GRN VC NBR Rotary Shaft Seal 30x36x5 Single Lip

Overview

The GRN VC 30x36x5 is a high-quality single lip rotary shaft seal manufactured from NBR (Nitrile Butadiene Rubber). Measuring 30x36x5 mm, it is designed to retain lubricants while protecting rotating equipment against dust and light contamination. The VC profile does not include a garter spring, making it suitable for applications with low pressure, low friction requirements and moderate shaft speeds. It is widely used in OEM equipment, industrial maintenance and general mechanical engineering.

Industrial Applications

The GRN VC rotary shaft seal is widely used in electric motors, pumps, gearboxes, reducers, fans, conveyors, agricultural machinery, hydraulic equipment, industrial drives and automation systems. It operates together with bearings, bearing housings, rotating shafts, power transmission components and industrial sealing systems to ensure reliable lubrication retention and equipment protection.

Construction

The VC design incorporates a precision-molded single sealing lip without a garter spring. This construction minimizes friction while maintaining effective sealing against lubricants and light contaminants. The flexible NBR sealing element adapts to shaft movement, ensuring smooth operation and extended component life under standard operating conditions.

Material

The seal is manufactured from premium NBR (Nitrile Butadiene Rubber), offering excellent resistance to mineral oils, greases, hydraulic fluids, water and aliphatic hydrocarbons. NBR also provides good abrasion resistance, elasticity and durability across a wide range of industrial applications.
