Wrapped Phosphor Bronze Bushing FB092 Split Sliding Bearing with Diamond Oil Pockets, Heavy Load Bronze Sleeve for Construction & Agricultural Machinery
[Section 1: Product Overview]
Wrapped phosphor bronze bushing, also known as rolled bronze plain bearing, is cold-formed from solid CuSn8 phosphor bronze strip. The inner surface is precision embossed with diamond-shaped oil retention pockets. These pockets store grease/oil and continuously build up lubricating film during operation, effectively lowering friction coefficient and reducing shaft wear. The split design allows easy installation and compensation for thermal expansion. Manufactured to ISO3547 / DIN1494 standard, this bushing is ideal for low-speed heavy-load sliding positions in machinery.
[Section 2: Core Advantages | Key Selling Points]
✅ Diamond Lubrication Pockets Inner diamond indentations act as lubricant reservoirs, maintain stable oil film, reduce start-up friction, extend service life.
✅ High Quality CuSn8 Phosphor Bronze Homogeneous bronze alloy, excellent wear resistance, shock resistance and corrosion resistance.
✅ Split Rolled Structure Thin wall design, easy press-fit installation; split gap absorbs thermal expansion.
✅ Wide Working Range Suitable for heavy static & dynamic load, wide temperature range from -100℃ to +200℃.
✅ Strict Tolerance Control Precision rolling & calibration, consistent dimension; Custom sizes & OEM available.
✅ Cost-effective Alternative Economical replacement for solid bronze sleeves, saves material cost without sacrificing performance.
