The bearing housing of a jaw crusher is the core foundational component that supports the eccentric shaft and the moving jaw, while transmitting the crushing force. Since jaw crushers are subjected to extreme alternating vibrational loads and severe impact loads during operation, the design and manufacturing quality of the bearing housing directly determine the overall stability of the machine and the service life of the bearings.
1. Core Functions and Positioning
The primary function of the bearing housing is to secure and support the spherical roller bearings, safely transmitting the massive loads generated during the crushing process to the frame.
In a typical jaw crusher, there are usually two pairs (a total of four) bearing housings:
Frame Bearings: Installed on both sides of the frame to support the connection between the eccentric shaft and the frame.
Moving Jaw Bearings: Installed on both sides of the moving jaw body to support the connection between the eccentric shaft and the moving jaw.
2. Structural Classifications
Depending on equipment specifications and installation requirements, bearing housings are mainly divided into two structural types:
Integral Bearing Housings: These offer extremely high rigidity, with uniform wall thickness and no joint clearance, effectively resisting extreme impact loads. This structure is typically applied to the frame support of jaw crushers and the moving jaw of certain premium European-style jaw crushers (such as the PEW series). The drawback is that disassembly requires pulling out the shaft assembly, demanding more installation space.
Split Bearing Housings: Composed of two halves (top/bottom or left/right), their greatest advantage is that installation and maintenance can be performed without removing the drive shaft. This structure is widely used in large vibrating screens and long-distance feeders. However, under vibrating conditions, the machining precision of the flatness and parallelism of the mating surfaces is extremely critical; otherwise, it can easily lead to clearance issues and abnormal noise.
3. Materials and Manufacturing Processes
Frame Bearing Housings: To ensure sufficient strength and impact resistance, frame bearing housings are typically manufactured using an integral cast steel structure (such as high-strength steel castings).
Moving Jaw Bearing Housings: Moving jaw bearing housings are also predominantly cast. Some newer equipment utilizes high-strength steel castings to enhance radial strength and extend the service life of the bearings.

The mainframe is designed for continuous heavy-duty operation. Wear parts such as jaw plates, liners and blow bars are made of high-manganese steel or alloy materials, and their service life depends on the material hardness and working hours.
Every machine goes through material inspection, machining inspection, assembly and a full no-load test run before shipment. Inspection records and test videos are provided to customers.
Warmly welcome. You can visit our manufacturing base in person, and remote video inspection is also available for customers from overseas.
Yes. Package orders of a full line or multiple machines usually receive a more favorable price and priority in the production schedule.
Large mainframes are shipped by sea in containers or bulk vessels; smaller machines and spare parts go by container, air freight or international express, with full packaging for moisture and rust protection.
