Quick Summary
Tenfaye manufactures custom cast steel rolling mill chocks and bearing housings in China. Produced to customer drawings and specifications, each component can include heat treatment, precision machining and quality inspection to meet rolling mill application requirements.
Rolling mill chocks support the work rolls and backup rolls in rolling mill stands. They house the roll bearings and help maintain roll position under heavy loads during metal rolling. Their dimensional accuracy, structural integrity and machining quality directly affect mill operation and maintenance.
For steel mills and equipment manufacturers looking for a reliable rolling mill chock supplier in China, key considerations include casting quality, machining accuracy, material properties and the ability to manufacture components to precise drawings.
Tenfaye manufactures custom cast steel rolling mill chocks, bearing chocks and heavy-duty bearing housings for industrial applications.
Rolling mill chocks are used in various rolling mill configurations. Their dimensions, bearing arrangements and structural requirements depend on the mill design, roll size and operating conditions.
Hot Rolling Mills
Hot rolling mills operate under heavy rolling forces and repeated mechanical loads. Chocks must support the roll bearings and maintain the required alignment throughout operation.
Cold Rolling Mills
Cold rolling mills require accurate roll positioning to maintain strip thickness and product quality. Bearing seat dimensions, machining tolerances and component fit are critical when manufacturing replacement chocks.
Rolling Mills for Non-Ferrous Metals
Chocks are also used in rolling mills processing aluminum, copper and other non-ferrous metals. Each application has specific dimensional and operating requirements, so the casting and machining processes should be based on the equipment design.
Rolling mill chocks are often large, heavy components with complex geometries and precisely machined bearing seats. Material selection and manufacturing process control are essential to achieving the required mechanical properties and dimensional accuracy.
Tenfaye produces cast steel chocks according to customer drawings and technical specifications. The manufacturing process can include the following stages.
Steel Melting and Refining
Steel melting and refining processes are used to control chemical composition and molten steel quality, helping reduce the risk of inclusions and other material defects.
Casting Process Control
The casting process is designed according to component geometry, wall thickness and solidification requirements. Proper process planning helps reduce the risk of shrinkage defects and supports internal soundness.
Heat Treatment
Heat treatment is selected according to the material grade, casting design and specified mechanical properties. The process follows the applicable technical requirements for the component.
Rough and Finish Machining
Machining covers bearing seats, mounting surfaces and other specified features according to customer drawings. Machining allowances and dimensional tolerances are considered during production planning.
Quality Inspection
Inspection requirements are established according to the customer's specifications and agreed acceptance criteria. Dimensional checks and non-destructive testing can be included as required.
For large steel castings, shrinkage control, internal soundness and dimensional stability are particularly important. Addressing these factors during production planning helps reduce manufacturing risks and supports consistent product quality.

The bearing seat is one of the most critical functional areas of a rolling mill chock. Its dimensions, geometry and surface finish must meet the tolerances specified in the drawings. Incorrect dimensions or poor alignment can affect bearing installation and roll positioning.
Depending on the project requirements, quality inspection may include:
Dimensional inspection of bearing seats and mounting surfaces
Verification of key dimensions and geometric tolerances
Ultrasonic testing (UT) and magnetic particle testing (MT), where specified
Chemical composition analysis and mechanical property testing
Material and inspection documentation as agreed with the customer
For replacement chocks, confirming the inspection scope and dimensional requirements before production is particularly important. Original drawings, material specifications and verified measurements help reduce fit-up risks during installation.
Price is only one factor when sourcing heavy steel castings. Buyers should also assess the supplier's casting capacity, machining capabilities, quality control procedures and experience with heavy industrial components.
Before placing an order, consider the following points.
Drawing and Specification Review
The supplier should work from verified drawings, material grades, dimensional tolerances and inspection requirements.
Casting and Machining Capability
Confirm that the manufacturer can handle the required casting dimensions and weight, as well as the specified machining operations.
Quality Documentation
Agree on inspection methods, acceptance criteria and the required material test reports before production begins.
Replacement Part Compatibility
For existing rolling mills, provide original drawings or verified field measurements to help ensure that replacement chocks meet the required installation dimensions.
A clear understanding of these requirements helps buyers evaluate suppliers and reduce avoidable problems during manufacturing and installation.
