Product Description
Is your rolling mill suffering from frequent, unplanned downtime due to premature roll neck bearing failure? The root cause may not be the bearing itself, but the component holding it: the bearing chock.
Worn, damaged, or poorly manufactured bearing chocks are a leading cause of catastrophic bearing damage, costing operations hundreds of thousands of dollars in replacement parts and lost production. Yile Machinery manufactures high-precision, robust bearing chocks that are engineered to solve this problem, protecting your investment and maximizing mill availability.
A bearing chock is more than just a block of steel. When it fails to meet critical specifications, it directly leads to:
Misalignment and Uneven Loading: If the bearing bore is worn or machined incorrectly, it forces the bearing to run misaligned. This concentrates immense force onto just a few rollers, causing rapid wear and spalling.
Fretting Corrosion: A loose fit between the bearing's outer race and the chock bore allows for micro-movements, creating oxidation (fretting) that damages both surfaces and compromises the integrity of the fit.
Loss of Rigidity: Cracks or excessive flexing in the chock body under load can alter the roll gap, leading to inconsistencies in product thickness and quality issues.
These issues result in a cycle of expensive maintenance, frequent bearing replacements, and unpredictable downtime.
Our bearing chocks are designed as a direct solution to these common failure modes. We address the root cause by focusing on two key areas:
Uncompromising Material Strength:
We use high-quality cast steel (e.g., ZG35CrMo) or ductile iron, which provides superior strength and rigidity to withstand the highest rolling forces without deflection.
Every casting is heat-treated to optimize its mechanical properties and relieve internal stresses, guaranteeing stability and long-term performance.
Sub-Millimeter Machining Accuracy:
The bearing bore is the heart of the chock. Using state-of-the-art CNC boring mills, we machine this critical surface to extremely tight tolerances, ensuring a perfect press or sliding fit as required by the bearing manufacturer.
This precision guarantees the load is distributed evenly across all bearing rollers, dramatically increasing bearing service life and preventing premature failure.
Investing in a precision-machined bearing chock from Yile Machinery provides a clear and rapid return:
Drastically Reduced Bearing Consumption: Maximize the life of your expensive roll neck bearings.
Increased Mill Uptime: Eliminate unplanned downtime caused by chock-related bearing failures.
Consistent Product Quality: Maintain a stable and precise roll gap for improved gauge control.
Lower Maintenance Costs: Reduce the labor and resources spent on frequent roll changes.
