SF-1D Hydraulic Pb-free Self-lubricating Bearing

Hydraulic Pb-free Self-lubricating Bearing

Features

Besides it have the advantages of SF-1P, it is suitable for the places of big sides force of frequently reciprocate. The function is similar as DP4 in foreign country. Now it has replace the SF-1P step by step.

Material Structure

  1. PTFE with oil fibre 0.01~0.03mm
  2. Porous bronze 0.2~0.3mm
  3. Steel backing 0.7~2.3mm
  4. Tin-plating 0.005mm or copper plating 0.008mm

Available forms

Bushes, flanged bushes, WC thrust washers, strip and other non-standard parts and so on.

Application Feature

  • The thing mingles with PTFE, oleophilic fiber could form the good transform membrane to protect the rubbing each other bearing.
  • Good anti-wear, low friction value.
  • Good break in, no block appearance.
  • Could use in the active of revolve around, swing and reciprocate
  • No lead content so that it could use in the food machinery, medical machinery and other green environmental protection equipment.
  • Besides content the advantages of SF-1P, it is suit for the place of reciprocates frequently and big side force. It is suit for the dashpot and hydrocylinder in vehicle and motorbike.
