C-type/Bow-type Bearing Press Machine

The bow-type/C-type bearing press machine is a compact, open-type press with an open operating space. Its body shape resembles the letter "C" or a bow, hence its name. It is ideal for pressing and disassembling interference-fit parts such as bearings, bushings, and gears. Below is a sharing from Jianlong Hydraulic Technology for your reference!

1. Core Structure: Open Body Design

• C-type Single-Arm Body: Constructed from high-quality steel plates by welding or integral casting, forming a three-sided open working space, facilitating operation, observation, and feeding from the side and front.

• Core Power: Typically hydraulically driven (cylinder located on the upper part of the machine body), but pneumatic-hydraulic booster or servo electric drive are also possible.

• Control Core: Integrated PLC and touch screen for precise control.

2. Typical Parameter Range

• Nominal Pressure: 1 ton to 100 tons (commonly 5T, 10T, 20T, 30T). • Throat depth (opening size): 100mm to 800mm, determining the depth to which the workpiece can be inserted.

• Working stroke: 50mm to 300mm.

• Control accuracy: Pressure accuracy up to ±0.5%, displacement accuracy up to ±0.01mm.

3. Performance Advantages

• Structural advantages: Three-sided open design, extremely convenient operation, easy integration into automated production lines.

• Precision advantages: Employs dual force and displacement monitoring to ensure press-fit quality and achieve zero-defect production.

• Versatile functions: In addition to press-fitting, it often includes functions such as flattening, straightening, riveting, and punching.

• Safe and reliable: Equipped with two-hand operation buttons, light curtain, anti-cylinder-fall safety devices, etc.

4. Core Application Areas

• Automotive manufacturing: Press-fitting of wheel hub bearings, gearbox bearings, connecting rod bushings, valve seats, etc.

• Motor industry: Press-fitting of end cover bearings, rotor shafts.

• Home Appliances & Hardware: Press-fitting of fan motor bearings, gears, and pins.

• Mechanical Equipment Repair: Disassembly and replacement of bearings and gears.

5. Key Selection Considerations

• Tonnage and Throat Depth: Determine the nominal pressure and throat depth based on the maximum pressure required for press-fitting and the workpiece size.

• Precision and Monitoring: For processes with high quality requirements, be sure to select a model with force-displacement monitoring and curve analysis functions.

• Power Type: Select hydraulic, pneumatic-hydraulic booster, or servo-electric power based on requirements for speed, cleanliness, and control precision.

• Safety and Integration: Confirm the safety protection level and consider compatibility with the automation interface of existing production lines.
