Featuring RK's proprietary Ultra Thin Seal U-Rings, the BL420MRU-120 uses a seal less than half the thickness of many conventional O-ring seals. This design helps reduce friction while retaining effective protection against dirt, moisture, and contaminants.\u003c\/p\u003e\u003cp\u003eEngineered for extended service life, the RK MRU chain is designed to provide up to four times the chain life of comparable non-sealed 420 chains and may require fewer chain adjustments during use.
