Product Description
【Section 1: Product Overview 】
FB092 Rolled Split Bronze Bushing with Oil Holes
FB092 wrapped bronze bushing, also known as perforated bronze plain sleeve bearing, is manufactured by rolling CuSn8P tin bronze strip into cylindrical split bushing. The whole surface is precision punched with array oil holes to store grease and achieve continuous lubrication during operation.
Different from cast bronze bushings, rolled bronze structure has uniform density, no casting porosity, higher dimensional accuracy and cost advantage. It is widely used for heavy-load, low-speed oscillating and rotary joints, ideal choice for intermittent lubrication working conditions.
【Section 2: Core Advantages 】
✅ High Load Capacity & Wear Resistance Made of CuSn8P tin bronze alloy, high hardness, excellent anti-wear and impact resistance, can bear heavy static and dynamic load.
✅ Perforated Oil Hole Lubrication Design Uniformly distributed oil holes act as grease reservoir. Grease can be released continuously during shaft movement to reduce friction and extend service life.
✅ Rolled Split Structure, Easy Installation Split seam design allows quick assembly into housing bore, suitable for equipment maintenance and replacement. Thin wall structure saves installation space.
✅ Good Thermal Conductivity & Corrosion Resistance Bronze material quickly dissipates friction heat, avoids overheating seizure; good corrosion resistance in general working environment.
✅ Custom Machining Available Custom inner diameter, outer diameter, length, oil hole pattern and chamfer are supported. OEM & ODM service.
