FC250 Graphite Cast Steel Bearings Oilless Self Lubricating Sleeve Bearings
JDB-40 Cast Iron Graphite Inlaid Self lubricating Oilless Bushing
JDB-40 Cast iron oilless bearing is made of HT250 cast steel with graphite lubricant. This type cast steel oilless bearing is a cost saving type of cast bronze bushing. It's also called steel graphite oiles bearing, cast steel oilless bearing, graphite plugged self lubricating bushing, oilless guide bushes and solid lubricants sliding bearing.
Material
HT250 + graphite
Characteristics
- Performs great for low and middle loads and low velocity operations
- Excellent wear resistance at locations where proper oil film is hard to be formed due to reciprocating intermittent or oscillating motion
- Cost lower than bronze alloy based bearings
Availability
- Cylindrical bushing, flanged bushing, thrust washer and slide plate are standard fabrication
- Special designs can be made according to your design
Application
JDB-40 cast steel oilless bush is widely used in Guide post of mould, mold-frame of plastic injection machine etc.
