CuSn8 Wrapped Bronze Bushings with Grease Pockets (FB090 / WB802)

The Ultimate Solution for Heavy-Duty Agriculture & Construction Machinery

When equipment demands reliability under extreme working conditions, CuSn8 wrapped bronze bushings with grease pockets—commonly known as FB090, WB802, or 090-series bronze bearings—stand out as the industry’s preferred choice.

Made from premium CuSn8 phosphor bronze (DIN 17662 / CW453K), these thin-walled wrapped bushings feature precision-engineered diamond or circular grease reservoirs on the inner surface. These pockets store lubricant and release it gradually, enabling thousands of hours of maintenance-free or low-maintenance operation, even under heavy shock loads, vibration, and dirty environments.

Why OEMs and Farmers Rely on FB090 CuSn8 Grease-Pocket Bushings

Agricultural Machinery

Tractors • Combine Harvesters • Balers • Implements

• Three-point hitch pivot points

• Loader arm and bucket linkage pins

• Steering cylinder and kingpin joints

• Header oscillation bearings

➡️ Designed for harsh field conditions—dust, mud, and shock loads are easily handled thanks to the high-capacity grease reservoirs.

Construction & Earthmoving Equipment

Excavators • Wheel Loaders • Bulldozers

• Boom, arm, and bucket pivots

• Hydraulic cylinder rod ends and base ends

• Undercarriage tensioner mechanisms

➡️ Handles static loads up to 140 N/mm², with excellent emergency running capability when lubrication is temporarily lost.

Off-Road & Forestry Vehicles

Skidders • Forwarders • Off-highway trucks

• Suspension linkage points

• Grapple and winch joints

• Outrigger and stabilizer pivots

➡️ Offers superior corrosion resistance and better edge-load tolerance than sintered or PTFE-lined bearings.

Material Handling & Lifting Equipment

Cranes • Telehandlers • Quarry & Mining Conveyors

• Low-speed crane kingpins and slewing joints

• Telescopic boom pivot bearings

• Conveyor rollers exposed to abrasive dust

Key Advantages That Cut Costs and Reduce Downtime

• Up to 5× longer greasing intervals compared with standard bronze or steel bushings

• Eliminates the need for costly sealed or “maintenance-free” bearing alternatives

• Simple press-fit installation with split, wrapped design

• Outstanding cost-performance ratio—far cheaper than machined bronze or composite bearings while delivering equal or better durability

• Stocked in a wide range of standard sizes from Ø10 mm to Ø300 mm
