Oil Seal Size 80 100 15.5mm is a rotary shaft seal designed to retain lubricant and prevent contamination in mechanical assemblies. It features a bore of 80 mm, an outer diameter of 100 mm, and a width of 15.5 mm, making it suitable for equipment that requires this standard seal size. Key benefits Prevents oil leaks and keeps lubricant contained within the housing, helping protect bearings and related components. Shields the internal environment from dirt, dust and moisture that can cause wear and premature failure. Simple to in compatible housings, supporting regular maintenance schedules and downtime planning. Provides a compact sealing solution for tight spaces without altering the overall machine geometry. Supports reliable operation in rotating shaft applications, contributing to longer service intervals. Key attributes Functionality: oil seal (lip seal) designed for dynamic sealing of rotating shafts. Size: bore 80 mm; outer diameter 100 mm; width 15.5 mm. Compatibility: intended for use with equipment that uses an 80 mm shaft and a corresponding 100 mm seal housing; verify with OEM specifications before replacement. Material: not specified in the product title; please consult the product data sheet or listing for exact material grade and chemical resistance. Performance: designed to provide effective sealing under normal operating conditions and standard lubricant environments associated with this size. Material note Material type is not specified in the product title. For compatibility and performance, confirm the exact material grade (for example, elastomer type and hardness) from the official product listing or data sheet before ordering. Applications and use cases Automotive gearbox or transmission replacements where the drive shaft uses an 80 mm bore seal and the housing accommodates a 100 mm outside diameter seal. Industrial pumps and compressors with an 80 mm shaft requiring a 100 mm seal housing to retain oil and exclude contaminants. Conveyor drive motors or hydraulic equipment that operate with rotating shafts of 80 mm and require a matching 100 mm seal size for reliable lubrication retention. Notes for ordering Verify OEM part numbers and housing dimensions to ensure exact fitment. Check accompanying data sheet for material compatibility with the lubricants and operating temperatures in your application. If the housing or shaft tolerances exceed standard limits, consider alternatives or consult with the seal supplier for a correct fit.
