Hydraulic special material for Maintenance Free Metal Dry Sliding Washer Available PTEF RED COLOR is designed according to the working principle of oil cylinder and shock absorber, which is more wear-resistant in the condition of no oil. In addition to the advantages of self-lubricating shaft sleeve, this product is especially suitable for occasions with large inclination force with frequent reciprocation.

Its performance is similar to that of overseas DP4. At present, this product has competitive price and is made in China. It is suitable for automobile, motorcycle shock absorber and various hydraulic cylinder fields.The material is lead-free and complies with the eu ROHS directive.

housing H7

shaft ø <=55: f7; >55: h8

Assembling instructions

The edges of the mounting hole and the shaft must be chamfered. It is recommended to use an arbour press. Please avoid damaging the sliding surface. The butt joint should not be in load direction.

Replacement Parts

  • Suitable for high loads
  • Multiple areas of us (universal bearing)
  • Long life
  • Wide temperature range

Red PTFE is recommended if RoHS compliance is required.

Bronze backed bushing gleitlager scheiben should be used if better corrosion resistance is required.

Standard gleitlager scheiben are manufactured to company standards and to DIN ISO.

We also provide you with suitable stamping parts according to the drawings, and label and package as required.
