CORTECO 12011438 ACM B1KLSLRS 70x90x10 Rotary Shaft Seal

Rotary shaft oil seal for engines and left hand rotation drive systems

CORTECO 12011438 ACM B1KLSLRS 70x90x10 is a radial rotary shaft seal designed for engine systems and industrial rotating assemblies requiring stable dynamic sealing during left hand shaft rotation. The B1KLSLRS sealing profile with an additional dust protection lip is developed for applications exposed to oil, grease, contamination and elevated operating temperatures.

This seal is commonly installed in:

• combustion engines
• industrial drive systems
• gearboxes
• agricultural machinery
• automotive applications
• rear crankshaft sealing systems
• oil lubricated rotating assemblies

The seal is manufactured from ACM material.

ACM material provides:

• resistance to oils and grease
• good thermal resistance
• stable operation at elevated temperature
• resistance to material ageing
• reliable dynamic sealing durability
• stable operating performance

The B1KLSLRS designation indicates:

• radial shaft sealing construction
• additional dust protection lip
• metal outer surface
• left hand rotation design
• dynamic rotary shaft sealing geometry

The left hand rotation sealing profile supports:

• oil return toward the internal system
• stabilization of the oil film
• reduced lubricant leakage
• improved sealing efficiency during shaft rotation

The B1KLSLRS construction provides:

• effective oil leakage protection
• resistance to dust and moisture
• stable dynamic operation
• rigid housing fitment
• increased sealing durability

Seal dimensions:

• inner diameter 70 mm
• outer diameter 90 mm
• width 10 mm
