The cylindrical roller bearing features line contact between the rolling element and raceway, allowing it to bear heavy radial loads. These bearings are ideal for applications involving heavy or shock loads and high-speed rotation. They are separable, making them easy to mount and dismount. While most single-row bearings handle only radial loads, those with ribs on both inner and outer rings can also support light axial loads.

**About Us**
HENGLI Machinery Company is a well-established Chinese bearing supplier, specializing in the design, manufacture, and wholesale of bearings. We have been producing spherical and cylindrical roller bearings since 1970, and our company is certified by the Chinese Ministry of Machine Building. We operate two additional specialized bearing factories, enabling us to provide top-quality products such as needle roller bearings, spherical plain bearings, rod ends, ball joints, tapered roller bearings, wheel hub bearings, and non-standard bearings.
**FAQ**
Q1 - What are your advantages?
A - As a manufacturer, we focus on quality and precision. Your choice determines the outcome.
Q2 - What types of bearings do you offer?
A - Spherical Roller Bearings, Cylindrical Roller Bearings, Needle Roller Bearings, Cam Followers, Thrust Bearings, Spherical Plain Bearings, Rod Ends, Ball Joints, Wheel Hub Bearings, Tapered Roller Bearings.
Q3 - What is your production process?
A - Heat Treatment → Grinding → Parts Inspection → Assembly → Final Inspection → Packing.
Q4 - How can I customize a bearing (non-standard)?
A - We offer OEM and customized (non-standard) services. Please provide drawings and detailed technical specifications.
Q5 - What should I consider before installation?
A - New bearings are usually coated with preservative; no need to remove it unless incompatible. Keep the bearing clean and install in a dry, dust-free environment.
Q6 - How should I store and maintain bearings properly?
A - Avoid storing on concrete floors. Use pallets or shelves in a dry, temperature-controlled area. Place oil paper or plastic sheets between parts for tapered roller bearings.
The PE Pipe Production Line can be categorized based on the pipe diameter and application.
1. PE Water Supply Pipe Production Line
This production line can produce pipes with a diameter range of 16mm to 1200mm. For example, the XDC-HDPE63 model can produce pipes with a diameter of 16-63mm, with a maximum output of 200 kg/h.
It is designed for high-speed production and features a stable and simple operation. The pipes produced have smooth inner walls, extremely low friction coefficients, good flexibility, high impact strength, and corrosion resistance.
Widely used in municipal water supply systems, building water supply systems, and industrial water treatment systems.
2. PE Gas Pipe Production Line
Similar to the water supply pipe production line, it can produce pipes with a diameter range of 16mm to 1200mm. The XDC-HDPE160 model, for instance, can produce pipes with a diameter of 63-160mm, with a maximum output of 300 kg/h.
The production line is equipped with advanced extruders and precision die heads to ensure the quality of the pipes. The pipes have good flexibility, high impact strength, and corrosion resistance.
