Key benefits Selflubricating and maintenance design combines a copper alloy with embedded graphite, releasing a lubrication layer automatically during operation to reduce friction and wear. This supports longer intervals between refueling or relubrication. strength and temperature resistance for demanding service: hard and impact resistant with strong load bearing, able to operate in a wide temperature range (20C to +250C) and withstand 300C shortterm peaks. Corrosion and environment resistance: water and steam resistant, and resistant to weak acids and alkalis, suitable for humid, dusty or mildly corrosive working conditions. Compact, compatible dimensions: inner diameter 18 mm; outer diameter 24 mm; height 15 mm, enabling versatile mounting in various assemblies. Broad applicability: designed for agricultural machinery, ships and industrial equipment, among other settings where maintenance access is limited and reliable performance is required. Key specifications Inner diameter: 18 mm Outer diameter: 24 mm Height: 15 mm Material and design: copper alloy with embedded graphite; selflubricating layer released automatically during operation Temperature range: 20 C to +250 C Shortterm peak temperature tolerance: up to 300 C Corrosion resistance: water and steam resistant; resistant to weak acids and alkalis Applications: suitable for humid, dusty or mildly corrosive environments What makes it stand out Maintenance operation due to the integrated graphite lubrication system Wide temperature tolerance supports reliability in hot and cold conditions Robust against moisture, steam and mild chemical exposure Compact size enables flexible integration across multiple machinery types Use scenarios Agricultural machinery: bearings in field equipment where regular lubrication is difficult or impractical Marine and shipboard equipment: deck machinery or winches exposed to humid or damp environments Industrial equipment: bearings in dusty or mildly corrosive environments with limited maintenance windows This description preserves the original specifications and functions while presenting clear, customerfriendly language and practical examples.
