A heavy-duty bearing factory in Wuxi, Jiangsu, demands high dimensional accuracy, internal structural uniformity, and delivery time for annular forgings when producing large slewing bearing bearings. The factory has long faced issues such as large forging processing allowances, low material utilization, and long subsequent turning times, with some suppliers struggling to meet the demand for fast delivery orders.

Case Summary

This client is a well-known domestic heavy-duty bearing manufacturer, whose bearings are mainly used in construction machinery, wind power equipment, and other fields. To enhance product competitiveness, customers urgently need a partner that can stably provide high-precision, low-margin ring forgings, in order to reduce manufacturing costs and shorten delivery cycles.

Customer pain points

Existing forging suppliers had the following issues: uneven wall thickness of forgings led to subsequent processing allowances generally exceeding 8mm, and material utilization rates were less than 70%; Poor consistency of internal metallographic structure affects deformation control after heat treatment of bearing rings; Single-batch capacity is limited, with delivery delays of about 15% during peak seasons.

Product advantages

Relying on the roller ring process and intelligent production lines, Jianing Forging provides customized solutions tailored to customer needs:

• By adopting fine ring technology, the wall thickness tolerance of forgings is controlled within ±1mm, with single-side machining allowance reduced to 3mm, increasing material utilization to over 85%;
• By optimizing forging temperature and deformation procedures, a fine grain uniform circular microstructure is obtained, reducing subsequent heat treatment deformation rates by about 30%;
• Equipped with dedicated tooling and scheduling systems, it achieves stable delivery of over 200 units per batch, with a on-time delivery rate exceeding 98% during peak seasons.

Batch validation has shown that this solution helps customers save about 12% on raw material costs annually, reduces machining hours, and improves overall production line efficiency.
