Representative brands include Caterpillar (CAT), Komatsu (Japan), Liebherr (Germany), and Belaz (Belarus).

II. Best-Selling Models

These models are typically proven in the market, dominating their specific tonnage segments and widely recognized by mining customers. Specifically, they include the following four models:

  1. Caterpillar 797F: With a payload capacity of 363 tons, this is a benchmark in mechanical transmission. The latest F-model, with its exceptional reliability and productivity, has become the preferred choice for ultra-large mines.
  2. Komatsu 980E-5: With a payload capacity of 400 tons, this electric transmission flagship inherits the high reliability of the 930E and utilizes advanced electric drive and automation technologies for outstanding fuel efficiency. It also supports an unmanned driving option and is the world’s best-selling ultra-large tonnage mining truck.
  3. Liebherr T 284: With a payload capacity of 363 tons, this truck is equipped with a proprietary electric drive system and competes in the market with high performance, low fuel consumption, and an excellent driving experience.
  4. BelAZ 75710: With a payload capacity of 450 tons, it is the world’s largest mining truck. However, it serves more as a symbol of technology and a national brand, with relatively low actual sales, primarily in the Commonwealth of Independent States (CIS)

III. Main Sales Regions

The market for dump trucks is closely tied to the distribution of large open-pit mines. It can be said that wherever there are large open-pit mines, there is demand for dump trucks. Key sales regions include:

1. Asia-Pacific - the world's largest and most active market: China, Australia, India, Indonesia, Mongolia, etc.

2. The Americas: The United States, Canada, Chile, Peru, Brazil, etc.

3. Commonwealth of Independent States (CIS) - the traditional sphere of influence of BelAZ: Russia, Kazakhstan, Ukraine, etc.

4. Africa: South Africa, Botswana, Zambia, Namibia, Guinea, etc.

5. The Middle East.

IV. Dump Truck Bearing Types

Dump trucks operate under extremely heavy loads and harsh conditions, and the bearings used in these vehicles are directly related to equipment reliability, uptime, and lifecycle costs. The core features of these bearings include oversized dimensions, ultra-high load capacity, high reliability, and excellent sealing. Specific application locations and types are as follows:

  1. Wheel hub bearings: Oversized double-row tapered roller bearings or matched tapered roller bearing units.
  2. Gearbox bearings: Cylindrical roller bearings, tapered roller bearings, deep groove ball bearings.
  3. Engine bearings: Deep groove ball bearings, cylindrical roller bearings, and camshaft bearings.
  4. Steering system bearings: Large thrust roller bearings or tapered roller thrust bearings.
  5. Lifting system bearings (hydraulic tilting systems): Large spherical plain bearings or self-lubricating bearings.

V. HSN's Bearing Supply Capabilities

It’s worth noting that HSN stocks a wide range of bearings, including the oversized double-row tapered roller bearings and large thrust roller bearings mentioned above. Images of the bearings are included for reference.

Regarding the specific bearing parameters used in dump trucks, most related companies maintain confidentiality, making it difficult to obtain valuable information. The aftermarket is primarily dominated by original equipment suppliers, such as NTN from Japan and Timken from the United States. Both of these bearing manufacturers employ specialized numbering systems for dump truck bearings. Despite this, HSN Company can still design drawings based on field measurement data provided by maintenance companies and combine this with technical information from bearings used in the same positions of other known vehicle brands to customize bearing production. If you have any requirements for customized bearings for dump trucks, please contact our sales department. We would be delighted to discuss technical details with you and can dispatch a technical team to conduct on-site measurements to design the best solution for you.
