The cylindrical roller bearing has line contact with the raceway, allowing it to bear heavy radial loads. These bearings are ideal for applications involving heavy or shock loads, as well as high-speed rotation. They are separable, making them easy to install and remove. Single-row cylindrical roller bearings are the most commonly used type. While they primarily handle radial loads, single-row bearings with ribs on both inner and outer rings can also carry light axial loads.

**About Us**
HENGLI Machinery Company is a well-established Chinese bearing supplier. We design, manufacture, and wholesale bearings. Our specialized manufacturer of Spherical Roller Bearings and Cylindrical Roller Bearings was established in 1970 and is accredited by the Chinese Ministry of Machine Building.
We have invested in two additional specialized bearing factories, which allow us to provide our clients with top-of-the-line products such as Needle Roller Bearings, Spherical Plain Bearings, Rod Ends Bearings, Ball Joint Bearings, Tapered Roller Bearings, Wheel Hub Bearings, and Non-Standard Bearings.
**FAQ**
Q1 – What are our advantages?
A – Manufacturer – Only the best. Your choice makes a difference.
Q2 – What are our products?
A – Spherical Roller Bearing, Cylindrical Roller Bearing, Needle Roller Bearing, Cam Followers, Thrust Bearing, Spherical Plain Bearing, Rod End, Ball Joint, Wheel Hub, Tapered Roller Bearing.
Q3 – What is the production process?
A – Heat Treatment – Grinding – Parts Inspection – Assembly – Final Inspection – Packing.
Q4 – How can we customize bearings (non-standard) from your company?
A – We offer OEM and customized (non-standard) services. You need to provide drawings and detailed technical data.
Q5 – What should I be careful about before installation?
A – Normally, the preservative on new bearings does not need to be removed. It is only necessary to wipe off the outside cylindrical surface and bore. If the grease is not compatible, wash and dry the bearing carefully. Bearings should be installed in a dry, dust-free room away from machines that produce swarf and dust.
Q6 – How should I store and maintain my bearings correctly?
A – Do not store bearings directly on concrete floors where water can condense. Store them on a pallet or shelf in an area with low humidity and no extreme temperature changes. Always place oiled paper or plastic sheets between rollers and cup races of 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.
Used for gas transportation piping systems in various industries.
3. PE Communication Pipe Production Line
This production line is designed to produce pipes with a diameter range of 16mm to 1200mm. The WR-630 model can produce pipes with a diameter of 250-630mm, with a maximum output of 1100-1200 kg/h.
It features a high degree of automation and optimized screw structure, ensuring stable production efficiency. The pipes produced have excellent corrosion resistance, compression resistance, and impact resistance.
Suitable for power communication systems.
4. PE Silicone Core Pipe Production Line
This production line can produce pipes with a diameter range of 16mm to 1200mm. The pipes have a silicone solid lubricant on the inner wall.
The silicone core pipe is widely used in optical cable communication network systems for railways and highways. It has the advantages of being moisture-proof, insect-proof, anti-corrosion, and anti-aging.
Used in optical cable communication network systems.
