Our OEM replacement parts are widely used in hydraulic systems, industrial machinery, automation equipment, engineering equipment, and customized mechanical applications.
What Are OEM Replacement Parts?
OEM Replacement Parts are components manufactured according to original equipment specifications or customer-defined requirements to replace existing machine parts.
In industrial applications, equipment downtime can result in significant production losses. When original components are unavailable, outdated, or require improvement, customized OEM replacement parts provide an effective solution.
At Tianjin Keypower Hydraulic Company Limited, we manufacture replacement components witha focus on:
- Accurate dimensional matching
- Reliable mechanical performance
- Material compatibility
- Long service life
- Stable production quality
Our OEM manufacturing service enables customers to maintain equipment performance while reducing procurement complexity and improving supply chain flexibility.

Custom Parts Manufacturing From Drawing
Turning Customer Designs Into Finished Components
One of our key advantages is the ability to manufacture parts directly from customer drawings.
Our technical team reviews every project carefully before production, including:
- Product structure
- Material requirements
- Tolerance specifications
- Surface treatment requirements
- Assembly conditions
- Operating environment
Based on this information, we develop a suitable manufacturing solution.
Customers can provide:
- 2D CAD drawings
- 3D CAD models
- Existing part samples
- Product photos with dimensions
- Equipment specifications
Our engineers then convert customer requirements into accurate production instructions.
This drawing-based manufacturing approach allows customers to develop customized replacement parts without investing in additional tooling or production facilities.
