Polyurethane elastomer is a new polymer synthetic material between rubber and plastic. It has the high strength of plastic and the High elasticity of rubber.
, wide hardness range. It still has the elongation and resilience of rubber under high hardness. The hardness range of polyurethane elastomer is Shore-D and high strength. Their tear strength and load-carrying capacity are much higher at rubber hardness than general purpose rubber. Under high hardness, its impact strength and bending strength are much higher than that of plastic.
, wear-resistant. Its wear resistance is very outstanding, generally in the range of
(
)/
, which is about
times that of rubber.
, oil resistant. Polyurethane elastomer is a highly polar polymer compound that has little affinity with non-polar mineral oil and is almost not corroded by fuel oil and mechanical oil.
, good resistance to oxygen and ozone.
It has excellent vibration absorption performance and can be used for vibration reduction and buffering. Substitute rubber and springs in the mold manufacturing industry.
, has good low temperature performance.
, Radiation resistance. Polyurethane has good resistance to high-energy rays and still has satisfactory performance under high radiation doses.
, has good machining performance. (turning, milling, grinding, and drilling are all possible)
Polyurethane flexible sliding sleeves (guide sleeves) can replace metal guide sleeves to protect the wire rope to the greatest extent and greatly reduce wear and tear on the wire rope. The service life of the polyurethane sliding sleeve itself is also longer than that of metal. The product is longer. Luoyang Qiaoyang Mining Machinery Co., Ltd. supplies various types of polyurethane sliding sleeve products for wire ropes.
Our company produces and supplies various cage sliding sleeves and wire rope sliding sleeves. The material used in the sliding sleeves is a high-strength reinforced nylon polymer anti-friction and wear-resistant material. Its advantages are: long life, light weight, high strength and low price. Welcome to consult, order and purchase!

At present, there are two main guiding methods for lifting cages in coal mine shafts in my country. One is Rigid guides use rail guides and are called rail cages. The main feature of this kind of guide is that the well tower structure is simple, but the operation noise is loud and the operation is not stable enough. The general service life is about
. Another kind of guidance method is flexible guidance, which is called wire rope cage. The characteristics of this kind of guide are exactly opposite to those of the rigid guide. It has simple parts replacement, smooth operation, low noise, and good safety. However, the well tower structure is complex and generally has a service life of more than 10 years. At present, the guiding method of vertical shaft hoisting cages in my country is mainly flexible guidance.
Since the running speed of the cage is quite high, it is generally close/
. To ensure the absolute safety of the cage operation, the wear of the wire rope should be minimized during operation. Therefore, the guide sleeve is required to have low hardness and reduce wear and wear on the wire rope. Only by selecting a suitable material and formulating a reasonable production process to produce qualified products can meet production needs.
Our company’s other nylon products include: plastic linings for mining winch drums, wire rope transition rope wedges, cage guide sleeves, nylon tank ears, sky wheel liners, monkey wheels, etc.
