HT250 cast iron inlay bearing is a new product with HT250 as the substrate embedded with solid lubricant, which is a typical material-saving product. If there is pressure <14.5N/m㎡ or mechanical performance requirements are not very high occasions, can replace high force brass inlaid graphite bushings, can greatly reduce costs and meet the use of requirements. For example, a mold guide column, injection molding machine mold frame, and other fields can be completely used.

• Speed limit: 0.5m/s
• Dynamic load limit: 60/mm2
• Basic hardness: HB 80-230
• Temperature limit: 400℃
• PV limit:0.8N/mm2
• Friction coefficient : <0.18

HT 250 material is made of cast iron-based metal with special lubricants embedded.
The base metal withstands high load and the solid lubricants provide for self-lubrication.
The oilless steel bushing shows excellent performance without pre-lubrication under conditions of extremely high or lower temperature with lower speed.

It can be used for pump casings, containers, towers, flanges, stuffing box bodies and glands, carbonization towers, nitrification towers, etc. that require high strength and certain corrosion resistance; Case hardened parts.
Because of its small thermal deformation, it is often used in high-temperature occasions.

Steel plate casting bearing is a solid lubrication product with solid, lubricant embedded after the centrifugal casting of the copper layer in the base body of a steel sleeve, which can save cost and also improve the compressive strength. Its end face can be welded to the substrate for use, so it is suitable for metallurgical machinery, construction machinery, oil transfer machinery, etc., where oil cannot be added.

Speed limit: 0.5m/s
Dynamic load limit: 70/mm2
Basic hardness: HB 60~90
Temperature limit: 300℃
PV limit:1.6N/mm2
Friction coefficient : <0.16

The Oilless bearings give higher life in comparison with conventional bearing. Hydrostatically lubricated bearings are lubricated by an outside pump that maintains a static quantity of pressure. Rotary bearings might include swinging and rotation in 1 direction. Plain bearings, generally, are the least expensive sort of bearing. They are manufactured with different constructions and product selection depends on the operating conditions of the application and performance requirements. Different types of linear plain bearings Linear plain bearings are offered in a wide variety of sizes and material types, suited to various applications.
